| Summary: | Characterized by decentration, anonymity, strong robustness and tamper resistance, blockchain accompanied by digital currency is a natural carrier for building the covert communication channel.First, the definition and development history of the network covert channel, the framework of blockchain technology and the traditional network covert channel were introduced and the advantages of the channel in the blockchain were given.Thus, the channel in blockchain was classified on the basis of transaction address, signature algorithm, smart contract and P2P broadcast mechanism.The merits and demerits were analyzed in terms of crypticity, transmission efficiency, and communication costs.Lastly, problems and the future research direction of the network covert channel in blockchain were presented. |
