基于音频密写的载密移动通信系统的设计与实现

摘要

For in the public mobile communication system to embed secret information is hidden transmitting design implementation issues,this paper based on audio steganography of stego mobile communication system hardware and software design of the scheme for detailed analysis of the proposed based on DSP energy ratio adjusted the secret number according to the embedding/extraction algorithm. Experimental tests were carried out on the auditory similarity and robustness of the whole system. The results show that the system is able to realize the hidden and reliable transmission of the secret information in the mobile communication network.%针对在公共移动通信系统中嵌入秘密信息进行隐匿传输的设计实现问题，本文对基于音频密写的载密移动通信系统的软硬件设计方案进行详尽的分析，提出了基于DSP的能量比调整秘密数据嵌入/提取算法。对于整个系统的听觉相似性和健壮性进行了实验测试。结果表明系统能够很好地实现以语音为载体的秘密信息在移动通信网络中的隐蔽、可靠传递。
