Anonymous Batch Authentication Scheme in Internet of Vehicles for WAVE Security Services

Abstract

As a typical representative of the Internet of Things,the Internet of Vehicles plays an important role in intelligent transportation,not only providing vehicles with a variety of online services,but also reducing the risk of accidents for drivers.However,a large number of sensitive information such as vehicle location and route are generated in the communication process of Internet of Vehicle networks.How to improve the anonymity of vehicle identity in the authentication service is a research hotspot in the field of Internet of Vehicles security.In this paper,an anonymous authentication scheme based on a batch authentication algorithm is proposed,which extends the anonymous authentication methods for IEEE WAVE security services through anonymous credentials,zero-knowledge proof and other technologies,and provides a method to recover identity through a trusted third party.Experimental results show that the computational cost of the scheme is better than that of the partial comparison scheme when the number of batch validated signatures exceeds 11.Besides,the optimal cycle of batch verification in BSM application of DSRC and vehicle near field payment application is also analyzed.
