对G．723．1高码率编码语音中进行压缩域信息隐藏的性能分析

近年来,基于混沌理论的保密通信和数据保密得到广泛、深入的研究,提出了许多基于混沌理论的混沌加密算法,但这些算法缺乏可靠的安全性和鲁棒性.本文在对文献[1]提出的一种在语音混沌保密通信过程中进行信息隐藏方案的分析中,通过对G.723.1高速率编码语音中适合进行压缩域信息隐藏的码位性能分析和仿真实验,进一步证明了文献[1]方案的有效性和安全性等特点.

Performance Analysis of Using G.723.1's High-rate Codes to Hiding Information in Packed Communication System

In recent years,a growing number of chaos encryption algorithms based on chaos theory have been proposed, many of them fundamentally flawed by a lack of robustness and security.In this paper,we propose a novel feedback for the features of G.723.1's high-rate codes to achieve an approach that hides the information in chaos-based secure com- munication system by sending information in the less significant bytes of the coded audio data.The result of experiment proves that the system mentioned in literature[1]i...
