摘　　要：介绍了高级加密标准AES一个新奇的代数性质,将AES非常简单的代数运算进行组合,出现了一系列恒定不变的代数结构,而且组合的代数运算具有非常小的代数阶数,这是目前其他的密码算法所不具有的代数性质,或许这种代数性质就是我们日后攻击AES的一个出发点。A novel algebraic property of advanced encryption standard （AFt） is introduced in this paper. It employed special algebraic properties of its primitive operations by using simple algebraic operations with known properties, and an invariable algebraic property is found. The combined operation has very low algebraic order, which does not exist in other cipher algorithm. The interesting, and unexpected algebraic properties may lead to a new attacking field in the future.
