A NOVEL ARCHITECTURE FOR INVERSE MIX COLUMNS OPERATION IN AES USING VEDIC MATHEMATICS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 1
Abstract
In the fast growing world, with the advent of new technologies, people communicate via internet on a day to day basis. Secure transactions such as banking, bill payments, mail delivery, etc. are being carried out easily via smart phones, tablets and computers. Thus, providing information security through encryption and decryption plays a very important roll. Many algorithms have been implemented so far to provide data encryption, of which Advanced Encryption Standard (AES) is one such efficient algorithm. In this paper, a novel method has been proposed for the mix columns and inverse mix columns operation in AES cryptography, which is a major operation that provides diffusion of data i.e. the plain text. A software implementation is done using VERILOG Hardware Description Language, using the three methods: Look-up table method, Splitting method over Galois field and the proposed, Vedic mathematics technique. It can be found that the Vedic mathematics approach provides an area efficient and high speed algorithm when compared to the other two methods
