一种无线语音混沌保密通信系统的设计与实现
Design and Implementation of a Wireless Speech Chaotic Secure Communication System
摘要
Abstract
In order to implement wireless transmission and decryption playback of the encrypted chaotic speech signals,based on the system hardware platform which is consisted of DSP chip TMS320VC5509A, radio frequency chip nRF24L01 and audio codec chip TLV320AIC23, the Euler algorithm is used to discretize the continuous Lorenz chaotic system for genetating chaotic digital sequences, which are used for encryption and decryption.The experiment of wireless transmission is performed on the encrypted speech signals, and the receiver can decrypt the encrypted speech signals.The witeless chaotic secure communication of speech signals is achieved.关键词
