Abstract
Internet of Vehicles (IoV) is a specialized breed of Vehicular Ad-hoc Networks (VANETs) in which each entity of the system can be connected to the internet. In the provision of potentially vital services, IoV transmits a large amount of confidential data through networks, posing various security and privacy concerns. Moreover, the possibility of cyber-attacks is comparatively higher when data transmission takes place more frequently through various nodes of IoV systems. It is a serious concern for vehicle users, which can sometimes lead to life-threatening situations. The primary security issue in the provision of secure communication services for vehicles is to ensure the credibility of the transmitted message on an open wireless channel. Then, receiver anonymity is another important issue, i.e., only the sender knows the identities of the receivers. To guarantee these security requirements, in this research work, we propose an anonymous certificateless signcryption scheme for IoV on the basis of the Hyperelliptic Curve (HEC). The proposed scheme guarantees formal security analysis under the Random Oracle Model (ROM) for confidentiality, unforgeability, and receiver anonymity. The findings show that the proposed scheme promises better security and reduces the costs of computation and communication.
Highlights
Over the past few decades, academic and industry researchers have worked harder to push the technology of Mobile Ad hoc Networks (MANETs) to a new extreme [1]
MANETs evolved over time too, and one of the most advanced forms, Vehicular Ad hoc Networks (VANETs), was introduced, in which peer vehicles exchange information [3]
The environments of Internet of Vehicles (IoV) could be dangerous in the absence of security protections
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. The Internet of Vehicles (IoV), a hybrid of VANETs and the Internet of Things, sometimes known as IoT on wheels, relies heavily on V2X communication. IoV is a dynamic mobile connectivity infrastructure that provides a low-cost networking solution for connecting vehicles to the public network in order to improve transportation system safety and performance [5]. Some of the well-known common security and privacy issues across the IoV environment include tracking vehicle locations, hardware tampering, unauthorized data access, message modification, and fabrication [8]. The elliptic curve cryptography is used to provide the security and efficiency with a key-size up to 160 bits. 80-bit key size, and, at the same time, promises the security features characteristic of elliptic curve, bilinear pairing, and RSA.
