In order to meet the secure communication needs of ships in wide area network environments, a secure information transmission method for ship communication networks in wide area network environments is proposed. Based on cloud computing technology, a ship communication network information security transmission model with information scheduling is constructed. In response to the communication interference sources, signal attenuation, and noise interference from different directions in the ship communication wide area network environment, noise elimination algorithms are combined to design anti-interference measures for ship communication network information transmission, reducing the impact of external interference; In response to various security threats such as attacks, eavesdropping, and interception faced by real-time information transmission in the wide area network environment of ship communication, the dual chaos mutual feedback encryption method is adopted to encrypt the transmission information of ship communication network, ensuring the safe transmission of information in the wide area network environment. The experimental results show that this method can significantly improve the communication speed of ships and exhibits good anti-interference performance under different types of interference; The encrypted information can successfully mask the distribution characteristics of the original data, ensuring the security of the transmitted information.
