通讯技术被称为世界经济和军事的生命线 ,而通讯中的保密技术则是核心技术之一 .任何这方面的新发现及其高科技的进展都必然引起世界各国的关注和重视 .由于混沌控制和混沌同步在 2 0世纪 90年代取得了突破性进展 ,迄今利用混沌进行秘密通讯成为国际上的一个热点 .现在混沌保密通信大致分为三大类 :第一类是直接利用混沌进行秘密通信 ;第二类是利用同步的混沌进行秘密通信 ;第三类是混沌数字编码的异步通信 .混沌保密通信为国际高新技术的发展提供了一个新的生长点 .目前已经提出了同步混沌通信三大保密技术 :混沌遮掩、混沌调制和混沌开关技术 .现着重综述近几年来混沌同步三大保密技术的主要进展 ,比较可能实现的十几种保密通信方案 ,分析题目的优缺点及其应用研究概况 .最后 ,给出混沌保密通信研究中保密技术的应用展望 .
Communication technology is called the lifeline of the world economy and military, and the confidential technology in communications is one of the core technologies.New discovery in this area and its high-tech progress are bound to attract the attention of all countries in the world.As a result of chaos control And chaotic synchronization made breakthrough progress in the 1990s, so far the use of chaos for secret communication has become a hot spot in the world.Current chaos secure communication can be divided into three broad categories: the first category is the direct use of chaos for secret communication; The second category is the use of synchronous chaos for secret communication; the third category is chaotic digital coding asynchronous communication.Chaotic secure communication provides a new growth point for the development of international high-tech.At present, three chaos communications have been proposed Technology: chaos masking, chaos modulation and chaos switch technology.Currently, the author summarizes the main progress of the three security technologies of chaos synchronization in recent years, more than a dozen kinds of secure communication schemes that can be realized, analyzes the advantages and disadvantages of the topics and the general situation of its application research. Finally, the application prospect of confidential technology in the research of chaos secure communication is given.
