摘要:

提出了一种基于混沌数字流的信息隐藏技术,利用加密算法和混沌系统的类随机性特点 构造出一种混沌数字流,借助于该数字流可以在收发双方进行各种信息的隐藏传输,由于混沌数字流 的格式只对收发双方公开并且混沌系统有确定的动态方程,因此,该方法安全性较高,隐藏信息量大。 最后,给出了该方案的实现算例。

Abstract:

A novel scheme for information hiding based on chaos digital stream was proposed, a kind of chaos digital stream which can be used to hide various information between receiver and transmitter was constructed by means of encryption and randomness of chaotic dynamic systems, as the format of stream is open only to receiver and transmitter and chaotic systems have definite equations, the scheme is safer, having large capacity of hiding. At last, an example was given to account for the scheme.

Key words:  information hiding, chaotic digital stream, encryption algorithm
