Labovian Narrative Analysis Essay Sample free essay sample

In this paper. I perform a narrative analysis on an â€Å"oral narration of personal experience† ( Labov. 2011 ) . As follows. Section 1 discusses the methodological analysis used to execute the analysis. Section 2 discusses the construction of the narrative and presents the consequences of the analysis. and Section 3 concludes with a sum-up of the narrative and analyses. Section 1: Methodology For this analysis. I used a personal experience that is termed an evoked narration. which means I asked the person to portion a narrative alternatively of trusting on of course happening colloquial informations ( Labov. 1997 ) . The narrative is told by a household relation of mine. Lisa. It is about a extrasensory experience she had as a kid in Sydney. Australia and involves the independent motion of a tabular array while Lisa and others were at an unfastened house. To analyse Lisa’s narrative. I used Labov’s original theoretical account of narrative. which breaks down a narrative into distinguishable classs: Abstract. We will write a custom essay sample on Labovian Narrative Analysis Essay Sample or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Orientation. Complicating Action. Evaluation. and Coda. In add-on. I used general Labovian narration theory to depict the temporal construction and map of Lisa’s narrative ; nevertheless. I have refrained from utilizing the term Resolution due to its ambiguity in Labov’s literature. Below. in Narrative A. the narrative has been transcribed to ease the undermentioned narrative analysis. Each independent clause is numbered. and all dependent clauses are indented below them. Narrative A: An history of Lisa’s extrasensory experience ( 1 ) Yeah. one time I had this truly interesting extrasensory experience ( 2 ) Uh. back when I was in High School in Sydney in approximately 1977. ( 3 ) my parents were house hunting( 4 ) and silent and I were look intoing out a house in Killara they were interested in. ( 5 ) Equally shortly as we stepped through the front door into the broad. sunstruck hall. ( 6 ) we were both impressed by the welcoming atmosphere in the house. ( 7 ) There were one or two pieces of furniture in the hallway including an old-timer tray tabular array which had truly old Castor wheels on it the type that don’t turn over really easy even on smooth floors like that hall. ( 8 ) The tray tabular array was standing somewhat at an angle to the wall and the forepart border was about 2 inches farther out from the wall than the rear border. ( 9 ) I noticed all this because we had been standing in the hall chew the fating to the house proprietor. Mrs. C. for a piece ( 10 ) when a adult male came to the fr ont door. ( 11 ) Mum and I were confronting off from the door and towards the tabular array. ( 12 ) Mrs. C at the door had her back turned( 13 ) but her visitant at the front door had a clear position of it ( the tabular array ) ( 14 ) No-one was standing within 5 pess of the tabular array( 15 ) and no-one was traveling about to do the floor to travel ( 16 ) but that table really swimmingly and intentionally moved in on its ain towards the wall to sit neatly parallel to it. ( 17 ) The silence was deafening! ( 18 ) The adult male at the door stopped talking for several seconds ( 19 ) so pointed at the tabular array( 20 ) and in a really rickety voice said â€Å"That table merely moved! † . ( 21 ) Mrs C merely kind of said â€Å"hmmm†( 22 ) and concluded the conversation.( 23 ) He left.( 24 ) she turned back to us.( 25 ) and continued our confab( 26 ) as though nil had happened.( 27 ) Suffice to state that was merely the first brush of several I had in that house. Section 2: Results A ; Analysis In the undermentioned subdivisions. I foremost describe the general qualities of each narrative class ; 2nd. explicate Lisa’s narrative in footings of the narrative classs ; and. 3rd. show the analysis of Lisa’s narrative in footings of Labovian narrative theory. Section 2. 05: The Most Reportable Event Before plunging headfirst into the analysis. it will turn out advantageous to specify the term most reportable event ( MRE ) . Harmonizing to Labov. any given narration is constructed around the MRE. It is the ground for the narrative in the first topographic point. Generally it refers to an uncommon or rare event that greatly affects the participants involved. The more uncommon the event appears. the less credibleness it will keep. and frailty versa. Thus it is necessary for the narrative to set up credibleness elsewhere. otherwise the narration will ensue in failure. Section 2. 1: Abstraction Abstractions. like those in academic articles. occur at the beginning of texts and supply a compendious description of the information to follow. In a sense. they indicate what the reader can anticipate the article to be approximately. In footings of personal narrations. the Abstract informs the hearer what the narrative will be approximately and that it will get down shortly thenceforth. Clause ( 1 ) of Lisa’s narrative is a great illustration of narrative abstracts: ( 1 ) Yeah. one time I had this truly interesting extrasensory experience Lisa begins her narrative by briefly saying that she experienced something beyond the normal scope of account. This statement informs the hearer that they can anticipate a narrative and decision out of the ordinary. Section 2. 2: Orientation Immediately following the Abstract. the talker sets the scene by orientating the hearer to the environing elements involved in the narrative. Labovian narrative theory refers to this as the Orientation. It has two intents: foremost. to locate the clip. topographic point. participants. and general occurrences of the narrative ; and 2nd. to set up the credibleness of the MRE. The Orientation establishes credibleness by get downing the narrative with an event that would be foolish to inquire approximately. such as ordinary events. which are events that lack involvement in themselves ( Labov. 2002 ) . Common lingual characteristics of the Orientation are past uninterrupted verbs and temporal adjuncts. In Lisa’s narrative the Orientation begins with clauses ( 2-4 ) : ( 2 ) Uh. back when I was in High School in Sydney in approximately 1977. ( 3 ) my parents were house hunting ( 4 ) and silent and I were look intoing out a house in Killara they were interested in.Here. she presents the background information needed to continue with the balance of the narrative: Sydney. a house. Lisa and others. and an unfastened house walk-through. There is no ground to inquire about how these events came approximately. because they are so commonplace. Therefore. the credibleness of the narration is non in inquiry. In add-on to clauses ( 2-4 ) . clauses ( 7 ) and ( 8 ) can be considered portion of the Orientation as good. because they contribute to the scene ; nevertheless. they have been incorporated into the Complicating Action. Unfortunately. I will non discourse the Orientation any farther due to infinite restraints. Section 2. 3: Complicating Action The Complicating Action is the narrative proper. It is what the Abstract and Orientation set up to be told. Generally it contains a set of consecutive clauses. called a narrative concatenation. which leads up to the narrative’s MRE. Each consecutive clause efforts to reply the inquiry â€Å"what happened following? † and can utilize the simple yesteryear or present tenses to travel the narrative forward. In footings of Lisa’s narrative. the Complicating Action is bookended by clauses ( 5 ) and ( 16 ) the story’s MRE. But. non all the clauses in between can be considered clauses of perplexing action. This is because they are non a portion of the narrative concatenation and service as retrospective observations. For case. clauses ( 11-15 ) focal point on the participants’ propinquity and orientation to the tabular array ; they do non come on the narrative forward. In fact. by concentrating on these ordinary events. they slow down the narrative and ris e the expectancy of the most reportable event. If we remove all the clauses that do non lend to the forward motion. the true narrative concatenation becomes evident: ( 5 ) Equally shortly as we stepped through the front door into the broad. sunstruck hall. ( 6 ) we were both impressed by the welcoming atmosphere in the house. ( 9 ) I noticed all this because we had been standing in the hall chew the fating to the house proprietor. Mrs. C. for a piece ( 10 ) when a adult male came to the front door. ( 16 ) but that table really swimmingly and intentionally moved in on its ain towards the wall to sit neatly parallel to it.These five clauses constitute the Complicating Action and. as we can see. it is comparatively short in comparing to the full narrative. Although clause ( 10 ) is necessary for the Evaluation. even the man’s debut is non critical to the narrative’s patterned advance. It is possible at that place was non much of a narrative to state. but because the credibleness of the MRE was questionable. embroidery of the narrative concatenation with ordinary. hence less questionable. events increased the credibleness of the MRE and produced a longer narrative. Section 2. 4: Evaluation The Evaluation subdivision serves a few intents. first it justifies the narrative and the talker for keeping the floor for every bit long as they have ; 2nd. it serves to set up the MRE as the ground for the narrative ; and 3rd. it provides information about what happened after the MRE and its affects on those take parting. Common lingual characteristics in appraising clauses are modals. negatives. appraising commentary. embedded address. and irrealis clauses. Clause ( 17 ) begins the Evaluation subdivision in Lisa’s narrative: ( 17 ) The silence was deafening! At this point in the narrative. it seems that the table’s eldritch motion has elicited a reaction perceptibly different from earlier events. one of deafening silence. If we assume the silence occurred during a conversation. so. in footings of Conversation Analysis. the table’s motion one-sidedly ended the conversation without negociating a shutting. therefore interrupting the norm. If no reaction were elicited. there would hold been no narrative to state. Therefore the reactionist silence serves as evidences for the narrative and establishes the MRE as the ground for the narrative. The balance of the Evaluation. clauses ( 18-26 ) . reads like a narrative concatenation in a complicating action. Except for ( 26 ) . each clause is consecutive and in simple past tense. However. unlike clauses of perplexing action. they do non come on towards an MRE. Alternatively they describe the assorted reactions to the MRE in sequence. including a deictic gesture. possible ambivalency. and going. Section 2. 5: Finale At the terminal of the narrative. the Coda maps to return the narrative to the present tense and inform the hearer that the narrative has concluded. It is frequently accompanied by a â€Å"timeless† statement. In Lisa’s narrative. the concluding clause acts as the Coda: ( 27 ) Suffice to state that was merely the first brush of several I had in that house. Lisa concludes her narrative by saying she will state nil beyond the fact that she has more narratives to state. She explains how it all terminals by stating it does non stop rather at that place. Section 3: Decision After dissecting Lisa’s narrative with a Labovian scalpel. this paper has shown that narrations are non merely simple retellings of events ; instead they are complex buildings with functional intent. As shown above. narrations have an internal construction that can be broken up into distinguishable classs: Abstract. Orientation. Complicating Action. Evaluation. and Coda. Each class provides a necessary map for the narrative. and while some hold flexible places. others do non. Ultimately. the end of a narrative is to inform the hearer of the most reportable event. while continuing its credibleness. To make otherwise would ensue in failure and a decrease of societal standing for the storyteller. As a side note. it would be interesting to look into the construction of Evaluations in other narrations and compare them with Lisa’s. It seemed to me that the reaction to the MRE had higher significance than the MRE did. but because I presently lack experience and cognition in th e field of narrative theory. I can non back up my statement. Mentions Labov. W. ( 1997 ) . Some farther stairss in narrative analysis. The diary of narrative andlife history. Retrieved from hypertext transfer protocol: //www.

Pacific Dogwood essays

Pacific Dogwood essays The pacififc dogwood is also known as the Western Flowering Dogwood or the Mountain Dogwood. The name "dogwood" is thought to be related to the early use of hardwood trees because the wood was considered skewers of "dags" and over time "dagwood" became "dogwood". Structure of the tree, leaf, stem, flower, fruit, and bark~ The Pacific Dogwood can get up to about 15 meters in height or it can appear as small as a shrub. It grows where many hardwood trees cannot because it is successful in carrying out photosynthesis under only 1/3 of full sunlight making it shade tolerant. The wood is fine grained, hard and heavy. It is also prone to splitting, so it has limited and specialized uses. The leaves are about 6-11 cm wide and 3-7 cm long. They are simple and deciduous. Their shape is elliptical to obvoate or almost round and the edges are slightly wavy with 5-6 mm long veins on each side of the midveins. The color is usually shiny green and nearly hairless above with paler woolly hairs beneath. In Autumn, their pigmentation turns red and orange. The stems are slender with a light green color that becomes dark red or blackish with age. Each one is bent to prevent overlap with other flowers. The flowers are about 6 mm wide and have 4 greenish-yellow petals. Each cluster of about 20 flowers is bordered by 4-7 bracts (4-6 cm long). They are very large, elliptical, white (or pinkish) and petal-like. These bracts protect the flower clusters and attract pollinators. They do this by not falling off until every flower in their cluster is pollinated, thus they bloom for quite some time. The bracts have a notch at the top as a result of one seen on the pruplish bud before it forms. In Autumn, purplish-brown bracts form over next springs flower buds that will bloom from April to June and sometimes again in September. The fruit is a dense cluster of elongated red to scarlet drupes about  ½ an inch long. Each fruit contai...

Function of spoken conversation Essay Example | Topics and Well Written Essays - 750 words

Function of spoken conversation - Essay Example Spoken conversation would then be the use of spoken communication to transfer ideas, information and opinions. It's the simplest and most effective way to get one's message across. After body language, it's the second form of communication that we learn, and in a way, it's the most infallible. When an infant cries for example, we know that it either a) wants something, b) is in uncomfortable, or c) none of the above and one needs to see a doctor; but we can't be sure of the exact problem. It's the reason a doctor asks a person to describe one's symptoms first; because spoken conversation is the fastest way to get information. Anyone who's played charades will understand the trouble it is to make people understand something purely using body language. Anyone who loves a pet will know how infuriating it is that one can't have a good one-on-one chat with a dog, cat, gerbil, or goldfish. When we converse with someone verbally, we have a better chance of understanding that person; as compared to communicating via email or just observing their body language. Speaking is more emphatic than any other form of interaction. When we want to emphasize our point, we strain our voices and inflect more; the interest we take in a subject can be gauged by the speed at which we speak, or the way the decibel levels in our voice change. People give away a hundred different bits of info while they talk; other than just the words that they speak (Brennen, 2004). It's a bit difficult to state the function of spoken conversation; other than the absolute obvious. We use spoken conversation to communicate cheaply (doesn't require a monthly internet charge, or permanent markers); easily and fast; and to get our idea across most effectively. The voice, like the body, doesn't have a language barrier. The way a person intonates, and the rise and fall of his voice can get his message across even if he doesn't speak your language. The dynamism of speaking is such that we never ever pronounce a word in the same way twice (Wiki Answers). Our brain is able to recognize different sound patterns and give meaning to them. A simple word "Yes" can be used to signify approval, doubt and even a "No" if spoken with different tones. In any other form of communication, yes would just mean a 'yes'. So if one is speaking, it's absolutely necessary to pay attention, otherwise you might never know what you're getting into. Spoken conversation, because of its chances of ambiguity, strains one's mind more than any other form of conversation; and that includes written conversations with one's English Literature professor. And lastly; no form of conversation is as enjoyable as spoken conversation. Wit, banter, and irony are all exchanged verbally. Arguments, heated discussions, and rants on politics and sport are as much a part of our lives as gossip exchanged on the telephone. The advent of the 'Talkies' finished off silent movies; and unemployed many silent movie actors. And now, I doubt we can even imagine sitting through a 2 hour movie that doesn't have words. We speak not because we absolutely have to, but because we need to. An average person can go quite a long time without communicating with anyone through writing, but not having someone to talk to can drive him insane. In 'Castaway', Tom Hanks stars as a FedEx delivery man stranded on an island. Among his delivery consignment he finds a football which he turns into a

Internet Marketing Essay Example | Topics and Well Written Essays - 1500 words - 1

Internet Marketing - Essay Example Online marketing may refer to all kinds of marketing done on the company website, emails written to customers and other wireless media. Customer relationship can earn a company competitive edge since good relationships build trust and, hence, regular customers. Internet marketing binds together the art of creativity and technical elements of the Internet comprising design, development, public relations, and sales. Internet marketing is mostly done through the company website and social sites like Facebook and Twitter (Maughan, 2007:58). Although the main goal of the internet marketing is to grow the company business, the company should emphasize winning customer trust by appearing genuine and promising what it can offer. This is because internet influences chances of frauds; hence, imposters can steal from customers. Zappo embraces internet marketing to sell its products, which are majorly shoes and bags. Use of the Internet to market its products is of high importance as the company encourages all employees to exploit social media networks and connect with customers following the companies’ core values. This has endowed Zappo with great support since the employees are active on Twitter, the company’s director being most popular. Zappo uses YouTube to display its products, give speeches to customers through videos, which majorly highlight company values, customer feedback and compliments. Facebook is one of its engines towards customer feedback and discussions that present an opportunity to clear doubts and instill confidence and trust. Zappo has several blogs giving information on its products, employees, and management. Blogging creates credibility and wide readership and enables customers to understand the company better as well as reduce fears. A company aspiring to succeed in online marketing should invest in a good-looking design (Rosen,

He considered the siesta as a state that is achieved at the moment that one forgets about one’s body or in psychoanalysis the state of the unconscious. Yet, his dreamlike style, combined with a variety of works with different themes dramatically changed the way the world viewed art. Salvador Dali, is one of the unconventional world renowned painters I truly admire. Dali’s artistic genius always has a shock factor when looking at his paintings. His paintings would easily capture not only your attention but also of your cognitive and aesthetic senses stimulating them to explore, rationalize and associate meanings to their symbolic details. Dali easily catches his viewers’ attention with the combination of light colors and the odd images in his paintings appearing seemingly to have no correlation at all. Dali’s The Persistence of Memory, a painting that earned him the hallmark of fame, is just an

Security system for DNS using cryptography

Security system for DNS using cryptography 1. Introduction Scope Of The Project The domain name system has become a serious equipped part of the Internet communications, though it doesn’t contain secured mechanism to guarantee data integration or verification. Extensions to DNS provides services to security awares resolves are applications through the Cryptographic digital signatures which are included as resource records and also provides storage of valid public keys in the DNS which support general public key distribution services and also DNS security. The stored keys make security aware resolvers to know authenticating key of zone and these keys can be used to maintain other protocols and extensions gives for the authenticating DNS protocol transactions also. DNS provides security using the concepts of Digital signature and Asymmetric key cryptography. In this asymmetric key is send as a substitute of private key. DNS security uses message digest algorithm to compact message and PRNG (pseudo random number generator) algorithm in order to generate this public and private key. Signature which is formed by combining message with the private key using DSA Algorithm is send along with public key To form a signature receiver makes use of the public key and DSA Algorithm. If the received message signature is matched then that message is decrypted and will be read or else it will be discarded. Problem Statement Authenticity is based on entity identification where the entity is genuine. In many network applications entity can be identified by name or addresses. In high level applications names are used for authentication as the address lists are difficult to create, to understand and also for maintaining Assume if an entity wants to take off other entity identification, then it is enough to change mapping between low level address and its high level name which means that attacker can forge someone’s name by changing the address associated from his name to those name he wants to takeoff. If this happens an authenticator cannot differentiate between the correct and false entity. 2. Overview Of The DNS In order to connect a system which supports IP then the initiating host should know the IP address before only which is a 32-bit number and it represents the system location in a network and this address is divided into four octets which are separated by a dot character(â€Å".†) and each octet is represented by a decimal number. Though it is easier to remember this four decimal numbers than thirty two 1’s and 0’s,a limit as to how many IP addresses can be remembered by a person without any directory support. Directory basically assigns hosts names to IP addresses . The Stanford Research Institute’s Network Information Center (SRI-NIC) became the responsible authority for maintaining unique host names for the Internet. The SRI-NIC maintained a single file, called hosts.txt, and sites would continuously update SRI-NIC with their host name to IP address mappings to add to, delete from, or change in the file. As the Internet grew rapidly, managing the files become difficult and also the hostnames required to be unique allover the worldwide internet. As the internet size increases the guarantee the uniqueness of host name became impossible. The need for hierarchical naming structure and distributed management of host names lead for the creation of a new networking protocol that was flexible enough for use on a global scale [ALIU]. Internet distributed database is created and this maps the computer system’s names with their respective numerical IP network address. This Internet lookup facility is the DNS. Delegation of authority is important to the distributed database. No single organization is responsible for host name to IP address mappings for longer, but somewhat those sites that are responsible for maintaining host names for their organization(s) can gain that control again. Fundamentals Of DNS The DNS not only supports host name to network address resolution, known as forward resolution, but also network address to host name resolution, known as inverse resolution. This ability of mapping human memorable system names into computer network numerical addresses, its dispersed nature, and its strength, the DNS has become a vital component of the Internet. Without DNS, the only way to reach other computers on the Internet is to use the numerical network address. Connecting a distant computer system using IP addresses is not much user-friendly illustration of a system’s location on the Internet and thus the DNS is heavily relied upon to get back an IP address by referencing just a computer systems Fully Qualified Domain Name (FQDN). A FQDN is mainly a DNS host name which represents where to decide this host name within the DNS hierarchy. Related Works The Domain Name Space The DNS is a hierarchical tree structure. Its root node is known as the root domain. A label in a DNS name directly corresponds with a node in the DNS tree structure. A label is an alphanumeric string that exclusively identifies that node from its brothers. Dot notation (â€Å".†) is used to connect labels together and labels are written from left to right. A DNS name that contains several labels represents its path along the tree to the root. Only one zero length labels are accepted and reserved for the root of the tree. This is referred to as the root zone. As the length of the root label is zero, all FQDNs end in a dot [RFC 1034]. As a tree is traversed in an rising manner (i.e., from the leaf nodes to the root), the nodes become increasingly less specific (i.e., the leftmost label is most specific and the right most label is least specific). Typically in an FQDN, the host name is the left most label , while the next label to the right is the local domain to which the host belongs. The local domain can be a sub domain of another domain. The name of the parent domain is then the next label to the right of the sub domain (i.e., local domain) name label, and so on, till the root of the tree is reached   When the DNS is used to record an IP address back into a host name (i.e., inverse resolution), makes use of the same scheme of labels from left to right (i.e., most specific to least specific) when writing the IP address. This is in contrast to the typical demonstration of an IP address whose dotted decimal notation from left to right is least specific to most specific. For this, IP addresses in the DNS are usually represented in reverse order. IP addresses comes under a special DNS top level domain (TLD), known as the in-addr.arpa domain. By doing this, using IP addresses to find DNS host names are handled just like DNS host name lookups to find IP addresses. DNS Components The DNS has three major components, the database, the server, and the client [RFC 1034]. The database is a distributed database and comprises of the Domain Name Space, which is basically the DNS tree, and the Resource Records (RRs) that define the domain names within the Domain Name Space. The server is generally referred to as a name server that is usually responsible for organizing some portion of the Domain Name Space and also for supporting clients in finding information within the DNS tree. Name servers are authoritative for the domains in which they are responsible. They serve as a delegation point to identify other name servers that have authority over sub domains within a given domain. The zone information is the RR data found on the name server that makes up a domain Thus, name servers have zones of authority. A single zone can either be a forward zone (i.e., zone information that pertains to a given domain) or an inverse zone (i.e., zone information that maps IP addresses into DNS host names). DNS allows more than one name server per zone, but only one name server can be the primary server for the zone. Changes to the data for a zone takes place in Primary servers. Copies of the primary server’s database are maintained in all other name servers for a zone. These servers are called as secondary servers. . A DNS RR has 6 fields: NAME, TYPE, CLASS, TTL, RD Length, and RDATA. The NAME field holds the DNS name, to which the RR belongs. The TYPE field is the TYPE of RR. This field is necessary as it is common for a DNS name to have more than one type of RR. The more common types of RR are found in The CLASS in this case is IN and it stands for Internet. Other classes also exist but are omitted for brevity. The TTL is the time, in seconds, that a name server can cache a RR. A zero time to live means that a server is not to cache the RR. RD Length is the length of the RDATA field in octets. The RDATA field is the resource data field which is defined for each TYPE of RR uniquely, but in common it can be considered as the value into which the entity specified in the NAME field maps. The NAME field can be thought of as the subject of a query, although this is not always the case, in RDATA field the answer is the contained data (even though the entire RR is returned in a DNS response) [RFC 1035]. RRs are grouped into resources records sets (RRSets). RRSets contain 0 or more RRs [RFC 2136] that have the same DNS name, class, and type, but (i.e., RDATA) different data. If the name, type, class and data are the same, for two or more records then there exists a duplicate record for the same DNS name. Name servers should suppress duplicate records [RFC 2181]. The Figure 3 shows an example of an RRSet. The client component of the DNS typically contains software routines, known as functions that are responsible for requesting information from the Domain Name Space on behalf of an application. These functions are bundled collectively into a software library, commonly referred as the resolver library. For this reason, clients are often called resolvers and resolver documentation functions are dependable for sending a query to a name server requesting information concerning a DNS name and returning the answer to the query back to the requestor. DNS Transactions DNS transactions occur continuously across the Internet. DNS zone transfers and DNS queries/responses are the two most common transactions. A DNS zone transfer occurs when the secondary server updates its copy of a zone for which it is authoritative. The secondary server makes use of information it has on the zone, namely the serial number, and checks to see if the primary server has a more recent version. If it does, the secondary server retrieves a new copy of the zone. A DNS query is answered by a DNS response. Resolvers use a finite list of name servers, usually not more than three, to find out where to send queries. If the first name server in the list is available to answer the query, than the others in the list are never consulted. If it is unavailable, each name server in the list is consulted until a name server that can return an answer to the query found. The name server that receives a query from a client can act on behalf of the client to resolve the query. Then the name server can inquiry other name servers one at a time, with each server consulted being most likely closer to the answer. The name server that has the answer sends a response back to the original name server, which then can store the response and send the answer back to the client. Once an answer is cached, a DNS server can use the cached information when responding to consequent queries for the same DNS information. Caching makes the DNS more capable, especially when under heavy load. This efficiency gain has its tradeoffs; the most important is in security. Proposed System Taking the above existing system into concern the best solution is using Pseudo Random Number Generator for generating Key Pair in a quick and more secured manner. We use MD5 (or) SHA-1 for producing Message Digest and Compressing the message. Signature is created using Private Key and Message Digest that is transmitted along with the Public Key. The transfer of the packets from each System to System is shown using Graphical User Interface (GUI). Each time the System get the message, it verifies the IPAddress of the sender and if match is not found then discards it. For verification, the Destination System generates Signature using Public Key and DSA Algorithm and verifies it with received one. If it matches it Decrypts else it discards. The Following functions avoid the pitfalls of the existing system. Fast and efficient work Ease of access to system Manual effort is reduced 3. DNSSEC In 1994, the IETF formed a working group to provide the security issues in the DNS protocol are surrounding the DNS. And these extensions are referred commonly to as DNSSEC extensions. These security enhancements to the protocol are designed to be interoperable with non-security aware implementations of DNS. The IETF achieved this by using the RR construct in the DNS that was knowingly designed to be extensible. The WG defined a new set of RRs to hold the security information that provides strong security to DNS zones wishing to implement DNSSEC. These new RR types are used in combination with existing types of Resource Records. This allows answers to queries for DNS security information belonging to a zone that is protected by DNSSEC to be supported through non-security aware DNS servers. In order to gain widespread approval, the IETF DNSSEC WG acknowledged that DNSSEC must provide backwards compatibly and must have the capability to co-exist with non-secure DNS implementations. This allows for sites to move around to DNSSEC when ready and allows less difficulty when upgrading. This also means that client side software that are not DNSSEC aware can still correctly process RRSets received from a DNSSEC server [CHAR]. In March of 1997, the Internet Architecture Board (IAB) met in order to discuss the development of Internet security architecture. Existing security mechanisms and those that are under development, but have not yet become values, that can play a part in the security architecture were identified in this meeting.. They even found the areas where adequate security cannot be achieved using existing security tools. Core security necessities for the Internet security structural design was recognized in this meeting. DNSSEC is one of the security protocols recognized as core and the protection that it provides false cache information against injection information is important to the core security requirements of the Internet [RFC 2316]. DNSSEC Objectives: A basic principle of the DNS is that it is a public service. It requires accurate and steady responses to queries, but the data considered as public data. As such, it is existed in integrity and for validation, but not for access control and privacy. Thus, the objectives of DNSSEC are to provide authentication and integrity to the DNS. Authentication and integrity of information held within DNS zones is generated through the use of public key technology and provided through the use of cryptographic signatures. Security aware servers, resolvers, and applications can then take advantage of this technology to guarantee that the information obtained from a security aware DNS server is true and has not been changed. Although the DNSSEC WG chose not to provide confidentiality to DNS connections, they did not remove the ability to provide support for confidentiality. Other applications outside of the DNS may choose to use the public keys contained within the DNS to provide confidentiality. Thus the DNS, in real meaning, can become a worldwide public key distribution mechanism. Issues such as cryptographic export are not, and may never be, solved worldwide; however, the DNS provides mechanisms to have multiple keys, each from a different cryptographic algorithm for a given DNS name, as a means to help improve this problem. Performance Considerations: Performance issues are a concern for the security extensions to the DNS protocol and several aspects in the design of DNSSEC are besieged to avoid the overhead linked with processing the extensions. For example, formulating another query that asks for the signature belonging to the RRSet just retrieved is not necessarily the most efficient way to regain a signature for the RRSet. This additional query is avoided whenever possible by allowing information retrieved from secured zones to be accompanied by the signature(s) and key(s) that authenticate the information. DNSSEC Scope: The scope of the security extensions to the DNS can be summarized into three services: key distribution, data origin authentication, and transaction and request authentication. Key Distribution: The key distribution service allows for the recovery of the public key of a DNS name to confirm the authenticity of the DNS zone data, and it also provides a means through which any key linked with a DNS name can be used for purposes other than DNS. The public key distribution service supports several different types of keys and key algorithms. Data Origin Authentication: Data origin authentication is the heart of the design of DNSSEC. It mitigates such threats as cache poisoning and zone data compromise on a Domain Name System server. The Resource Record Sets within a zone are cryptographically signed and thereby giving a high level of assurance to resolvers and servers that the data just received can be trusted. Digital signature technology which contains the encrypted hash of the RRSet that is a data in the RRSet, it is the cryptographic checksum is used by DNSSEC to sign DNS RRSet. The hash is signed (i.e., digitally encrypted) using a private key belonging to the designer of the information, known as the signer or the signing authority. The digital signature is checked by the receiver of the RRSet against the data received in the RRSet. This is done by first decrypting the digital signature using the public key of the signer to get the original hash of the data. Then using the same cryptographic checksum algorithm, the recipient computes its own hash on the RRset data and the results of the hash found in the digital signature are compared with the hash just computed. If the values of the two hash matches, then the data has consistency and the origin of the data is true [CHAR]. DNS Transaction And Request Authentication: DNS requests and DNS message headers can be verified using DNS transaction and request confirmation. This guarantees that the answer is in response to the original query and that the response came from the server for which the query was intended. Thus the assurance for both can be done in one step. Part of the information, signature produced from the concatenation of the query and response is returned in a response to a query from a security aware server. This allows a security aware resolver to perform any necessary verification concerning the transaction can be performed by the security aware resolver Another use of transaction and request verification is for DNS Dynamic Updates. Without DNSSEC, DNS Dynamic Update does not provide a mechanism that prohibits any system with access to a DNS reliable server from updating zone information. In order to provide security for such modifications, Secure DNS Dynamic Update incorporates DNSSEC to give strong verification for systems allowed to dynamically manipulate DNS zone information on the primary server [RFC 2137]. DNSSEC Resource Records: The IETF created several new DNS RRs to maintain the security capabilities provided by DNSSEC extensions. The RRs related to the DNS are the KEY RR, SIG RR, and the NXT RR. DNSSEC utilizes the KEY RR for storing cryptographic public keys, one public key per KEY RR. It is the KEY RR that is used for proof of a DNS RRSet’s signature. SIG RR contains the signature for a RRSet that is used to prove the authenticity and integrity of the information in the RRSet. The NXT RR is the nonexistent RR and is used to cryptographically assert the nonexistence of a RRSet. CERT RR is another RR that does not bring any additional security functions to the DNS, but is provided so that public key certificates can be kept within the DNS for use in applications outside of the DNS [RFC 2538]. In much the same way an application wishing to communicate with a distant IP host generates a query to resolve the host name, a security application wishing to make encryption with another entity, generates a CERT query to getback the entity’s public key certificate. For further explanation on KEY, SIG, and NXT RRs and their RDATA fields and flags not contained herein, please reference RFC 2535 and related documents. KEY RR KEYRR contains the key for a DNS name. Any type of query for a DNS name, found in a secured zone, results in a response that contains the answer to the query. The KEY RR linked with the DNS name can accompany this response. The KEYRR is used to validate the data by the resolver that generated the query without sending another query for the Key RR and there by reducing the queries required for a DNS name in a secured zone. KEY RR is used by DNSSEC for storing cryptographic public keys; though, it is not a public key certificate. Instead, the CERT RR stores public key certificates. The key found in the RDATA section of the KEY RR belongs to the DNS name that is listed first in the KEY RR .The owner name can represent a zone, a host, a user, et al. The Key RR contains information regarding the security characteristics of the key and it’s allowed usage for the given owner name. security information such as the public key, algorithm type, protocol type, and flags that specify such things whether the DNS name has a public key or not are provided by Key RR. The actual format of the public key found in the RDATA section of the KEY RR is determined by the public key algorithm. Many key algorithms are supported and are defined in RFC 2535 as RSA/MD5, Diffie-Hellman, and Digital Signature Algorithm (DSA), and the elliptic curve algorithm. Only DSA support is compulsory. The protocol octet is another field that indicates for which protocol the public key is valid. TLS, email, DNSSEC, and IPsec are some of the previously assigned protocols. As both the public key algorithm field and the protocol octet is an 8-bit field, theoretically up to 255 different algorithms and 255 different protocols can be used in combination with the pub lic key. Out of the sixteen bits used for setting various flags two bits are known as the type bits. All four combinations of the type bits show the usage of KEY RR. They are confidentiality, authentication, confidentiality and authentication, or none. The last one indicates a key does not exist for the DNS name. In this way, one can cryptographically states that the given owner name does not have a key though it is in a secure zone. Other two bits are used to identify three kinds of entities for which this key belongs, such as user, zone, or something that is not a zone. Indicating a host with these flags is actually done by using the flags to indicate that the Information of the DNS zone which is on the primary server. Thus a host is implied rather than specified by the flags. SIG RR: SIG RR is another resource record type. It contains a signature and also provides verification for an RRSet and the signature’s validity time. In a secure zone, an RRSet has one or more SIG RR associated with it and this scenario of having more than one SIG RR for a given RRSet arises if more than one cryptographic algorithm is used for signing the RRSet. Some sites may choose to do this for issues such as cryptographic export restrictions. RDATA section of a SIG RR has a number of fields. In the signature field the signature is belonged to a specific RR. A type covered field is used to indicate the RRtype of the RRSet (NS, MX, PTR, etc.). The signer’s field contains the signer’s name which a resolver or server should know for verifying the signature. The SIG RR has an algorithm field and it is identical to that KEY RR. Since signatures have termination times, as do individual RRs, the SIG RR has numerous time fields. The SIG RRs used for request authentication and transactions and for these are specially the target of a query, security attentive servers try to include in the response the SIG RRs needed to authenticate the Resource Record Set. Hence, a server will receive an answer to an RRSet and it is belonging to a secure zone that does not have the SIG RR. This situation can normally happen when a size limitation is exceeded due to the SIG RR or when a response comes from a non-security aware server. Under these circumstances, the security aware server is essential for another query especially requesting any missing SIG RRs required concluding the confirmation process. NXT RR: DNS provide the ability to cache negative responses. In the RRSet negative response does not exist for a query. DNSSEC provides signatures for these nonexistent RRSets, so these nonexistence RRSets in a zone can be authenticated. By using the NXT RR that is used to identify a variety of DNS names that are not available or for an existing DNS name a wide range of RR types that are unavailable. For nonexistent DNS names two possibilities are exist. First one is that the DNS names don’t contain any RRs; it simply may not exist. The other one is that the RR type in the query does not exist, but the DNS name will be exists. And in this all the records are arranged in alphabetical order to handles the proof of non existence of a DNS name. This method is used for canonical order and is defined in RFC 2535. Then when a query is received for a nonexistent name, after the name in the query is sent back a NXT RR containing the DNS name of the next DNS RRSet occurring canonically or alphabetically†. With the DNS name a NXT record is sent back and the RR types that the name does in fact has to handle a proof of nonexistence of a RR type for an accessible DNS name . When SIGRRs are generated for a zone the entire NXTRRs for a zone should be generated. Within the DNS Security conscious DNS servers are the source of all security-related information. Three main functions of any primary DNS server are managing the caching of DNS information and managing authoritative zone information and respond to client queries. A primary DNS server has more responsibilities to each of these functions because of security conscious. In a zone’s master database file security aware server includes the addition of SIG, KEY, and NXT RRs for an Authoritative zone information management system. The RRSets is generated for the SIG RRs and these are belonging to a zone. For generating the SIG belongs to the zone we are using a private key and itself as these private keys of servers are mostly found in on-line, it is feasible that these keys could be compromised. In contrast, the zone’s private key is reserved off-line for the majority purposes, so its compromise is less likely and the power of the data is further certain and is retrieved occasi onally to re-sign all the records found within the zone. Once the new SIG RRs are generated they are included with the rest of the information in the zone’s master file and whenever SIGRRs are generated these NXT RRs should also be generated on the server and is located into a zone’s master file. At the server side on-line signing also occurred. For DNS queries the transactions and request authentication, the server preparing the reply and that reply must use its private key and that private key is for signing. Moderately the zone key since it is reserved off-line. In the other case in which a zone key is not used for signing is for transaction. For dynamic updates the request authentication is used. The private key of the host creating the request and that request must be used. In very rare cases as DNS queries and active update requests can occur, the signer’s private keys must be maintained on-line. The protection of these on-line private keys is of extreme significance; though these are protected ahead of the scope of the paper. RFC 2541 discusses the operational considerations of SIG RR and KEY. A security aware server must properly control the caching of all security related RRs for doing a caching. The maintaining of a four cache states starts with the extra duty in caching of a security aware server starts. One state, which has a succeeding state in a non-security aware server, is Bad. When a bad reply is received the information contained in that is some way corrupt, and a non-security aware server throws away the reply message without caching it (and typically logs the event) in a non-security aware server. In much the same way, a security aware server can throw away a bad response, but in this case, a bad response means that the SIG RR verifications are failed on the data. Even still the RRSet in the response may look valid, and with the related signature fault of the data checks is a severe condition. In the RRSet Authenticated, Pending and Insecure are the other three states. There is no available data to use to ensure the accurateness of the RRSet in Insecure state. It does not mean the data is bad, just that it cannot be authenticated. This usually occurs from non-secured zones for RRSets. The RRSet cached has been fully definite through the use of the SIG RRs and KEY RRs is called Authentication. The cached data is still in the course of being checked is called pending. When to expire a cached RRSet another server task is caching. Once an RRSet is cached, a count down to zero from the original TTL is started and it is maintained for the cached record. The RRSet is separated from the cache once zero is reached. The cache has changed a slight for security aware servers. When a cached RRSet is expired the TTL could not be the only time to find out the cache. Two new times are now used in addition to the TTL and these finally decide when to expire the RRSet from the cache. The new times are used to find when the signature’s validity time period for the authenticated RRSet expires, rather than just when the RRSet should be expired. These original times are kept in the SIG RR and are known as the signature begins time and the signature end time. For security aware clients and server this information is distant more essential on which to base expiration since it is cryptographically declared. Since the signature end time seems have a link to the TTL , the TTL field cannot be removed due to the backward compatibility issues. For expiring valid RRSets TTL aging is still integrated. If the TTL expires earlier to the signature end time, and the RRSet is decomposed when the TTL strikes zero, the TTL is decremented as normal. If the signature expiration time occurs previous to when the TTL expire, the TTL is familiar to the signature end time and then the normal countdown of the TTL is continued. Both security aware and security unaware resolvers involve answering queries, when a client is responses to a query. In a secured zone the non security aware resolver produces a query and sends it to a security aware server for gaining the information. With either valid or timid data the security aware servers can respond. The checking disabled (CD) flag is set when a security aware server sends the pending data. The security aware server knows not to send Pending data since a resolver not participating in DNSSEC in no way sets the CD flag in a DNS query. The security unaware resolver processes the reply message as common, since sending insecure data is same as DNS without DNSSEC. The security unaware resolver ignores the additional security information till it receives the valid data and it gives the response as normal.

Aruba :: Free Descriptive Essay About A Place

Aruba Aruba’s political center was located on the island of Curacao while under the colonial control of the Netherlands from 1634 until 1986. Decisions on political issues in Aruba were made by the Dutch Governor who was located on Curacao. With the economic boom of the oil refineries in the 1900’s, the people of Aruba started to feel the need to have a say in issues facing them. Many political issues were put on hold because of World War II and the German occupation of the Netherlands from 1940 to 1944. With the world at peace, the issue of the post war handling of their colonies had to be faced by the Dutch. The Netherlands Antilles, which includes------------------- was granted universal adult suffrage in 1950 and internal self-government in 1950. After four years of considerable discussion, the Dutch government and its American colonies adopted an unusual constitutional experiment, the Statute of the Realm, which became effective in December 1954. Under the Statute, the Dutch monarch reined over a composite realm made up of the three kingdoms of the Netherlands, Suriname, and the Netherlands Antilles. The statue grants the Dutch islands considerable autonomy. The realm has jurisdiction over defense, foreign affairs, the sharing of citizenship, and certain other specific matters. All other governmental powers are reserved to the former colonies. Even in foreign affairs, the Netherlands Antilles can join international bodies, and the Realm may not make or break treaties affecting its Caribbean members without their consent . The Kingdom of the Netherlands Antilles formed the Antilles Federation. The center of political power for Aruba during the colonial period was located in Curacao. With the coming changes resulting from World War II, the real issue brought forward before the war was not resolved. A government located on Curacao still ruled Aruba. Leaders of Aruba remained convinced that Curacao treated them unfairly and unjustly obtained too much of their income. The Netherlands maintained that any island leaving the federation must become an independent nation. As Aruba’s economy was boosted by the establishment of the Standard Oil Company of New Jersey (Exxon)’s largest refinery in the world in 19----------------, the cry for independence (or â€Å"Status Aparte†) became more and more vivid. During this period the political parties A.V.P (Arubaanse Volks Partij) and U.N.A. (Union Nacionalista Arybano) governed the island.
