嵌入式系统下混沌加密算法研究

Research on Chaos Encryption Algorithm Based on Embedded System

随着移动终端的快速发展,信息传输的安全问题越来越受到人们的重视。科学界在对混沌特性不断探索中,发现将有效通信信号附加到混沌信号里是实现保密通信比较可靠的方法之一,被加密后的通信数据即便被截获,也很难被破译。本文主要从一种新的混沌电路模型入手,分析研究在嵌入式系统环境下实现通信信号加密的可行性,为实现嵌入式系统下的数据信息加密奠定基础。

With the rapid development of mobile terminals, more and more attention has been paid on the security of information trans-mission. In the continuous exploration of chaotic characteristics, the scientific community found that adding effective communication signals to chaotic signals is one of the reliable methods to realize secure communication. Even if the encrypted communication data is intercepted, it is hard to be deciphered. This paper starts with a new chaotic circuit model, analyzes the feasibility of encryption of communication signals in embedded system, and lays the foundation for the realization of data encryption in embedded systems.
