| Abstract: | In order to meet the increasing demands for information transmission with highconfidentiality requirements, it is urgent to propose new covert anonymous communication methods. Covert Anonymous communication technology needs to meet the performances including security and hiding rate. At the same time, blockchain technology is characterized by decentralization, anonymity, traceability and distributed accounting. Bitcoin is the most well-known and popular blockchain currency application. Therefore, this paper proposes to use Bitcoin''s P2P network broadcasting and transaction mechanism to construct BDTX (Broadcast-Transaction) secret channel, use Bitcoin node connection mechanism to construct the ADDR (Version-ADDR) secret channel. Two kinds of secret channels are introduced in detail, and the security, hiding rate and real-time performance of the two hidden channels are analyzed. The security of the two hidden channels has been improved compared to the traditional IP network covert channels. |
