“…However, the proposed scheme is found to be vulnerable to Denial of Service (DoS) attacks when false data is injected. Similarly, Jiang et al [140] propose an Anonymous Authentication scheme based on group signature (AAAS). AAAS allows a good level of performance since it adopts a pseudonym mechanism and identity based group signature to eliminate the overhead generated by the management of public key certificates.…”

With the proliferation of embedded technologies and wireless capabilities, today's vehicles are no longer isolated mechanical machines. They become part of a hyper-connected system-Intelligent Transportation Systems (ITS)-that has the potential to support multiple levels of autonomy and intelligence improving considerably the safety, efficiency, and sustainability of transportation networks. However, this raises new security issues that make the whole system prone to cybersecurity attacks that threaten both the safety and privacy of all road-users. This paper gives a short background tutorial on the main security issues and the different attacks that hinder Intelligent Transport Systems. To enable secure and safe ITS applications, this paper provides a comprehensive analysis of existing solutions and highlights their strengths and limitations. Finally, this survey presents key challenges in the field, and discusses recent trends that must be factored in by researchers, implementers, and car manufactures to improve the security of ITS.

Vehicular ad-hoc network (VANET) has been gaining importance due to the fast growing technology as well as its requirements in intelligent transportation systems (ITS) and vehicular social network (VSN). VANET facilitates vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communication and improves the ride quality with value added services. The number of connected vehicles is expected to grow to a huge number with enormous exchange of safety and non-safety messages which are susceptible to security and privacy threat. To ensure secured communication, VANET must implement an authentication protocol to resist the attack and preserve the privacy. In this paper, a detailed discussion on the taxonomy for authentication schemes in VANET has been presented. The authentication schemes have been compared with security, privacy and scalability requirement. The use of recent technologies such as 5G, 5G-SDN, and Blockchain to design authentication schemes with low cost, and low communication, computational overhead has been discussed. Finally, the paper concludes with open challenges in VANET authentication. This paper is expected to open new avenues for researchers working in the domain of VANETs.

Vehicular ad-hoc networks (VANETs) play an essential role in the development of the intelligent transportation system (ITS). VANET supports many types of applications that have strict time constraints. The communication and computational overheads are minimal for these computations and there are many security requirements that should be maintained. We propose an efficient message authentication system with a privacy preservation protocol. This protocol reduces the overall communication and computational overheads. The proposed protocol consists of three main phases: the group registration phase, send/receive messages phase, and the leave/join phase. For cryptography algorithms, we combined symmetric and asymmetric key algorithms. The symmetric key was generated and exchanged without using the Diffie–Hellman (DH) protocol. Furthermore, we used an efficient version of the RSA algorithm called CRT-RSA. The experimental results showed that the computational overhead in the registration phase was significantly reduced by 91.7%. The computational overhead for sending and receiving the non-safety message phase was reduced by 41.2% compared to other existed protocols. Moreover, our results showed that the time required to broadcast a safety and non-safety group message was below 100 ms and 150 ms, respectively. The average computational time of sending and receiving a one-to-one message was also calculated. The proposed protocol was also evaluated with respect to performance and security and was shown to be invulnerable to many security attacks.
