摘要
信息隐藏这门新兴的技术不同于传统的密码学技术,信息隐藏的意义就是将密文信息秘密地隐藏于另一非机密的文件内容中。本文利用混沌学的己有成果,在总结现代密码学理论的基础上,分析了目前信息隐藏技术的理论和各种方法,提出了基于混沌的信息隐藏算法。基于混沌的音频信息隐藏算法是把密文音频经过混沌加密后,将其双声道嵌入到载体音频的双声道中,其抗攻击能力和隐藏能力很强,提取的密文音频质量良好。仿真结果表明该算法是有效的和可行的。
Based on the summarization of modern cryptographic theory, this paper uses the achievements of chaos to analyze the theory and techniques of information hiding . The algorithm of audio information hiding , which bases on chaos, is embed the double-channel audio of audio cipher text into one of the audio carriers. This algorithm has strong ability of anti-attack and concealment, and also it makes cipher text which has good audio quality. The results of emulation indicate this algorithm is available and feasible.
