中文摘要:
      车联网是一个拓扑结构快速变化的分布式自组织网络,因此提供迅速及时的车辆接入服务尤为重要。针对该问题,文章采用基于双离散对数的知识签名技术设计了一种在车联网中进行车辆身份的快速认证协议。车载单元在进入车联网时向路旁辅助单元请求入网,并通过基于知识签名的协议算法证明其知道系统密钥,从而实现车辆与路旁单元的快速接入认证服务,本方案具有认证快速、通过迅速,能快速适应高速实时通信的创新特点。仿真实验结果表明,同多个基于群签名技术的身份认证方案比较,在认证时间消耗上,本协议比Zhao Z等人的方案节约了18.92%,尤其是在当车辆规模在200个以下时,本方案在通行认证效率、通行效率等性能上优于Zhao Z、YOON HY 、WU TY等人的方案。
英文摘要:
      The vehicular Ad hoc network (VANET) is a distributed self-organizing network with rapidly changing topology, so it is particularly important to provide fast and timely vehicle access services. For this problem, this paper designs a fast authentication protocol of vehicle identity based on Knowledge signature technology of double discrete logarithm. When the vehicle unit enters the VANET, it requests the roadside support units(RSU) to enter the network, and proves that it knows the system key through the protocol algorithm based on knowledge signature, so as to achieve the quick access authentication service of vehicle and roadside units, This scheme has the innovative characteristics of fast authentication, fast passing and fast adaptation to high-speed real-time communication. The simulation results show that compared with identity authentication schemes based on group signature technology proposed in this paper, this protocol saves 18.92% of the authentication time compared with Zhao Z''s scheme, especially when the vehicle scale is less than 200, this scheme is superior to Zhao Z''s 、YOON HY’s 、WU TY’s scheme in the performance of authentication efficiency and traffic efficiency.
