摘要:智能交通服务是VANET领域研究的一个热点方向,但这方面的许多应用并没有考虑存在的安全问题。分析用手机软件叫车存在的安全隐患,利用基于属性的密码技术和自认证公钥密码技术,设计一个VANET中保护乘客隐私的安全叫车协议。安全性分析和仿真实验结果表明,该协议在保证使用效率的前提下,安全性得到了极大的提高。
Intelligent transportation service is a hot research direction of VANET, but many security issues in these applications were ignored. The security risks existing in taxi hailing using applications in smart mobile phone are analyzed, and a privacy-preserving taxi hailing protocol in VANET is designed by using the attribute-based encryption and self-certified signature. Security analysis and simulation results show that the protocol can deal with these security problems without affecting the efficiency.
