Improvising performance of Advanced Encryption Standard algorithm

The requirement of information security on a network has become highly challenging. Cryptography is a method to provide information confidentiality, authenticity and integrity. The cryptography overcomes several challenges such as execution time, memory requirement, and computation power. However, we cannot get desired outcomes by using sequential computation. In this paper, we introduce parallel computation using multicore processors by parallelizing the execution of the algorithm in multiple cores. We analyze the effectiveness of the Advanced Encryption Standard (AES) algorithm on dual core processor by using OpenMP API to reduce the execution time. This process is validated using JAVA platform. Based on the results, it is confirmed that parallel computation reduced execution time as compared with sequential computation.
