摘要：

This paper takes the popular applications WeChat and Enterprise WeChat as examples and investigates the embedding of information in VoIP traffic for data transmission. Exploring the alterations in VoIP traffic characteristics under different vocal environments, this study proposes a covert communication method that transforms the traffic features from silent vocal states to noisy by modifying the length distribution of VoIP traffic. Experimental results demonstrate that this approach achieves channel bandwidths of up to 35kbps and 28kbps in the silent vocal environments of WeChat and Enterprise WeChat, respectively.
