Abstract :
AES advanced encryption standard algorithm was designed to resist classical methods of cryptanalysis (e.g. linear or differential attacks), which were based on probabilistic characteristics. But, it has not mature immunity against algebraic attacks which becomes more powerful after the emergence of XSL algorithm. In this research we tried some methods to increase the immunity of AES algorithm against these algebraic attacks. Then we studied the effect of the proposed enhancements on the immunity of AES new algorithm.
