【Abstract】An essential goal of the Internet of Vehicles (IoV) is to allow vehicles' peer connections and contact a service provider through a secure communication channel. However, privacy and authentication are considered the main objectives of secure communication. In this paper, we propose an efficient Online/Offline signcryption of heterogeneous systems based on blockchain to secure data sharing between the IoV and internet servers. The blockchain prevents tampering with compatibility information. Further, the smart contract addresses the weakness of internet servers, such as passing incorrect data to the IoV nodes. The proposed protocol satisfies the security requirements of IoV, such as integrity, authentication, unforgeability, and confidentiality in a single logical step. We introduce the construction of our Efficient Heterogeneous Signcryption Scheme for Internet of Vehicles (EHSC-IoV) and verify that our protocol is secure under the Discrete Logarithm (DL) and the Computational Diffie-Hellman (CDH) assumptions. As compared with the existing five heterogeneous signcryption schemes, the performance evaluation and simulation results show that the computational cost of the IoV nodes in our protocol reduced by about 75%,84.2%,80%,67.9%, and 82.4%, respectively, and the total energy consumption of the IoV nodes in our protocol reduced by about 69.4%,75.4%,75.2%,62.3%, and 75.1%, respectively.
