【摘要】 为提高车辆假名证书颁发的安全性,减少假名证书的颁发延迟,探讨一种基于代理机制的假名证书颁发策略——APCI,重点研究了CA系统的初始化、RSU代理的授权;利用RSU代理实现车辆假名证书的跨区域申请与吊销;采用短群签名与双线性对等技术实现了RSU代理的安全授权及假名证书的安全颁发.仿真实验结果和分析表明了此方法是有效的,可以提高车辆假名证书颁发的安全性、减少假名证书的颁发延迟.更多还原

【Abstract】 In order to improve the issuing security of pseudonym certificate to On-board Units(OBU),and reduce the issuing delay of pseudonym certificate,apseudonym certificate issuance policy(APCI)based on agent is explored in this paper.The main work focuses on the initialization of Certification Center(CA)system,authorization of RSU agent.Using RSU agent to achieve cross-regional application and certificate revocation of vehicle pseudonym,and achieving security authorization of RSU agent and security issuing of pseusonym certificate of OBU based on the short group signature and bilinear pairing technologies.According to the simulation results and analysis,the proposed policy achieves secutity issuing of pseudonym certificate to vehiches and reducing the issuing delay of pseudonym certificate.更多还原
