基于车辆身份的车联网结构与安全

Security issues and system structure of internet of vehicles

对车联网安全研究进行了综述,没有逐一分析车联网应用场景的具体安全需求,而是着眼于车联网系统本身的特点,提炼出了当前发展中所存在的主要问题,进而厘清了车联网在不同发展阶段的概念内涵及网络架构;在明确的车联网概念与结构的基础上分析其安全问题,提出了以车辆身份认证为基础的三层安全体系结构,并以此结构为基础,分析了相关工作的进展。最后,指出了随着通信技术与数据服务能力的发展,车联网结构和安全研究的新领域。

Instead of focusing on concrete security requirements of each IOV applying scenario, the architecture characteristics of the IOV networking systems were summarized, and the main security problems were extracted by analyzing the connotation and network architecture of IOV in different development stages. Then an identity authen- tication based three-tier security architecture over the clearly analyzed concept and structure was proposed, and the related IOV security research with the view of the presented three-tier security architecture were surveyed. Finally, some new developments and progresses over security of IOV were presented.
