Abstract

With the development of the Internet of Things (IoT) and the intersection of electrification, networking and intelligence, the risks of vehicle operational safety, data security and network security are intertwined and overlapping, and the security situation is more complex and severe. Thumbur propose a certificateless aggregated signature for vehicular ad hoc networks (VANETs) to solve the authentication and efficiency problems in vehicular networks, and prove the unforgeability of the scheme based on the elliptic curve discrete logarithm problem. In this paper, we propose a new certificateless aggregated signature scheme based on this scheme and prove its security under the random prediction model. Finally, we compare and analyse the computational and communication efficiency of the scheme and show that the computational and communication costs of the scheme are lower.
