Research on Underwater Bionic Covert Communication

Due to the particularity of the underwater environment, underwater acoustic communication is an inevitable choice for underwater wireless sensor networks (UWSNs) communication. In recent years, with the development of underwater acoustic communication technology, the communication rate and communication quality of underwater wireless sensor networks have been greatly improved. At the same time, it has proposed the protection of the concealment of underwater equipment and the safety of underwater acoustic communication. New requirements. This paper reviews and summarizes the development status of underwater bionic covert communication. The analysis shows that the underwater bionic covert communication method using marine mammal vocalization as an information carrier has great advantages, which points out the direction for the research of underwater sensor network security communication.
