Encryption of data in transit and data at rest Research Paper

Encryption of data in transit and data at rest - Research Paper Example Encryption in the field of computer security is a process that allows users to encode their data using a certain key or a certain algorithm. Through the use of encryption a user is able to enhance the security of his or her data. Even though encryption of data does not necessarily restrict the access of data it however does ensure that a hacker is not able to interpret encrypted data and hence use it for personal benefit. Encrypted text is usually referred to as cipher text whereas unencrypted text is referred to as plaintext. Encryption is usually made use of for two basic data types, data in transit and data at rest. Data in transit usually refers to data that is on the move, whereas data at rest refers to stored static data that is used on a few numbers of machines. Encrypting data in transit is usually carried out through the use of private and public keys. Private keys are usually made use of to encrypt the main data that is important to a particular organization or to a particular user. The sender usually makes of an encryption key that only the receiver is aware of. The receiver then makes use of the same key to decrypt the information that is provided by the sender (Salomaa, 1996). Public key on the other hand, is used to facilitate the exchange of the private key. Public key is made use of to encrypt the private key. The sender of the data asks the receiver to provide him or her for an encryption key. The key is then used by the sender to encrypt the message. Once the message is encrypted, its decryption can only be carried out by the receiver (Salomaa, 1996). When it comes to securing data at rest, there are two basic process that can be used, encryption and authentication. Encryption to data at rest can be applied at a small scale, such as to a sensitive file, or it can be applied at a large scale, for example to the complete contents of a device (Scarfone et al., 2007). The type of encryption technique that is

Jonathan Safra Foer Extremely Loud and Incredibly Close (2005) Literature review

Jonathan Safra Foer Extremely Loud and Incredibly Close (2005) - Literature review Example For instance, in William Golding’s Lord of the Flies the innocent respond to the apocalypse by hopelessly degenerating into abject crudeness and barbarity, thereby questioning the supposed nobility of human existence and the lofty achievements of human civilization (Otten 1982). In contrast, To Kill a Mockingbird by Harper Lee shows the innocent witnessing the rampant social injustices with their inherent simplicity and artlessness, without attempting any analytical or immaturely logical approach towards trying to figure out things (Sterne 1994). In Khaled Hosseini’s The Kite Runner, the innocent succumb to the defilement of cherished intimacy and friendship before an abject sense of helplessness and painful unconcern (Shivani 2007). In that context, Jonathan Safran Foer, in Extremely Loud and Incredibly Close affects a unique treatment to the theme under consideration, in the sense that it celebrates the survival of innocence, signified by its very ability to feel pain , trauma and loss and its adamant stubbornness to seek out a meaning in the surrounding gloom and apathy. In Extremely Loud and Incredibly Close, nine year old Oskar is an innocent from the 21st century, who, though, inflicted by the sorrow and loss affected by a very contemporary apocalypse, refuses to give up. On the contrary, he chooses to squarely grapple with the bizarre aftermath wrecked by the apocalypse, painstakingly and deliberately looking out for solutions, trying to eke out explanations, desperately desiring to cull out some sense out of the world obsessed with nihilism. Story of Oskar depicts how the innocent collide with reality in the modern times. According to Claude Peck, Extremely Loud and Incredibly Close is not as much a novel about 9/11, but rather a literary after-effect, which tends to illustrate the varied imaginative and psychological dimensions of the apocalypse (2005). To explore this modern day apocalypse, Foer had to improvise an offbeat format marked b y vivid pictures, photos and illustrations portraying themes and scenes from the novel, empty pages and pages having only one sentence, coloured graphics, doodles, typographical oddities and a strange ending involving multiple pages showing a man falling from a skyscraper (Peck 2005). The novel vividly delineates how innocent Oskar tries to come to terms with his personal loss and trauma, his resultant bouts of anxiety, insomnia, self-mutilation and depression (Peck 2005). In many ways, Oskar is an exceptional nine years old, as he is a vegan, regularly corresponds with Stephen Hawking, can converse in passable French and is an avid and ingenuous inventor. However, one thing that Oskar has in common with all the New York children, and actually with many of the New Yorkers, is his deep seated sense of remorse and despair over the 9/11 World Trade Centre attack (Peck 2005). Surprisingly, Oskar responds to this tragedy by zealously trying to translate his anguish into pragmatic action, into some meaningful search that culminates into something life affirming, a possible resuscitation of the bruised yet indefatigable spirit of modern humanity (Peck 2005). Sadly, Oskar’s approach towards facing reality is not so liked by some prophets of the yore. Perhaps, as usual they consider innocence and naivety to be synonymous. In a review written for the New Yorker, John Updike commented on the futility of filling a 300 plus page book with â€Å"
