A new approach to ward off Error Propagation Effect of AES – Redundancy Based Technique Redefined

Abstract

Advanced Encryption Standard (AES) [1, 2] is a great research challenge. It has been developed to replace the Data Encryption Standard (DES). AES suffers from a major limitation of Error propagation effect. To tackle this limitation, two methods are available. One is Redundancy Based Technique and the other one is Bite Based Parity Technique. The first one has a significant advantage of correcting any error on definite term over the second one but at the cost of higher level of overhead and hence lowering the processing speed. In this paper we have proposed a new approach based on the Redundancy Based Technique that would certainly speed up the process of reliable encryption and hence the secured communication.
