Abstract

The communication method in which both parties could modify certain types of shared resources without attracting the attention of other users is called covert communication. Generally, researchers believe that blockchain, as a distributed storage database that can still guarantee security in an unreliable network environment, has excellent characteristics such as open, decentralized, untrusted, anonymous, tamper prevention, traceability, and contract execution automation. More and more studies have applied it to covert communication technology. Due to the different transaction mechanisms of various blockchain systems, schemes based on system mechanisms are usually designed for a specific transaction mechanism of a blockchain, making the scheme more covert. The blockchain covert communication scheme based on transaction mechanism designed in this paper mainly utilizes the Bitcoin transaction mechanism in the Bitcoin system. The transaction parties generate addresses as input addresses through pre negotiated keys, construct invalid transactions through transaction withdrawal mechanisms, embed secret information in invalid transactions, and make them undetectable on the blockchain network. The receiver obtains information about invalid transactions through the negotiated keys, Decrypting and obtaining secret information completes the communication process of covert communication.
