This channel used the number of IP packets sending in a fixed time window to transmit hidden message. To improve the bandwidth of RNCC, analyzed a new information encoding mechanism. Furthermore, proposed a new synchronization method, which was to solve the problem of time synchronization of the traditional IP covert timing channel, and to ensure the reliability of RNCC. The experimental results show that the capacity and robustness of RNCC is better than the traditional IP covert timing channel. %K IP covert timing channel %K network delay jitter %K encoding mechanism %K synchronization mechanism %K sending algorithm %K receiving algorithm
