The Internet of Vehicles (IoV) counts for much in advancing intelligent transportation by connecting people, vehicles, infrastructures, and cloud servers (CS). However, the open-access wireless channels within IoV are susceptible to malicious attacks. Therefore, an authentication key agreement protocol becomes essential ensure secure vehicular communications protect vehicle privacy. Nevertheless, although vehicles group compromised, they can still update obtain communication content existing protocols. it is challenging guarantee post-compromise forward security (PCFS). Dynamic rotation a common approach realizing PCFS, which brings heavy computation burden. To address these issues, efficient robust continuous (ER-CGKA) scheme with PCFS designed IoV. propose-and-commit flow employed support asynchronous updates. Besides, cost overhead significantly reduced based on TreeKEM architecture. Furthermore, we adopt threshold mechanism resist collusion attacks enhances ER-CGKA scheme's robustness. Security analysis indicates that proposed satisfies all fundamental requirements achieves PCFS. performance evaluation results show our demonstrates reduction 18.82% (Client) 33.18% (CS) approximately, increase around 55.57% since pseudonyms utilized achieve conditional privacy-preserving. practical.
