受到复杂电磁环境干扰，舰船网络拓扑结构频繁变化，信息加密及传输的机密性较低，严重威胁舰船关键业务的正常运行。为此，开展复杂电磁环境干扰下舰船网络信息安全传输方法研究。先应用MapReduce并行处理模型，融入混合混沌映射高效加密舰船网络信息，得到舰船网络信息密文；然后构建安全传输通道模型，以克服复杂电磁环境导致网络拓扑结构频繁变化的干扰；最后将制定的传输协议引入该通道中，实现舰船网络信息的安全传输。实验结果表明，在复杂电磁环境干扰下，该方法面对多种常见攻击仍可安全传输舰船网络中的各类信息，且信息丢失量极低，应用效果较好。
Affected by complex electromagnetic environment interference, the topology of ship networks frequently changes, and the confidentiality of information encryption and transmission is low, posing a serious threat to the normal operation of critical ship services. To this end, research is being conducted on secure transmission methods for ship network information under complex electromagnetic environment interference. Firstly, the MapReduce parallel processing model is applied to efficiently encrypt the ship network information by incorporating mixed chaotic mapping, and obtain the ciphertext of the ship network information; Then, a secure transmission channel model is constructed to overcome the interference caused by frequent changes in network topology due to complex electromagnetic environments; Finally, the developed transmission protocol will be introduced into this channel to achieve secure transmission of ship network information. The experimental results show that under complex electromagnetic environment interference, this method can still safely transmit various types of information in ship networks in the face of multiple common attacks, and the amount of information loss is extremely low, with good application effects.
