摘　　要：提出了一种基于Lorenz模型的混沌调制的保密通信系统,通过将传统加密技术采用的扩展密钥思想用到混沌数字加密中去。给出一个秘钥,利用逻辑斯蒂映像格子和位操作替代加密秘钥产生一系列扩展秘钥。该操作使系统对秘钥值更灵敏,实现了Lorenz混沌加密系统的高保密性。This paper presents a secure communication system based on sporadic synchronization in a chaotic Lorenz system. The scheme applies the expanded key operation developed in the conventional cryptography. It give a secret key, some expanded keys are generated by using a Logistic map and the secret key is substituted with the expanded keys in encryption procedure. The operation can make the system more sensitive to the key value. Some numerical results are given and the security of the communication system is discussed.

关 键 词：洛伦兹系统 保密通信 扩展秘钥
