Parallel Computing Of Cryptography A Literature Review

PARALLEL COMPUTING IN CRYPTOGRAPHY A Literature Review Presented to Sharmin Khan Department of Computer Science San Jose State University In Partial Fulfillment of the Requirements for the Class CS 200W By Rachel Gonsalves May 2016 Abstract In today’s world a lot of data is being exchanged via the internet. Sensitive data such as official documents, bank details, credit card information, as well as personal information is being sent online. To maintain the confidentiality, integrity and availability of this data, it needs to be encrypted. Cryptology deals with cryptography and cryptanalysis, i.e., encryption and decryption of information. To keep the data safe from intruders, various cryptographic algorithms are implemented. Parallel processing enhances the speed of these systems and makes it more efficient. Parallel computation can be performed using multicore processors by parallelizing the execution of algorithms in multiple cores. The main area of focus will be the parallelization of Advanced Encryption Standard (AES) algorithm, which is widely in use today. The paper reviews the implementation of AES algorithm on multiple cores and the speedups observed in the process. TABLE OF CONTENTS 1. Introduction 4 2. Cryptography 5 3.

Information security plays major role in computer and network security with the use of different cryptography algorithms that includes the encryption and decryption of data with the uses of the algorithm and the key. By means of text or numerical key for the encryption can be dangerous because with the several hack attacks that a key can be broken.

Will, who is the main character, works as a janitor at an elite college, but he is actually a genius. Professors discover his ability after Will proves a mathematical theorem anonymously on a chalkboard at the college. Despite his intelligence, he has a criminal record and violent tendencies.

The bar scene is early in the movie. Will and his group of friends Chuckie, Morgan, and Billie are at a Harvard college bar. Almost all the patrons are people who come from an upper class segment of society. An egotistical male Harvard st udent named Clark confronts Chuckie while he is hitting on two of the college girls. Clark automatically looks down on Chuckie and attempts to belittle his intelligence. Will watches from the shadows of the bar, but quickly comes forward to defend his friend. He confronts Clark using his witty, intelligent banter to discredit Clark’s attempt at proving his superiority. Will counters every verbal jab thrown his way, before making an unexpected physical threat to end the confrontation.
