A specific class of differential cryptanalytic approach , known as related key impossible differential attack , has been successfully applied to several symmetric cryptographic primitives in particular encryption schemes such as advanced encryption standard AES. in this paper we propose a new related –key impossible differential attack on 7–round AES–128 which is the first attempt using this technique. we haveattacked 7–round AES–128with the time complexity of 2 105 , the fastest attack of all the previous ones from time and precomputation compexities points of view.<\div>

In this paper we introduce a new cryptanalytic algorithm for evaluating hash functions based on coding theoretic approach which was first used by chabaud and joux to analyze SHA–0.their method is based on finding codewords with low hamming weights where the linearized compress function is modeled by a linear code . canteaut and chabaud a method for finding codewords with low hamming weight . we improve this method by modifying their algorithm. besides using a viterbi–like algorithm we introduce a method for solving the problem with much lower computational complexity and relatively more efficiency.<\div>
