摘要

针对迭代分组密码ＳＡＦＥＲ的缺陷，本文在变形ＳＡＦＥＲ［３］的基础上构造了两类分组密码，它们的结构与ＳＡＦＥＲ相象，复杂度略高于ＳＡＦＥＲ，具有加解密相似性，更好的扩散特性和更强的抗差分攻击的能力．

Abstract

Two block ciphers are constructed according to weakness of SAFER.Their structures are like SAFER with complexities a little higher than SAFER

and have encryption decryption similarity

better diffusion features and stronger ability against differential attack.
