Although many revocable group signature schemes has been proposed in vehicular ad hoc networks (VANETs), the existing schemes suffer from long computation delay on revocation that they cannot adapt to the dynamic VANETs. Based on Chinese remainder theorem and Schnorr signature algorithm, this paper proposes an efficient revocable group signature scheme in VANETs. In the proposed scheme, it only need to update the corresponding group public key when a member quits the group, and in the meanwhile the key pairs of unchanged group members are not influenced. Furthermore, this scheme can achieve privacy protection by making use of blind certificates. Before joining to the VANETs, users register at local trusted agencies (LTAs) with their ID cards to obtain blind certificates. The blind certificate will be submitted to roadside units (RSUs) to verify the legality of users. Thus, the real identities of users can be protected. In addition, if there is a dispute, users can combine to submit open applications to RSUs against a disputed member. And LTAs can determine the real identity of the disputed member. Moreover, since the key pairs employed by a user are different in different groups, attackers are not able to track the movement of users with the obtained public keys in a group. Furthermore, performance analysis shows that proposed scheme has less computation cost than existing schemes.

“…Most of privacypreserving authentication protocols have been developed on the basis of digital signature including group signature schemes and anonymous certificates using pseudonyms of vehicles to conceal the real identity of vehicles or users [5,12,13,16,18]. However, those protocols cannot fulfill the location assurance requirements in our mind.…”

A location-aware service on a vehicular ad hoc networks (VANETs) is to provide services that distribute on-demand information for a certain geographic area of interest by taking advantage of vehicular communications. In this paper, we propose a secure and location assurance protocol in order to guarantee privacy preservation in vehicular communications and trustworthiness of location-aware services over VANETs. The proposed protocol enables a message verifier to have confidence that the location-aware information was responded from the vehicles passing through the target location area of interest without violating location privacy of the responders. To achieve our security objectives, we consider a pseudonym-based privacy-preserving authentication and a hierarchical identity-based cryptographic scheme. Furthermore, we demonstrate experimental results to confirm the efficiency and effectiveness of the proposed protocol.

“…It is worth noting that massive vehicular data from all the legitimate VANET entities are aggregated and analyzed in TA side. Obviously, tremendous computation ability and storage are required [5], [6]. Nowadays, sophisticated communicating and processing techniques, including the promising 5G networks and cloud computing, have been dedicated to heterogeneous IoT environment including VANETs, where sufficient computing and storing resources can be guaranteed [7], [8].…”

Nowadays, with rapid advancements of vehicular telematics and communication techniques, proliferation of vehicular ad hoc networks (VANETs) have been witnessed, which facilitates the construction of promising intelligent transportation system (ITS). Due to inherent wireless communicating features in open environment, secure transmission among numerous VANET entities remains crucial issues. Currently, lots of research efforts have been made, while most of which tend to allocate the universal group key to the verified devices for both vehicle-to-vehicle (V2V) and vehicle-to-RSU (V2R) communications. However, in heterogeneous VANET environment with large numbers of devices in same vehicular group, complicated and variable topologies lead to continuous key updating in every moment, causing interference to regular V2R data exchange, which is not reliable and efficient for resource-constrained VANET environment. Moreover, group membership recording and detecting mechanisms are necessary for real time vehicle revocation and participation, which has not been further studied so far. In this paper, we address the above issues by proposing a secure authentication and key management scheme. In our design, novel VANET system model with edge computing infrastructure is adopted so as to offer adequate computing and storing capacity compared to traditional VANET structure. Note that our certificateless authentication scheme applies the independent session key for each vehicle for interference avoidance. Furthermore, consortium blockchain is employed for V2V group key construction. Real time group membership arrangement with efficient group key updating is accordingly provided. Formal security proofs are presented, demonstrating that the proposed scheme can achieve desired security properties. Performance analysis is conducted as well, proving that the proposed scheme is efficient compared with the state-of-the-arts.
