“…The system-master-key is added to the pseudonym generation formula to enhance the difficulty of the attacker's forgery signature, making the s cannot be bypassed. It can be seen that in the Du et al'scheme [25], part private key SK i was calculated by the system-master-key. The malicious signer cannot calculate the value of the system-master-key and SK i through technical means, but the public key of the certificateless signature scheme is not authenticated between the signer and the verifier, the malicious signer forges the signature by forging the secret value and bypassing the unknown system-master-key.…”

“…At present, many scholars have studied signcryption technology [21][22][23][24], but no systematic scheme formed. Du et al [25] put forward a certificateless signature scheme based on elliptic curve cryptosystemc but exist a replacement key attack. We improve Du et al's scheme, propose a certificateless signcryption scheme based on an elliptic curve, and the scheme is applied to the privacy protection of the IoV.…”

The application of digital signature technology on the Internet of Vehicles (IoV) is affected by its network and communication environment, which requires low transmission delay, power consumption, and highsecurity requirement. To the best of our knowledge, a well-designed solution that uses signcryption technology has not been proposed in the IoV research area. Motivated by the fact, a certificateless signcryption scheme based on Elliptic Curve Digital Signature Algorithm, which also considers pseudonym and timestamp mechanism, has been designed in this paper. We prove that our proposed scheme can be reduced to solving the difficulty of the Computational Diffie-Hellman problem under the standard model, show that the scheme meets both security and efficiency requirements, and provides a comparative analysis with the state-of-the-art schemes in terms of security analysis, computational cost, and communication cost, demonstrating that our proposed scheme is suitable to be deployed in the IoV environment.

“…According to the methodology given in [49], [50], we compute the average execution time (in ms) of these operations, summarized in Table 1. In Table 2, we compare the signing and verifying cost of our proposed IBS-secPKG scheme with related schemes such as Karati et al [29], Chen et al [32], Chen et al [33], Sahana et al [36], Shim et al [39], Tseng et al [38], Yang et al [40], Hussain et al [42] and Du et al [43] schemes. For signing a message, the proposed scheme takes 3𝑇 𝑆𝑀 + 1𝑇 𝐴 = 20.04 ms, whiles Karati et al [29], Chen et al [32], Chen et al [33], Sahana et al [36], Shim et al [39], Tseng et al [38], Yang et al [40], Hussain et al [42] and Du et al [43] schemes take 18.17 ms, 33.4 ms, 26.7 ms, 13.4 ms, 31.6 ms, 47.15 ms, 23 ms, 7 ms and 7 ms respectively.…”

Smart city is a concept of digitalizing the ecosystem to solve many urban area issues such as crime reduction, transportation, waste management, and governance. However, the security and threat-related issues are still neglected. This paper presents a secure smart city framework using an identity-based signature (IBS) scheme. It is challenging to employ IBS for a smart city (a large network size) due to its key escrow nature. So, we first proposed an identity-based signature scheme that mitigates the trust on a single private key generator (PKG) by employing multiple authorities to preserve the privacy of user’s private key via threshold cryptography. The system also offloads the key protection overhead to the multiple edge gateway, making the system as efficient as the generic IBS. We demonstrate the proposed scheme is secured against the following required attacks: forgeable attack, user slander attacks, and key abusing attacks assuming the computational Diffie-Hellman problem (CDHP) in the random oracle model (ROM). Additionally, the proposed system allows the recipient to verify multiple message-signature pairs at the least cost. The performance analysis determines the optimal signature size and least computational cost compared to related systems making the proposed system suitable for implementing a secure smart city.

Vehicular ad hoc networks (VANETs) create an vital platform for communication between vehicles, which can realize accident warning, auxiliary driving, road traffic information query, passenger communication and other applications. While providing convenient services for people, VANETs also bring some security risks. Security and privacy are the primary issues in the research of VANETs. Signcryption is an ideal way to transfer messages in a logical step in a secure and authenticated way. We design a Certificateless signcryption (CLSC) scheme to provide confidentiality, authentication, integrity, non‐repudiation and user privacy preservation for the information transmitted between vehicle communication units. We demonstrate the confidentiality and unforgeability of the proposed scheme in the random oracle model. Moreover, compared with the existing CLSC schemes, ours realizes the perfect combination of efficiency, security and privacy, and it is particularly well adapted to the secure communication of vehicle networks.
