Security Analysis of Efficient Anonymous Authentication With Conditional Privacy Preserving Scheme for Vehicular Ad Hoc Networks

Rui Qiao, Qinglong Wang, Zongtao Duan, and Na Fan

Abstract

Protecting a driver’s privacy is one of the major concerns in vehicular ad hoc networks (VANETs). Currently, Azees et al. has proposed an efficient anonymous authentication protocol (EAAP) for VANETs. The authors claim that their scheme can implement conditional privacy, and that it can provide resistance against impersonation attack and bogus message attack from an external attacker. In this paper, we show that their scheme fails to resist these two types of attack as well as forgery attack. By these attacks, an attacker can broadcast any messages successfully. Further, the attacker cannot be traced by a trusted authority, which means their scheme does not satisfy the requirement of conditional privacy. The results of this article clearly show that the scheme of Azees et al. is insecure.
