Performance Improvement of Advanced Encryption Algorithm using Parallel Computation

The requirement of information security on network has become more and more important. Cryptography is a method to provide information confidentiality, authenticity and integrity. There are so many challenges to implement cryptography algorithm such as execution time, memory requirement, and computation power. Parallel computation is a promising technique to improve the performance of cryptography algorithm. Mainly divide-and-conquer strategy is used in parallel computation to solve the algorithms in parallel by partitioning and allocating, number of given subtask to available processing units. Parallel computation can be performed using multicore processors by parallelizing the execution of algorithm in multiple cores. In this paper we explore the implementation of AES (Advanced Encryption Algorithm) cryptography algorithm on dual core processor by using OpenMP API to reduce the execution time
