利用IDEA算法之MA—结构的对合置换

An Involution Permutation Based on MA-Structure In IDEA

利用国际流行的目前最安全的数据加密算法IDEA的核心构件MA—结构构造出了一种12 8比特长的对合置换 ,并对其进行了简要的分析 。

The paper constructs an involution permutation with 128 bits long by using the MA-structure in IDEA and simply analyses its properties. Finally, a sort of secret-key block cipher is constructed with the help of this involution permutation
