实现AES加密算法代数表现形式的研究

Study on algebraic representation of AES encryption algorithm

针对AES加密算法中相对代数描述较弱的缺点,文章提出一种用代数多项式的表示方法来实现对该加密算法的整体描述,主要通过构建部分变换模块的多项式将其结合起来形成多项式环,从而构建整个AES加密算法的代数多项式。

Aiming at the weakness of relative algebra in AES encryption algorithm, this paper proposes a representation method of algebraic polynomial to realize the overall description of the encryption algorithm, which is formed polynomial ring by combining polynomial of partial transformation modules to construct the algebraic polynomial of the entire AES encryption algorithm.
