混沌系统在网络保密通信中的应用方法

The Application of Chaotic System in Network Secure Communication

混沌保密通信是当今研究信息安全的热门课题之一该文就混沌系统应用于保密通信的基本理论．编码方式和密钥等内容作一简要讨论，并采用一次一密密码机制，用Lorenz系统的混沌输出作为密钥对文本文件进行加密和解密。这种一次一密加密方式具有很强的抗破译性．

Chaotic secure communication is one of current researching hotspots of information security. We discuss the fundamental theory of chaos in secure communication, including encryption schemes and secret keys briefly. Then we propose an encryption scheme of one message to one secret key, where the secret key, as the chaotic output of Lorenz system, will applied to encrypt and decrypt the message. Comparing with common approaches, the security of this kind of encryption scheme is obvious.
