In the modern society, the communication technology has great influence on the safe navigation of the ship.Especially in the modern ship communication network, the importance of navigation and equipment control information transmission to the whole ship network is self-evident. In order to meet the requirement of communication rate and confidentiality, this paper focuses on the encryption algorithm in the process of ship network data transmission. By combining chaos theory with encryption communication technology, efficient encryption communication is realized, and chaotic sequence generation algorithm is introduced. The implementation of encryption in data network is expatiated. The simulation results show that the proposed encryption algorithm can reduce the delay and improve the security of information transmission.
