Anonymous Authentication Scheme Based on One-off Public Key in VANET

摘要

The available anonymous authentication schemes in VANET have some drawbacks in security and efficiency. Then, a new anonymous authentication scheme based on one-off public key is proposed. It constructs the signature of timestamp using the one-off public key as authentication proof to realize anonymous authentication, establishes secure session key and provides the method of revealing malice nodes. It is shown that the proposed scheme has superiority in both security and efficiency, and is more suitable for wireless networks.
