摘　　要：激光雷达网络电子通讯作为当前关键通讯技术之一,随着其应用范围的不断扩大,面对的安全风险程度也随之增加,导致电子通讯数据传输的安全性无法得到有效保障。因此,本文提出一种基于对称加密的激光雷达网络电子通讯数据安全传输方法研究。该方法通过引入对称加密算法,搭建激光雷达网络电子通讯数据安全传输框架。在该框架下,电子通讯数据经过数据处理、字节代换、行移位、列混淆与轮密钥添加等环节进行加密,同时确定密钥扩展模式。解密过程则通过密文处理、逆向行移位、逆向字节代换、逆向列混淆与逆向轮密钥添加等环节完成,从而实现电子通讯数据的安全传输。实验结果显示:应用提出方法获得的电子通讯数据安全传输时间最小值为1 s,电子通讯数据传输丢失率最小值为0.6%,充分证实了提出方法应用性能较佳。As one of the current key communication technologies,LiDAR network electronic communication faces an increasing level of security risks as its application scope continues to expand,resulting in the inability to effectively guarantee the security of electronic communication data transmission.Therefore,this article proposes a secure transmission method for electronic communication data in LiDAR networks based on symmetric encryption.This method introduces symmetric encryption algorithms to build a secure transmission framework for electronic communication data in LiDAR networks.Under this framework,electronic communication data is encrypted through data processing,byte substitution,row shifting,column obfuscation,and round key addition,while determining the key extension mode.The decryption process is completed through ciphertext processing,reverse row shifting,reverse byte substitution,reverse column obfuscation,and reverse round key addition,thereby achieving secure transmission of electronic communication data.The experimental results show that the minimum secure transmission time of electronic communication data obtained by the proposed method is 1 second,and the minimum transmission loss rate of electronic communication data is 0.6%,fully confirming that the proposed method has better application performance.
