title = "A simple authentication scheme and access control protocol for VANETs",
abstract = "In 2011, Yeh et al. proposed a PAACP: A portable privacy-preserving authentication and access control protocol in vehicular ad hoc networks. However, PAACP in the authorization phase is breakable and cannot maintain privacy in VANETs. In this paper, we present a cryptanalysis of an attachable blind signature and demonstrate that the PAACP{\textquoteright}s Authorized Credential (AC) is not secure and private even if the AC is secretly stored in a tamper-proof device. An eavesdropper can construct an AC from an intercepted blind document. Any eavesdropper can determine who has which access privileges to access which service. For this reason, this paper copes with these challenges and proposes an efficient scheme. We conclude that a simple authentication scheme and access control protocol for VANETs not only resolves the problems that have appeared, but also is more secure and efficient.",
