混沌保密光通信技术在电力通信网中的应用
The Application of Chaotic Optical Communication in Electric Power Communication Network
摘要
Abstract
Chaotic signal has drawn much attention in secure communication for its characteristics of wideband,noise-like and long-term unpredictable.In this paper,chaotic optical communication is proposed to solve the secure problem of transmission in power communication network.We first study the traditional chaotic optical encryption scheme experimentally,and then in-vestigate the secure problems of chaotic optical communication in power communication network.The scheme of time delay concealment is proposed to solve the secure problem,while the time delay concealment is experimentally demonstrated.Moreo-ver,the security of chaotic optical communication is analyzed for parameter estimate attack,and the key space is proved to be enlarged significantly by analysis,which proves the difficulty of brute force attack,and ensures the transmission security in power communication network.关键词
