ECMV: Efficient Certificate Management Scheme for Vehicular Networks

In this paper, we propose an Efficient Certificate Management scheme for Vehicular networks (ECMV). The proposed scheme offers a flexible interoperability for certificate management in different administrative authorities, and an efficient way for any On-Board Units (OBUs) to update its certificate anywhere at anytime. In addition, an efficient time-limited certificate revocation for OBUs is introduced. It is demonstrated that the ECMV scheme can decrease the complexity of certificate management, and achieves excellent security and efficiency for vehicular communications.
