面对舰船数据链信息在加密传输过程中存在安全隐患问题，设计舰船数据链信息加密传输方法，提升舰船数据链信息安全性。将舰船数据链信息转化为可加密的比特流，通过SM4分组对称加密算法加密比特流，完成舰船数据链信息加密；通过封装加密后的舰船数据链信息多源数据包，进一步提升其安全性后，利用直觉模糊集评判舰船数据链信息传输环境，并根据评判结果选择信任值高的传输协议，完成舰船数据链信息加密传输。实验结果表明：该方法在信息置乱情况下的舰船数据链信息加密传输效果较好，未发生信息丢失情况，且信息位置与理想情况一致；可实现舰船数据链信息有效加密，且加密后信息抗干扰性较高。
In the face of the hidden danger in the encryption transmission of ship data link information, the encryption transmission method of ship data link information is designed to improve the security of ship data link information. The ship data link information is converted into an encrypted bit stream, and the bit stream is encrypted by SM4 symmetric encryption algorithm to complete the encryption of ship data link information; After encapsulating the encrypted multi-source data package of the ship data link information and further improving its security, the intuitionistic fuzzy set is used to evaluate the information transmission environment of the ship data link, and the transmission protocol with high trust value is selected according to the evaluation results to complete the encryption transmission of the ship data link information. The experimental results show that the encryption transmission effect of the ship data link information is good under the condition of information scrambling, without information loss, and the information position is consistent with the ideal situation; It can realize effective encryption of ship data link information, and the information after encryption has high anti-interference performance.
