一种用于汽车充电的轻量物联网通信协议

A Lightweight Internet of Things Communication Protocol for Car Charging

新能源电动汽车充电支付是未来物联网金融服务的重点支付场景之一。从当前电动汽车基于车架号(VIN)无感支付场景出发,分析指出现有通信协议存在明文传输的安全问题,且物联网场景下不具备高效大规模组网能力,设计了一种轻量级基于现代加密理论的可信物联网通信协议方案,并从灵活轻量和网络安全可信两个方面进行介绍,列举了轻量可信协议在智能充电业务中的应用案例,并完成了实验室原型系统验证,解决了机器与机器信息交互过程中的信息安全传输与身份认证问题,从而为物联网的自动化支付提供了更为安全有效的基础设施服务能力。

Charging and payment for new energy electric vehicles is one of the key payment scenarios for future internet of things financial services.In the senseless payment scenario of Vehicle Identification Number(VIN),this paper indicates that current communication protocols have security issues related to plaintext transmission,and do not have efficient large-scale networking capabilities in IoT scenarios.So we design a lightweight trusted internet of things communication protocol based on modern encryption theory,list application cases of lightweight trusted protocols in intelligent charging services,and complete laboratory prototype system verification.It solves the problem of information security transmission and identity authentication during the information interaction between machines,providing a more secure and effective infrastructure service capability for automated payment of the internet of things.
