Vspp: Verifiable, shareable, and privacy-preserving access control scheme for IoV

Abstract

Internet of Vehicles (IoV) is a specialized application of Internet of Things (IoT), which interconnects vehicles and cloud platforms by using various communication devices and computing technologies to realize the transmission and sharing of vehicle information and enhance the driving experience. However, vehicle users face challenges in identity, data, and inside security when using IoV. In order to solve these problems, we propose a verifiable, shareable, and privacy-preserving access control scheme for IoV. In our scheme, we use zero-knowledge proof (ZKP) to ensure the security of user identity. More specifically, it can enable user anonymity and authenticity without revealing any additional information associated with the user. Meanwhile, we employ proxy re-encryption (PRE) to provide confidential sharing and secure the operation of data. In addition, we use the cryptographic reverse firewall (CRF) to ensure users’ internal security. It can prevent algorithm substitution attacks while ensuring chosen plaintext attack security. Finally, compared to other schemes, our scheme not only enables anonymity, traceability, unlinkability, and confidentiality but is also resistant to insider attacks. Performance evaluation shows that our scheme surpasses the other schemes in terms of time and storage costs.
