数字签名的车联网安全体系架构设计研究

Research on the Design of Digital Signature Security Architecture of Internet of Vehicles

车联网构建了“车-云-路-人”的互联传输体系,而非法网络入侵和攻击使得车联网多通信场景存在巨大的安全隐患。基于数字签名技术设计了车联网安全体系架构,对云端、路侧设施端、移动终端、车端4个部分的架构进行了设计,同时搭建了数字签名的车联网安全架构。通过所设计的车联网安全体系架构,为车联网终端身份认证安全性提供了保障,确保了车联网的安全。

The Internet of Vehicles(IoV)constitutes an interconnected transmission system of“vehicle-cloud-road-human”.However,illegal network intrusions and attacks cause huge security risks in multiple communication scenarios of IoV.Based on the digital signature technology,an IoV security architecture model was designed,which incorporated the cloud,roadside facilities,mobile terminals and vehicle terminals and enabled digital signature.The designed IoV security architecture guarantees security for identity authentication of IoV terminals and ensures security in IoV.
