Network covert channel is a communication technique that utilizes the redundancies of the network to transfer secret information. With the appearances of various covert channels, how to evaluate their performance is becoming an urgent need. There are two main contributions in this paper, one is the model of network covert channel and the other is an evaluation index and method based on analytic hierarchy process. In the last, five typical covert channels are used to verify the effectiveness of the proposed index and method. The example analysis verifies the effectiveness of the proposed index and method.
