The Internet of Vehicles (IoV) generates massive real-time data involving both user privacy and driving safety. To overcome the single-point-of-failure and key abuse risks of centralized cloud storage, we propose a secure and verifiable data sharing scheme based on cloud–edge collaboration. The scheme leverages edge–cloud cooperation to improve data access efficiency, employs ciphertext-policy attribute-based encryption (CP-ABE) for fine-grained access control, and adopts a multi-authority architecture with a permissioned PBFT-based blockchain deployed on resource-rich regional servers to ensure consistent key distribution without burdening resource-constrained edge nodes. In addition, BLS short signatures are integrated to verify data integrity. Performance evaluation of the blockchain prototype demonstrates acceptable transaction latency and manageable communication overhead, confirming the practicality of key consensus in real-world IoV deployments.
