Abstract: S-box(Substitution box) is an important component in the block cipher.On the basis of studying the performance indices of S-box,a method for constructing S-box based on spatiotemporal chaos is proposed.Simulation tests show that a set of S-boxes with high cryptographic properties can be obtained according to this method,which is very helpful to design block cipher.

Key words: Substitution box, chaos, block cipher, information security

摘要: 置换盒又被称为S盒,是分组密码中常采用的重要部件。在分析S盒性能评价指标的基础上,提出了一种基于时空混沌的S盒产生方法。仿真测试表明根据该方法,可以产生一批具有良好性能的S盒,为开发新的分组密码算法奠定了很好的基础。
