Reliable and double-blind IP covert timing channel
Zhao-jun BO · Journal of Computer Applications · 2012
To solve the problems that the existing IP covert timing channel needs to make an early agreement on the encoding scheme between the information and IP packet timing interval,and cannot dynamically the double-blindly adjust the encoding scheme according to the network transmission quality in the process of sending and receiving,a double-blind dynamic adjustment strategy to negotiate IP covert timing channel encoding scheme was proposed.By segmenting the network environment and depending on the dynamic network environment,the strategy selected the default encoding scheme,and achieved double-blind dynamic adjustment of encoding scheme between sender and receiver.In order to verify the reliability of strategy,the experimental environment of covert timing channel was constructed.The results show that the proposed method can achieve double-blind dynamic adjustment between sender and receiver.
