Abstract
Real-time Traffic information sharing can make the transportation more effective, which requires the vehicles on the road to participate in the road condition report actively. However, in the untrustworthy network environment, malicious traffic information dissemination will result in severe traffic issues, meanwhile, the risk of disclosure of users’ privacy information may also be increased. To address these problems, we propose a trust-based and secure real-time traffic information sharing scheme. Particularly, the trust value of the vehicle is calculated by the trusted organization, and the system updates the real road conditions according to the calculated results. Moreover, we utilize the improved pairing-free certificateless aggregate signature technique to provide the security service. As shown in the simulation results, the computing cost can be reduced because of using aggregate signature technique. In addition, the reliability of data is improved through trust management of vehicle users, and the sybil attack can be alleviated.
