Anonymous authentication is a critical step in safeguarding vehicle privacy and security in VANETs. VANETs connected with blockchain are gaining popularity as a means to increase the effectiveness of anonymous authentication across many security domains. However, present blockchain-assisted authentication systems cannot successfully achieve anonymity since colluding RSUs or vehicles may acquire linkability via the same retrieved record, hence destroying anonymity. To solve the problem, the proposed work offers an unlinkable anonymous signature-based authentication for VANET to ensure collusion resistance. To provide V2R unlinkability, a trusted authority issues anonymous parameters that conceal the vehicle's identification from RSUs and other vehicles in the VANET system. The vehicle user produces anonymous signatures, and RSUs validate them during anonymous authentication. Moreover, the proposed authentication methods are based on an anonymous certificateless signature (ACS) approach that is computationally more efficient and provably safe against eternal forgery in the random oracle model. Additionally, the proposed work guarantees that neither an RSU nor a vehicle has the authority to divulge users’ true identities. Hence, the proposed system has stringent unlinkability and better anonymity, and it enhances the efficiency of V2R and V2V communications considerably according to security analysis and performance assessment.

“…According to Table 2, the security analysis is evaluated to gain a full understanding of the security properties that are negligible in each scheme. It is found that the schemes [6], [7] achieve non-repudiation based on exchanging certificates between the entities within the network. As a result of this, a high communication burden is introduced, leading to a waste in the network bandwidth.…”

“…Although the scheme does not require a fully trusted TA to generate the vehicle secrets, exchanging certificates is still a communication drawback in this scheme. Additionally, an identity-based authentication scheme that utilizes pseudonyms to ensure the privacy of the vehicle's driver is presented in [7]. This scheme achieves non-repudiation feature, however, it is mainly focused on the certificate revocation list (CRL) that hinders the communication process.…”

It is crucial to support emergency applications provided by vehicular adhoc network (VANET) through enabling vehicles to quickly access to the infrastructure and consequently request rescue services. Additionally, the communication channels between vehicles and the infrastructure lack various security features due to the inferior wireless characteristics of their environment. However, most of the existing authentication schemes which are used to fix the security drawbacks lead to heavy computations and large storage burdens on the vehicle onboard unit (OBU). These schemes utilize secure channels while distributing the network parameters between the various participants. Yet, it is not efficient to establish secure channels during the interactions between entities. Furthermore, lightweight cryptography is an efficient security solution which is adequate for OBU to maintain a reasonable efficiency with low computational and communication costs. Two basic demerits for lightweight authentication protocols are highlighted as follows: Firstly, symmetric key-based authentication protocols dismiss achieving non-repudiation feature, leading to several security attacks in VANET. Secondly, public key-based authentication schemes are relied on elliptic curve cryptography (ECC) which makes the protocol implementation more difficult. Hence, this paper introduces a novel authentication protocol that utilizes Chebyshev chaotic maps to secure connectivity between the vehicles and infrastructure without using secure channels to distribute the network parameters. The new protocol combines the concept of the symmetric key cryptography with the public key signature to satisfy both the lightweight property and non-repudiation feature. Thus, this protocol introduces a novel network model which is the lowest hardware complexity, compared with others. The performance analysis is performed by Wolfram Mathematica, proving that the proposed protocol is superior in terms of security and performance aspects; its computation and storage costs of OBU are enhanced with 24.09% and 16.99%, respectively, compared to the most competing scheme. Besides, the Scyther simulation confirms the security of the protocol.

“…Moreover, several features, like the proximity of emergency centers, hospitals, police stations, driving weather conditions, and so on, are to be shared with the nearby vehicles for efficient communication. With the introduction of the VANET system, the sharing of critical information has been made possible [1]. VANETs are distributed, self-organizing communication networks comprised of moving vehicles.…”

Recent development in intelligent transport systems (ITS) has led to the improvement of driving experience in vehicular ad-hoc network (VANET) systems. Providing a low computational cost with high serving capability, however, is a critical phenomenon in the current VANET system. In the existing scenario, when the authenticated vehicle user moves from one roadside unit (RSU) to another RSU region, re-authentication of the vehicle user is required by the current RSU, which increases the computational complexity. To overcome the above-mentioned challenge, a blockchain-based authentication protocol is developed in this work. In this suggested process, blockchain is integrated with VANET, which enables the authentication of the vehicle user without the involvement of a trusted authority. Moreover, the integrity of the message and privacy of vehicle users are preserved in the blockchain network. Even though many blockchain-based schemes have been proposed recently, the existing schemes were not focused on conditional anonymity. However, in our proposed scheme, conditional privacy is introduced to revoke the malicious vehicles in the case of disputes and to avoid further damage to the VANET system. As a result, the proposed scheme provides an efficient mechanism for anonymous authentication, privacy, and integrity preservation with conditional tracking. Finally, the defense against different security threats is explained in the security analysis section, and the performance investigation section shows the competence and efficacy of our method with similar related methods.
