摘要：The group signature based security scheme is a promising approach to provision privacy in vehicular ad hoc networks (VANETs). In this paper, we propose an distributed key management scheme instead of centralized key management for group signature based VANETs, which is expected to considerably facilitate the revocation of malicious vehicles, location privacy protection, heterogenous security policies, and maintenance of the system, compared with the centralized key management assumed by the existing group signature schemes. In the proposed scheme the road side units (RSUs) will be responsible for distributing group private keys in a localized manner
