Nowadays, the intelligent transportation system (ITS) has developed prosperously all over the world. As a key technique in ITS, vehicular ad-hoc network (VANET) supports fast transmitting while bringing security problems simultaneously. To ensure efficiency, those unprotected data transmitting at a high speed can be easily eavesdropped on or forged, which will badly damage the ITS. To authenticate the identities of the vehicles in VANETs, signatures with certificates are often employed in historical research, but seldom study discusses the protection of generated data or mutual authentication between participants in VANETs. In order to tackle the problems above, we propose a new mutual authentication scheme for VANET where the private data can be kept away from attackers. In our scheme, the corresponding manager of each region can deal with the dynamic information of vehicles. The security analysis is also carried out and shown to emphasize the reliability of the scheme, such as anonymity, unlinkability and resistance to replay attacks, etc. Besides the resistance to different attacks, the real-time information secrecy can also be protected in our scheme, which is not achieved in the compared schemes. Moreover, the performance evaluation and simulation with NS-3 show that the packet delivery ratio reaches over 99% in most of the application scenarios, which proves that the scheme is efficient and practical.

VANET 中提供车辆匿名性和跟踪的相互认证方案

如今,智能交通系统(ITS)在全球范围内蓬勃发展。作为ITS中的一项关键技术,车载自组织网络(VANET)在支持快速传输的同时也带来了安全问题。为了保证效率,那些高速传输的不受保护的数据很容易被窃听或伪造,这将严重损坏ITS。为了在 VANETs 中验证车辆的身份,历史研究中经常使用带有证书的签名,但很少有研究讨论生成数据的保护或 VANETs 参与者之间的相互身份验证。为了解决上述问题,我们提出了一种新的 VANET 相互认证方案,其中私有数据可以远离攻击者。在我们的方案中,每个区域对应的管理者可以处理车辆的动态信息。还进行了安全分析,强调了方案的可靠性,如匿名性、不可链接性和抗重放攻击等。除了抵抗不同的攻击外,我们的方案还可以保护实时信息的保密性,这在比较方案中没有实现。并且,NS-3的性能评估和仿真表明,在大部分应用场景下,包的投递率都达到了99%以上,证明了该方案的高效性和实用性。除了抵抗不同的攻击外,我们的方案还可以保护实时信息保密,这是比较方案中没有实现的。并且,NS-3的性能评估和仿真表明,在大部分应用场景下,包的投递率都达到了99%以上,证明了该方案的高效性和实用性。除了抵抗不同的攻击外,我们的方案还可以保护实时信息保密,这是比较方案中没有实现的。并且,NS-3的性能评估和仿真表明,在大部分应用场景下,包的投递率都达到了99%以上,证明了该方案的高效性和实用性。
