| Summary: | Vehicular cloud network (VCN) is deemed as the most promising platform for providing transportation safety, road optimization, and valued-added application services. Because VCN is of distinguishing feature with super-large scale and unstable communication, it is a challenging task to study efficient authentication scheme for VCN without losing security and conditional privacy-preserving. To meet the challenge, a new efficient message authentication scheme is proposed in this paper. A batch message verification and signature aggregation are included in the proposed scheme to improve the authentication efficiency and decrease the communication cost. Compared with the similar conditional privacy-preserving authentication schemes, the proposed scheme has superior performance in computation and communication cost. Simulation analysis further proves that the proposed scheme has better advantages in reducing the verification loss rate and message delay in the application of VCN. |
