AES加密算法及S-box改进策略

AES Encryption Arithmetic and S-box Improved Strategy

介绍了高级加密标准AES加密算法的理论基础与实现,详细分析了AES加密算法中S-box的迭代输出周期性,提出了S-box的改进策略,提高了AES算法抗击差分密码分析及线性密码分析的能力。

This paper introduces the principle and the realization for the advanced encryption standard AES encryption arithmetic, and analyzes the S-box iterative output periodicity of AES encryption arithmetic. It proposes the S-box improved strategy and enhances resistance against cryptanalyze.
