“…Then, the problems of decision delay are discussed in the next subsection. Meanwhile, the adaptive decision‐making method is also introduced . The adapted model location privacy metric is discussed in this section and also how to obtain maximum service usability constraints by location privacy.…”

“…First problem is that long time period during this interval may cause vehicles to receive malicious event messages. Another problem is time efficiency in decision making because pseudonym time will expire, so malicious vehicle cheats other vehicles more easily to receive malicious event messages rather than RS event messages which will have an effect on decision and adversely know the vehicle's exact identity …”

Summary In intelligent transportation systems, the messages transmitted and received from one vehicle to another vehicle may enhance location privacy scheme; falsification message forwarding collusion attack, timing, and transition attacks all are serious issues and must be addressed in event trust management. Without which, decision making on event message may endanger the whole transportation system and may even threat the human life. In addition, pseudonym expiry is another critical issue of location privacy. The time interval of decision waiting even has been the critical accident response time. In this paper, we proposed a new novel mix zones and dynamic pseudonym trust management system, called MADPTM, which aims to prevent against attackers under privacy‐enhanced road networks. On shortening the pseudonym expiry, we propose dynamic pseudonym trust management system, with the assistance of reported server. We performed a set of simulations under many trust attack models to evaluate the performance and efficiency of the proposed system. Our proposed MADPTM method proved to be highly resilient to various attacks, and simulation results verified that our method outperforms other existing methods.

“…Among various security threats, privacy preservation in VANETs is one of the new challenges of protecting users' private information. For instance, Chen and Wei [2,10] proposed a safe, distance-based location privacy scheme called SafeAnon. By simulating vehicular mobility in a cropped Manhattan map, they evaluated the performance of the SafeAnon scheme under various conditions to show that it could simultaneously achieve location privacy as well as traffic safety.…”

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'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.

Privacy and security are very important in vehicular ad hoc networks (VANETs). VANETs are negatively affected by any malicious user's behaviors, such as bogus information and replay attacks on the disseminated messages. Among various security threats, privacy preservation is one of the new challenges of protecting users' private information. Existing authentication protocols to secure VANETs raise challenges, such as certificate distribution and reduction of the strong reliance on tamper-proof devices. 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'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 an improving authentication scheme and access control protocol for VANETs not only resolves the problems that have appeared, but also is more secure and efficient.
