车联网(IoVs)广泛用于获取车辆和道路状况等信息,但是这些信息都是在公共信道中进行传输,所以最重要和关键的要求之一就是在严格延迟要求下的数据安全.其中,认证是解决数据安全最常用的方法,但是由于车联网的资源受限和对延迟敏感等特点,车辆认证需要在一定的消耗和延迟内完成.然而,现有方案容易遭受物理、伪造和共谋等攻击,同时也产生了昂贵的通信和计算成本.该文提出一种基于物理不可克隆函数(PUF)的车路云协同轻量级安全认证方案.所提议方案采用轻量级的物理不可克隆函数作为车联网实体的信任保证,抵御攻击者对实体的物理和共谋等攻击;采用车路云协同的架构,在经过可信机构(TA)认证的路边单元(RSU)上完成认证运算,大大减轻了TA的计算压力,并将挑战响应对(CRPs)的更新应用到假名的构造更新中,保护身份和轨迹隐私的同时也能在身份追踪阶段披露恶意车辆身份.在实际场景的模拟实验中,通过与其它方案进行比较,表明该方案更加安全和高效.
A Lightweight and Provably Secure Authentication Protocol for Internet of Vehicles Using Physical Unclonable Function
The Internet of Vehicles(IoVs)is widely used to obtain information about vehicles and road conditions,which is transmitted in public channels.Hence,the most important requirement is the data security.Because of characters of IoVs,we need to make it keep in a strict delay.Authentication is a common method to solve it.Due to limited resources and delay sensitivity of IoVs,vehicles must complete authentication within appropriate resources cost and delay.However,existing schemes are prone to physical,forgery and collusion attacks,and moreover,they are computationally heavy.Therefore,a lightweight security identity authentication scheme for vehicle-road collaboration is proposed in this paper,which utilizes lightweight Physical Unclonable Function(PUF)as the trust root of entities to resist physical and collusion attacks;Besides,most of computations are offloaded to Road Side Units(RSUs)certified by Trusted Authority(TA)through the vehicle-road-cloud collaboration architecture;In addition,vehicular pseudonym construction and update include Challenge-Response Pairs(CRPs),which are utilized to protect identity and trajectory privacy and expose malicious vehicular identities in identity tracking phase.Furthermore,there are formal and informal security analyses to prove our scheme is secure.Finally,the simulation experiment shows our scheme is more secure and efficient than other schemes in real scenarios.
