摘要

隐蔽信道是一种传输网络协议中通常不允许的信息的手段。例如，协议中未使用或不重要的比特可以用来传输秘密消息。我们提出了一种新的技术来揭示网络中隐蔽信道的存在。该技术使用熵估计，不仅可以检测秘密消息，还可以估计其大小。

Steganalysis of Storage-based Covert Channels Using Entropy

A covert channel is a means of transmitting information that is not normally allowed in a network protocol. For instance, unused or insignificant bits of a protocol could be used to transmit secret messages. We present a novel technique to uncover the existence of covert channels in networks. The technique uses entropy estimates, and can not only detect secret messages, but also estimate their size.
