摘要
近年来 ,在通信领域隐蔽通信技术正越来越受到重视 .本文提出了一种新的实时隐蔽通信算法 ,该算法利用了混沌序列具有容易生成、对初始条件敏感 ,以及具有白噪声的统计特性等特点 ,有效地解决了隐蔽通信技术的两个问题 :同步以及突发信息的接收 .
In recent years,covert communication techniques have become important gradually in communication fields.In this paper,a novel real-time covert communication scheme has been proposed.This method makes use of good properties of chaotic sequences,such as ease of generation,sensitive dependence on their initial condition and noise-like statistic characteristics.Two key problems,synchronization and receiving burst messages,have been solved effectively.Experimental results indicate that these techniques are very effective.
