Abstract: Advanced Encryption Standard (AES) has been developed to replace the Data Encryption Standard(DES). AES suffers from a major limitation of error propagation on its encryption process. To tackle this limitation two approaches are used: Redundancy based Technique and Byte Based Parity Technique. Redundancy based technique has some important advantages over parity based technique but at the cost of higher level of processing and lowering encryption speed. In this study we report the application of selective AES in redundancy based technique. Our technique gives better results in terms of higher throughput and higher speed of encryption over the conventional technique.
