Abstract

Due to the sporadic alienation of the underwater sensor, the node deployment is very scattered, and the physical safety of the node is difficult to get guaranteed. Traditional solutions to ensure security encryption algorithms will increase energy consumption. The reliability of traditional encryption solutions based on difficult mathematical problems with difficulty mathematics issues is getting lower and lower. In order to ensure the secure transmission of communication data, a physical layer security solution is proposed. This scheme through the legal communication between the two parties to develop channel detection sequences, extract channel status information, obtain channel feature value, pre-process the feature value, and use the improved CQG algorithm to generate key. Finally, key negotiation and privacy enhancement are performed on the key. The simulation results show that compared with the traditional CQG algorithm, the improved CQG algorithm can make the key generation rate significantly improved when the key inconsistent rate is slightly reduced.
