Connected vehicular cloud computing applies cloud computing to Vehicular Ad Hoc Networks (VANETs); which can provide road condition monitoring services for intelligent transportation systems. However; it brings new security and efficiency challenges to VANETs. Specifically; malicious vehicles may impersonate legitimate vehicles to tamper with or forge road conditions. Cloud servers are not fully trusted entities; the vehicle information; driver information; as well as road conditions uploaded to the cloud may be leaked to an unauthorized party. Moreover; small devices such as on-board units and roadside units have limited computational resources; and thus require light-weight security mechanisms. To address these challenges; this article proposes a blockchain-assisted road condition monitoring scheme with privacy-preserving. It prevents the leakage of sensitive vehicle identity with pseudonyms; protects the privacy of road conditions through encryption; identifies malicious vehicle impersonation attacks with source authentication; and detects dishonest behaviors of cloud servers with blockchain supervision. Our scheme does not rely on expensive bilinear pairing operations; which significantly reduces the computational overheads. Security analysis shows that our proposal can provide unforgeability of authentication request/response; privacy of road conditions; resistance to reply attacks; anonymity of vehicle; and traceability of malicious vehicles. Performance analysis demonstrates that our work has lower computational and communication costs than other existing schemes. © 1967-2012 IEEE;
