Strong privacy preserving authentication scheme for unmanned cars

The vehicular ad hoc network (VANET) has several security issues. Identification requires accurate authentication, but privacy must be kept secretly. In this paper, we propose a strong privacy preserving authentication scheme to solve these problems based on vehicles to infrastructures (V2I) communication. We introduced public key infrastructure (PKI) and message accessing code (MAC) encryption. We define adversary model in two types external and internal. We demonstrate how our methods are safe for these attackers.
