With the continuous iteration of network attack methods and the increasing intensity of attacks, a large number of communication systems are facing the threat of network attacks. There are still risks in the existing secure and covert communication systems in the network environment, facing issues such as easy detection of communication channels, easy tracking of communication parties, and low communication efficiency. This poses a great challenge for establishing a secure, private, and efficient communication system. Blockchain, as a new technology system with decentralized architecture, has the characteristics of decentralization, tamper resistance, and anonymity. It can effectively solve the problems of traditional data covert transmission technologies that are easily blocked by interference, low reliability, and easy to detect and track, and achieve non directional sending and unintentional receiving of covert transmission. Therefore, this article proposes a blockchain based data covert transmission scheme. This scheme utilizes the characteristics of blockchain to achieve covert communication behavior and identity, enhance the anti-interference and reliability of network covert channels, and improve the efficiency of data covert transmission. The relevant test results have proven that our scheme can effectively improve the security of data covert transmission.
