Vehicular technology has been violently developing recently, and triggers wide discussion. The Internet of Vehicles (IoV), as an important application of vehicular technology, is an emerging research intention. While the decentralization and high efficiency are in line with the needs of IoV, the dependable information transmission asks for a new kind of cryptography urgently. Despite the fact that a slew of related researches are designed, schemes may be vulnerable to privacy leakage, identity tracing, high computation overheads and so on. Therefore, it is urgent to propose a more secure and efficient scheme against various attacks. In this paper, an efficient authenticated key agreement scheme, titled as STCLA, is designed for fog-based IoV, adopting certificateless cryptography. Specifically, STCLA is based on efficient elliptic curve cryptographic technology and adopts pseudonym identity for user anonymity. Then, it is proved secure under random oracle model and is confirmed using Scyther tool. Further, the performance assessment is incorporated at last. Compared with several related schemes, STCLA can satisfy both security and efficiency at the same time.
