VANETs中保护隐私的认证协议研究与进展

认证性和隐私性是车辆自组织网络（VANETs）中影响安全通信和个人隐私的关键问题：既要保证车辆之间和车辆与路边设施之间的安全认证通信,又要适当保护与车辆相关的信息的隐私性。文章将围绕隐私保护前提下的认证理论和核心技术问题,分析现有研究进展与成果,提出一些适合VANETs特点的研究方法和值得进一步研究的问题与方向,以期获得VANETs中保护隐私的认证新概念、新模型;探索保护用户隐私的安全匿名新方法,平衡认证与隐私保护中的矛盾对立,为VANETs的安全服务奠定理论基础、提供技术储备。

Privacy-preserving Authentication Protocols in Vehicular Ad Hoc Networks

Authentication and privacy are two critical concerns to secure communication and protect sensitive information in vehicu- lar ad-hoc networks （VANETs）. It is necessary to guarantee the information security and protect appropriately the vehicle-related infor- mation privacy between vehicles or between vehicles and roadside units （RSUs）. This paper considers privacy protection and the au- thentication theory with the related core technology by making use of new cryptographic methods, surveys the main previous privacy- preservation authentication protocols; addresses some new issues and new research direction. It is expected to develop a series of new authentication methods for protection of privacy which are adapted to the features of VANETs, improve greatly the theoretical foundation of VANET and provide with technical reservations for VANET security services.
