一种基于递归图的网络时间隐蔽信道检测方法 (Approach Based on Recurrence Plot to Detect Covert Timing Channels)

The detection of covert timing channel is the foCUS of the research of covert channel,and it is very difficult. Entropy-based approach is the most effective detection approach.It can detect almost al the covert timing channels. However,Liquid is proposed soon after.It can effectively evade the entropy-based detection by smoothing the entropy. In this paper,a detection approach based on recurrence plot was introduced,and the detection approach can detect vari OUS covert timing channels including Liquid.
