摘　　要：给出一种改进的罗仑兹混沌保密通讯电路系统。该系统利用耦合同步罗仑兹混沌电路进行数字信号的混沌遮掩传送,在发送端和接收端之间只需传送一个带有数字信息的混沌信号即可实现高质量保密传送信息。模拟实验表明:在接收端将信息检出经整形处理后可无失真地恢复所传送的数字信号,与Yn P Lookman T设计的电路相比,隐蔽性更好、电路更简单、实用性更强。The authors have presented a circuit system able to be used to secure communications with digital sig, nals masked by Lorenz chaos. Only one chaotic signal, which carries digital information, is needed to transmit to the receiver. Secure communication can be realized with high quality. Simulation experiment with transmission of digital information shows that the circuit system is stable and reliable; the information transmitted can be detected and accurately restored by the synchronous chaotic signal at the receiver.
