摘要 针对基于传统的密码算法保密电话数据加密存在的缺陷,提出一种基于成对载波和混沌加密技术的保密电话解决方案。该方案用成对载波和回波抵消的体制保证语音信号的安全,用密码的方法保证整个数字传输通信系统的安全性,因此,电话系统保密性更高,实用性更强。 Aiming at the defects of secure telephone based on tradition cipher encryption,a solution was put forward,which based on paired carrier and chaotic encryption technology.This scheme uses offset paired carrier and echo system ensure the speech signal safety,this scheme uses cryptographic methods to ensure the safety of the whole digital communication system.Therefore,the telephone system is more secure,more practical.
