摘要

This paper presents a secure group communication scheme to relieve the bottleneck problem of vehicular authentication efficiency using batch verification to accelerate the authentication speed during the group construction phase. We use a certificateless public key cryptosystem encryption scheme to overcome the key escrow problem. Specific to the revocation of malicious vehicles, a bloom filter is applied to issuing the information of the revoked vehicles instead of the time-consuming revocation list. By performance evaluation, the proposed scheme outperforms previously reported schemes in terms of the authentication delay and transmission overhead.
