Quantum Identity Authentication Scheme of Vehicular Ad-Hoc Networks

With the development of the intelligent transportation system (ITS) and increasing application of vehicular ad-hoc networks (VANETs), the security of VANETs has become a crucial issue for VANETs and ITS. In this study, we propose a quantum VANETs protection scheme to address the security issue of vehicular identity authentication. It based on BB84 quantum key distribution protocol and quantum mechanics. Furthermore, the novel quantum scheme can defend most VANETs-aimed attacks. It also can be applied on connection of vehicle to everything (V2X), this is because reliability and security problem can be solved in proposed quantum scheme. By tactfully exploiting properties of quantum mechanics, our proposed scheme offers remarkable advantages which include remote identity authentication, identity revocation and irreversibility. The security analysis shows that our proposed scheme can further insure the security of VANETs identity authentication.
