基于混沌的一次性口令认证的保密通讯

The one time password communication based on the chaotic system in the secure Network

如何更加有效地进行用户身份鉴别和信息保密,是网络安全的重要课题之一。本文讨论了在TCP/IP协议下网络通信的不安全因素,将Logistic映射产生的混沌序列作为载波,提出了一种改进型OTP的工作机制。该方法利用随机生成的混沌数列,采用C#语言T、CP/IP协议和面向对象程序设计方法,实现随机加密用户数据信息。通过仿真实验分析,该系统能有效抵抗系统识别攻击,且加密效果良好,非常适合于资源开销有限和实时性要求较高的安全通信场合。

To make authentication work and information security more effective is an important subject in the network safety.In this paper,the insecurity complication of a network system based on the TCP/ IP protocol were investigated,the chaotic sequence generated by Logistic map are used as the carrier,the working mechanism of one advanced One Time Password(OTP) is proposed.Chaotic random number is utilized,through using C# language,TCP/ IP protocol and the OOP method,the authors design the secure communication software by encrypting user datagram information.Simulation results show that the cryptosystem can resist attacking of system identification,and ciphertexts encryption effect is well.It is very fit those secure communication situations of resource restricting and high real-time requirement.
