摘要：
Aiming at the problem that vehicle data is easy to be tampered and attacked in vehicle Ad Hoc networks(VANETs), a blockchain based VANETs group signature scheme is proposed. A blockchain-based car networking model is built to record data and prevent data from being tampered with. RSU acts as a miner and auxiliary supervisor to assist the supervision organization. Revocable group signature is adopted to ensure the confidentiality, confidentiality and non repudiation of information. The verification has nothing to do with the number of revocation members. Revocation only needs to update the revocation list. Some parameters can be calculated in advance to reduce the computational overhead. Finally, the correctness and security of the scheme are analyzed, and its performance is evaluated. © 2022, Jilin University Press. All right reserved.
