Abstract

Abstract

How the variable S-boxes would affect the security of the block cipher was studied and a new block cipher using random variable S-boxes was presented. A new encryption scheme based on such block cipher was put forward: the structure of the original encryption algorithm was kept, the S-box was taken as a variable and variable S-box was used instead of the primary one, which could increase the resistance against those known attacks. The security evaluation proves the scheme secure. Furthermore, a discussion on the improvement about the generation of the S-boxes and structure of the algorithms was given.
