“…1 + 2. for the improved MLGS. Since the cost of pairing evaluation is more expensive compared to scalar multiplication [30], we see that the computational cost for our work is better than GSIS and more costly efficient compared to TAA as our work has the least pairing operation compared to others. Our work requires two pairings, while GSIS and TAA require three and five pairings respectively.…”

Vehicular ad hoc networks (VANETs) enable wireless communication between vehicles and roadside infrastructure to provide a safer and more efficient driving environment. However, due to VANETs wireless nature, vehicles are exposed to several security attacks when they join the network. In order to protect VANETs against misbehaviours, one of the vital security requirements is to revoke the misbehaved vehicles from the network. Some existing revocation protocols have been proposed to enhance security in VANETs. However, most of the protocols do not efficiently address revocation issues associated with group signature-based schemes. In this paper, we address the problem by constructing a revocation protocol particularly for group signatures in VANETs. We show that this protocol can be securely and efficiently solve the issue of revocation in group signature schemes. The theoretical analysis and simulation results demonstrate our work is secure against adversaries and achieves performance efficiency and scalability.

“…In order to assure secure communication in VANETs, different approaches [33] have been discussed in the literature. In this context, Gayathri et al [34] presents a pairing-free, certificateless authentication scheme that uses batch verification, while [35] introduces an identity-based fault-tolerant batch verification. In [36] the solution is based on a password-based conditional privacy preserving authentication and group-key generation protocol.…”

Air quality in urban environments has become a central issue of our present society as it affects the health and lives of the population all over the world. The first step in mitigating negative effects is proper measurement of the pollution level. This work presents a portable air pollution measurement system, built from off-the-shelf devices, that is designed to assure user privacy and data authenticity. Data is collected from sensor modules that can be hand carried or installed on vehicles, possibly leading to a vehicular sensor network that may cover a larger area. The main challenge is to provide authenticity for the sensor data while also ensuring user privacy. The proposed system assures authenticity and non-repudiation for the collected data by using group signatures and a blockchain-like structure for secure storage. We use regular key-exchange protocols based on elliptic curve cryptography in order to securely bootstrap a session key, then we benefit from secure tunneling to export data from sensors to the remote server. Post-update tampering is prevented by the use of a blockchain-like structure on the data server. We carry experiments both to determine the computational requirements of the procedures, as well as to measure indicators of air quality on nearby areas.

“…Compared with the above operations, the calculation cost of T h , T pa and T RSAv can be omitted according to [31], [32], and according to [38], the computational overhead of RSA encryption is the same as that of RSA verification. In addition, by summarizing the experimental results and conclusions from [33]- [35], we can obtain the following relationships of the execution time(ms) of the operations, as in (2)- (6).…”

A Privacy-Preserving Authentication and Pseudonym Revocation Scheme for VANETs

With the development of Intelligent Transportation Systems (ITS), Vehicular Ad hoc Networks (VANETs) have become a research hotspot in recent years. However, the vehicle communication system is vulnerable, resulting in threats to the privacy of users. This paper proposes a secure and efficient identity-based anonymous authentication scheme and uses pseudonyms to enhance the privacy protection of vehicle users. By improving the existing vehicle public key infrastructure and introducing Bloom filter to compress the Certificate Revocation List (CRL), the efficient pseudonym revocation scheme is then presented under the premise of ensuring user privacy. This scheme is able to perform batch pseudonym revocation and keep the pseudonym unlinkable. The security analysis shows that the proposed scheme is able to meet the security and privacy requirements in VANETs and CRL distribution.
