提出了一种名为混沌多重交换和模拟退火 (CMSSA) 的有效算法，用于获得加密强度高的 8 x 8 S 盒。该方法基于混沌映射和模拟退火。此外，对生成的S盒还详细分析了双射性、严格雪崩准则、非线性、输出比特独立性准则和等概率输入/输出异或分布等密码学特性。数值分析结果表明，该盒子已经基本满足密码学强S盒的标准，可以有效抵抗多种攻击。 (c) 2006 年，爱思唯尔有限公司出版。
An efficient algorithm named chaotic multi-swapping and simulated annealing (CMSSA) for obtaining cryptographically strong 8 x 8 S-boxes is presented. The method is based on chaotic maps and simulated annealing. In addition, cryptographic properties such as bijectivity, strict avalanche criterion, nonlinearity, output bits independence criterion and equiprobable input/output XOR distribution are analyzed in detail for the S-box produced. The results of numerical analysis show that the box has nearly fulfilled the criteria for a cryptographically strong S-box and can effectively resist several attacks.
