摘要
车联网(Internet of vehicles,IoV)正在为车辆用户提供更高效的数据通信服务。在大数据环境下,车辆用户身份信息的可用性使得车辆用户的安全成为一个重要问题。如果用户的身份信息被泄露,可能会导致他的行程被追踪,甚至造成生命危险。因此,实现车辆的匿名认证成为车联网亟需解决的问题。此外,及时处理大量数据也是一项复杂的任务。聚合签名(AS)可以将任意多个签名聚合成一个签名,大大提高了数据的处理速度。为此,笔者设计了一个适用于车联网的无证书强匿名的聚合签名(CL-SAAS)方案,并在随机预言模型下证明了该方案的匿名性和不可伪造性。目前,大多数关于匿名性的CL-AS方案只能抵抗来自第一类敌手的攻击,而该方案可以抵抗超级敌手A(A同时具有A_(1)和A_(2)的能力)的攻击。最后,方案与其他相关方案进行比较,结果表明该方案更高效,更适合于车联网。
Internet of Vehicles(IoV)is contributing more to the vehicle users for providing data communication services efficiently.Security of vehicle user is to be considered as an important issue due to their identity information availability in the big data environment.The leakage of the user’s identity information may cause all his whereabouts to be tracked and even cause life danger.Therefore,achieving anonymous authentication of vehicles has become an urgent problem for the IoV.Moreover,processing large amounts of data in a timely manner is also a complex task.Aggregate signature(AS)can aggregate signatures on disparate messages from disparate users into a single signature,which greatly improves the speed of data processing.For these all purposes,a certificateless strong anonymous aggregate signature(CL-SAAS)scheme for the IoV was designed.The proposed scheme then was proven to be anonymous and unforgeable.Most CL-AS schemes about anonymity can resist only the attack from Type I adversary,while our scheme can resist the attack from a Super adversary A(A has the capacity of both A_(1) and A_(2)).Finally,the proposed scheme was compared with several related schemes,and the results show that the proposed scheme is more efficient and suits for the IoV.
