Study on Detection Algorithm of Complicated Covert Channel
Kong Jianshou · Jisuanji fangzhen · 2012
To solve the problem that different kinds of covert channels can not be detected by a particular detection algorithm,the working mode and characters of covert channel were analyzed,and then the detection algorithm based on density cluster was proposed.The algorithm could find not only different kinds of single covert channels but also complicated covert channels which were composed of several kinds of covert channels.In the simulation system,a complicated covert channel composed by five kinds of covert channels was implemented.The algorithm was used to detect the complicated covert channel.The detection results show that the algorithm can work well even the noise in the channel was about 20%.
