Abstract

Aiming at the anonymity of vehicle identity and message authentication security problems in Internet of Vehicles information interaction. At present, many schemes are constructed by bilinear pairings, which have low computational efficiency, high communication cost and key escrow problem. This paper proposed a certificateless aggregated signature scheme suitable for Internet of Vehicles. The vehicle's key was jointly generated by the KGC and the vehicle, which avoided the problem of key escrow. This solution did not use a bilinear pairing operation, and supported aggregate verification. The signature length did not show an increasing trend with the increase in the number of vehicles. Under the random oracle model, based on the discrete logarithm problem on the elliptic curve, it proves that the scheme has signature unforgeability. Through performance analysis, the scheme has higher calculation efficiency and lower communication overhead.
