AB - Vehicular ad hoc networks (VANETs) refer to ad hoc networks where many vehicles and other devices connect to wireless communications and exchange their information. The combination of VANETs in a heterogeneous Internet of Things (IoT) allows vehicles belonging to different cryptosystems to communicate with each other. An essential purpose of the VANET is to implement Vehicle-to-Roadside units (V2R) and Vehicle-to-Vehicle (V2V) communications over a reliable telecommunication channel. Therefore, authentication and privacy are the prime goals of a secure connection. This paper proposes a practical heterogeneous signcryption system for vehicular communication (PHSC-VC) with a pairing free to make V2V communication in VANETs more secure. In PHSC-VC, a vehicle registered in a Certificateless Cryptosystem (CLC) environment can exchange its information with another vehicle registered in a Public-Key Infrastructure (PKI) environment. The recommended protocol meets VANET security requirements such as authentication, unforgeability, confidentiality, and integrity simultaneously at a lower cost. Also, it is effective in high-traffic areas. Besides, under the Computational Diffie-Hellman (CDH) and Discrete logarithm (DL) concerns, the random oracle model reveals that PHSC-VC scheme is secure. Finally, as shown in the performance analysis, our protocol shows lower computation cost, better communication efficiency, and lower power consumption. Hence, PHSC-VC is practical and efficient in achieving cryptography in limited devices such as VANETs.
