Generally , it can be divided into three parts : the design of s - boxes based on chaotic systems ( fixed or dynamic s - box ) , the design of various block ciphers based on chaotic systems , and the application in digital watermark of chaotic ciphers 本文关于混沌分组密码及其应用的研究主要涉及下面三个问题:基于混沌系统的s盒设计(固定的和动态更新的s盒) ;基于混沌系统的不同类型的分组密码设计;混沌分组密码的在数字水印方面的应用。
