基于混沌的分组密码置换网络的设计
Design of Block Cipher Substitution Network on Chaos
文章利用混沌序列的遍历性，给出了一种分组密码置换网络的设计，并对混沌序列的遍历性和置换网络的时间复杂度做了分析。计算机模拟结果显示，混沌分组密码置换网络具有复杂性高、抗破译性强的优点，可以增强信息系统的安全性。
In this paper, a design of block cipher substitution network is presented by use of the ergodic theory of chaos. The ergodic theory of chaos and the time complexity of substitution network is analyzed. The computer simulation result shows that the block cipher substitution network of chaos is highly complex and strong in anti-decipher .
