The existing covert communication method based on TCP/IP or HTTP often utilizes characteristics of protocol and hides extra data in specific fields of protocol header. Such a method leaves some obvious signatures. However, timing-based covert communications have some kind of traffic pattern. We propose a censorship-resistant covert communication protocol based on Web communication behavior, which combines dynamic asymmetric communication and Markov model-based Web usage prediction. In this paper we focus on covert communication protocol, prototype system, and security of the protocol. The test results show that our method has high performance and safety.
