摘要
对G.723.1语音编解码算法和混沌系统的特点进行分析,提出了一种在语音混沌保密通信过程中进行信息隐藏的方案,利用编码语音数据的低有效位安全传递保密信息。试验证明,该方案可以实现密钥的隐蔽传输和实时更新,进一步提高通信过程的抗破译能力。能够广泛应用于各种需要保密通信的场所,防止遭到窃听,保证信息安全。
For the features of G.723. 1 and chaos-based system, this paper introduces an approach that hides the information in chaos-based secure communication system by sending information in the less significant bits of the coded audio data. Experimental result proves that hidden transfer and real-time update of the key makes the system more secure. It can be widely used in places where secure communication is needed to avoid wiretapping and guarantee security.
