Cloud-assisted intelligent transportation systems depend on cloud computing to provide powerful computing capabilities and big data storage services. As precise intelligent traffic control and dispatch policies are heavily based on real-time traffic information (e.g., unmanned driving test information), any altered data may cause severe consequences. The integrity of outsourced critical traffic control data has been the most concerning security issue. To this end, a lightweight proxy-oriented data integrity checking mechanism has been devised, without incurring substantial certificates management. The mechanism enables a data manager in traffic information control center to delegate the proxy to produce the signatures of encrypted data and outsource them to the cloud server, dramatically alleviating the work intensity of the data manager. By integrating blockchain into the mechanism, it gives assistance to the data manager for validating malicious integrity checking behaviors. The comprehensive security analysis and performance evaluation demonstrate the feasibility of the mechanism in the deployment of cloud-assisted intelligent transportation systems.
