摘要
在混合差分法基础上研究SARER-64系统密码分析的加速技术.建立了明文对选择策略,给出了限定字节密钥范围算法和错误密钥的快速剔除法.结果表明,运用加速技术可大大地加快密码分析速度.
Based on the combined differential method, the accelerating technique of cryptanalysis on SAFER-64 systems is investigated in this paper. The technique of plexertext pair selection, the algorithms of reducing the range of the byte keys, and the elimination of incorrect keys are presented . It is shown that the attacking on SAFER-64 systems is accelerated highly with these techniques through theoretical analysis and digital tests.
