Research on security of underwater sonar communication

Abstract： With the exploration and development of the ocean, the underwater network, especially the underwater communication technology, is gradually mature. Sonar is usually used for underwater communication, and underwater sonar communication channel is vulnerable to malicious attack because of its disadvantages such as low transmission rate, high bit error rate, high delay and narrow channel. Therefore, attention must be paid to the safety of underwater sonar communication. Aiming at the current situation that the security protection level of underwater sonar communication system is weak, considering the unique characteristics of underwater acoustic communication, the future development trend of underwater cipher equipment is summarized. Furthermore, from the point of view of protecting data confidentiality, a cryptographic prototype and a lightweight cipher algorithm are designed to demonstrate and verify the encryption technology of underwater sonar communication. The test results show that the cryptographic prototype with lightweight cipher algorithm is very suitable for the security protection of underwater communication and can meet the requirements of communication speed, which lays a certain research foundation for the future underwater sonar communication system to carry cryptographic system.
