Design of Advanced Encryption Standard (AES) based Rijindael Algorithm

Abstract

Advanced standard encryption standard is mainly used for various security applications. Application specific integrated circuit (ASIC) with cryptographic algorithm is generate the efficient security levels for various applications. Rijindael algorithm works with encryptions and decryptions. Encryption is transform the transformations from plain text into cipher text and decryption are performs the reverse function of encryption. Mix column and inverse mix column is one of the complicate process to perform the encryptions and decryptions. In general, there are required number of the logical elements is comparatively high for the mix column and inverse mix column process. To provide the efficient logical elements for the mix column, the enhanced inverse mix column is proposed in this paper. These works improve the logical elements utilizations as well as the power optimizations. The enhanced mix column produces the efficient Area, Delay and Power(ADP) products for the both encryption and decryptions.
