WIST:基于三维查找表的SM4算法新型白盒设
WIST:White-Box Implementation of SM4 Algorithm with Three-Dimensional Lookup Table
摘要
Abstract
As cryptographic attacks become more diverse,covert and destructive,cryptanalysts are assumed to have more power and capabilities than before,and are able to obtain the internal structure of the target cryptographic algorithms.In order to protect keys more effectively,a novel white-box implementation for SM4 algorithm is proposed based on three-dimensional lookup table,called WIST in this paper.The SM4 block cipher algorithm is expressed in nonsingular matrix of linear transformation;then the three-dimensional lookup table is designed to hide the key information,the input coding and output coding are used to confuse the lookup table.Meanwhile,the affine function is adopted as external coding,the white-box implementation for SM4 algorithm is completed,and the correctness of this algorithm is also verified.The efficiency analysis on WIST algorithm shows that it occupies moderate memory space and has high security.The security analysis on WIST algorithm shows that this scheme can resist BGE attack,MGH attack,side channel attack,linear attack and differential attack.This scheme can protect key information well in white-box attack environment.关键词
