摘　　要：针对传统物联网数据加密技术中设定的数据加密方式存在局限性,导致传输后信息丢包率较高且时延较长的问题,设计了基于光通信技术的物联网数据加密技术。首先构建物联网的拓扑结构,根据光通信传输特征优化物联网传输协议,对物联网的数据流匹配域进行更新,根据更新结果,结合数据密算法完成对网络中数据的映射加密,实现物联网数据加密。仿真结果表明,相对于传统数据加密技术,数据加密技术的信息传输后丢包率在1.6%以内,数据传输时延在0.5 s以内,具有良好的使用性能。Because of the limitations of the data encryption method set in the traditional data encryption technology of the Internet of things,resulting in high packet loss rate and long delay after transmission,the Internet of Things’ data encryption technology optical communication technology is designed. Firstly,the topological structure of the Internet of things is constructed. According to the transmission characteristics of optical communication,the transmission protocol of the Internet of things is optimised,and the data flow matching domain of the Internet of things is updated. According to the updated results,combined with the data encryption algorithm,the mapping encryption of the data in the network is completed to realise the data encryption of the Internet of things. The simulation results show that compared with the traditional data encryption technology,the packet loss rate of the data encryption technology is less than1. 6%,and the data transmission delay is less than 0. 5 s,which has good performance.
