丢失音频数据包隐写术：首次实用评估
Lost Audio Packets Steganography: The First Practical Evaluation
摘要：
本文介绍了第一个实验结果的IP电话为基础的隐写方法称为LACK（丢失的音频包隐写）。该方法利用了这样的事实，即在典型的多媒体通信协议（如RTP（实时传输协议））中，过度延迟的分组不用于在接收器处重构所传输的数据，即，这些分组被认为是无用的并且被丢弃。本文给出的结果是基于一个功能性的LACK原型得到的，并显示了该方法对语音传输质量的影响。还计算了不同IP电话编解码器的可加密隐写带宽。
英文摘要：
This paper presents first experimental results for an IP telephony-based steganographic method called LACK (Lost Audio PaCKets steganography). This method utilizes the fact that in typical multimedia communication protocols like RTP (Real-Time Transport Protocol), excessively delayed packets are not used for the reconstruction of transmitted data at the receiver, i.e. these packets are considered useless and discarded. The results presented in this paper were obtained basing on a functional LACK prototype and show the method's impact on the quality of voice transmission. Achievable steganographic bandwidth for the different IP telephony codecs is also calculated.
