AES算法主要包括三个方面：轮变化、轮数和密钥扩展。本文以128为例，介绍算法的基本原理；结合C语言，实现高级数据加密算法AES（AES-128）。-AES algorithm mainly includes three aspects: round of changes, round number and key expansion. In this paper, 128 for example, introduce the basic principles of algorithm combination of C language, the realization of advanced data encryption algorithm AES (AES-128).
