IBE技术在V2X通信中的应用

Application of IBE Technology in V2X Communication

V2X(Vehicle to Everything)技术是智能网联汽车的一项关键技术,为解决在V2X通信过程中在满足隐私保护的同时实现安全性,欧美等国提出了基于PKI/CA的认证体系,这种解决方案对通信证书发放中心的处理能力和性能要求较高,证书签发流程的复杂性无法满足车车、车路通信低时延的要求。为此提出了基于IBE技术的V2X通信身份认证体系,采用IBE服务器取代欧美方案中通信证书发放中心,由IBE服务器向通信参与方发放密钥用于身份验证,该认证流程相对简化,整体通信效率得到了优化。

V2X(Vehicle to Everything)communication technology is a critical technology of intelligent connected vehicle.In order to achieve identity authentication to the parties involved in communication while protecting privacy in V2X communication,some organizations in Europe and the United States have proposed a PKI/CA authentication system.This solution has higher requirement on processing capability and performance of the communication certificate issuing center.The process of issuing a certificate does not match the requirements of low latency communication.Therefore,this paper proposed the V2X communication authentication identity based on IBE technology,that used IBE server to replace the communication certificate issuing center of the European solution,and IBE server issue secrete key to the parties involved in communication for authentication.IBE technology is simplified in authentication process,and whole communication efficiency is optimized.
