摘　　要：为满足舰船在广域网环境的安全通信需求,提出广域网环境中舰船通信网络信息安全传输方法。基于云计算技术构建具备信息调度的舰船通信网络信息安全传输模型,并针对舰船通信广域网环境存在的来自不同方向的通信干扰源、信号衰减和噪声干扰,结合噪声消除算法进行舰船通信网络信息传输抗干扰设计,降低外界干扰影响;针对舰船通信广域网环境中实时信息在传输过程中面临的攻击、窃听、截取等多种安全威胁,采用双混沌互反馈加密方法完成舰船通信网络传输信息加密,保障信息在广域网环境下安全传输。实验结果表明,该方法可显著提升舰船通信速率,在不同干扰类型下均表现出良好的抗干扰性能;加密后信息可成功掩盖原始数据分布特征,保障传输信息安全性。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 realtime 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.
