摘要
对AESS盒的阶次运算进行了研究,发现AESS盒的连续状态转移是一个马尔可夫链,其256个状态可以划分为5个常返态闭集,状态周期分别为59,87,81,27,2。
The order of AES S-box is studied and it is found that the S-box continuous state transformation is a Markov chain. The whole 256 states fall into 5 closed gathers that always return their original states and their respective periods are 59, 87, 81, 27, and 2.
