“…To improve the efficiency, Han [7] proposed a certificateless aggregated signature without bilinear pairing, which aggregates individual signatures in messages transmitted by different vehicles into a short signature, and signature checking can meet the security requirements. Samra [29] introduced a certificateless aggregation scheme for traceable ring signatures, aimed at reducing computational overhead. This approach notably diminishes the computational burden associated with signature verification, while simultaneously ensuring conditional privacy protection.…”

Vehicle-Infrastructure Cooperative Systems (VICS) are widely used in the safe driving and management of operating vehicles (OV). To preserve privacy and resist harmful attacks, digital certificates and signatures are used during vehicle communication. Nonetheless, the existing secure protocol cannot enable the road control center (RCC) to track the anonymous OV in real-time. To implement this additional functionality, this paper proposes a real-time tracking protocol for anonymous OV based on pseudonym certificates and Optimal Asymmetric Encryption padding (OAEP). In this protocol, pseudonym certificates ensure the security of the OV; the OV's real identity padding by OAEP is encrypted as a ciphertext, which is transmitted to RCC in communication, and RCC decrypts it to achieve real-time tracking. According to the security reduction proofs under the Elliptic Curve Discrete Logarithm Problem (ECDLP) given in the random oracle model (RO), the protocol can satisfy the security requirements. Additionally, the performance analysis based on MIRACL shows the protocol is slightly weaker than others, and we analyze the cost of real-time tracking for the reason. Finally, the RSU service rate of the protocol is analyzed according to the performance and velocity-density model, which proves the protocol is stable in this system.INDEX TERMS Vehicle-infrastructure cooperative systems, anonymous authentication, conditional privacy, elliptic curve, real-time tracking.

“…Te scheme emphasizes the security of exculpability of the vehicle. Subsequently, Samra and Fouzi [11] further compressed the computation and communication overhead based on ring signatures. Batch verifcation technology is used to improve the efciency of message verifcation in many schemes [5,10,11].…”

Message authentication and conditional privacy preservation are two critical security issues in VANETs (vehicular ad hoc networks). To achieve the corresponding security goals, many security technologies have been proposed so far. Identity-based pseudonyms and group signature-based schemes are two of the main technologies in recently published literature. However, the key escrow is difficult to achieve and pseudonym identities may reveal the physical location of the vehicle in the identity-based scheme. The global manager TA of VANETs knows the full keys given to the vehicles and can forge signatures under the vehicle’s key. Therefore, the exculpability cannot be satisfied in the group signature scheme. To address these security issues, a privacy-preserving authentication scheme for VANETs with exculpability is proposed in this paper, which applies double key approach to realize the trusted communication between vehicle and road side units and TA by combining the advantage of group-based methods and identity-based methods. Security analysis shows that the security of our scheme can resist stronger attacks than previous schemes.

“…In addressing the difficulty of sharing medical records between healthcare organizations, Lai et al [ 25 ] introduced a secure medical-data-sharing scheme based on traceable ring signatures and blockchain. Samra et al [ 26 ] proposed a new framework, a certificate-less aggregation scheme based on traceable ring signatures (CLA-TRS), which ensures conditional privacy-preserving authentication in vehicular ad-hoc network (VANET) communications. Table 1 summarizes the application scenarios, techniques, advantages, etc., of the above schemes.…”

Blockchain integrates peer-to-peer networks, distributed consensus, smart contracts, cryptography, etc. It has the unique advantages of weak centralization, anti-tampering, traceability, openness, transparency, etc., and is widely used in various fields, e.g., finance and healthcare. However, due to its open and transparent nature, attackers can analyze the ledger information through clustering techniques to correlate the identities between anonymous and real users in the blockchain system, posing a serious risk of privacy leakage. The ring signature is one of the digital signatures that achieves the unconditional anonymity of the signer. Therefore, by leveraging Distributed Key Generation (DKG) and Elliptic Curve Cryptography (ECC), a blockchain-enabled secure ring signature scheme is proposed. Under the same security parameters, the signature constructed on ECC has higher security in comparison to the schemes using bilinear pairing. In addition, the system master key is generated by using the distributed key agreement, which avoids the traditional method of relying on a trusted third authorizer (TA) to distribute the key and prevents the key leakage when the TA is not authentic or suffers from malicious attacks. Moreover, the performance analysis showed the feasibility of the proposed scheme while the security was ensured.
