PACP: An Efficient Pseudonymous Authentication-Based Conditional Privacy Protocol for VANETs

摘要: In this paper, we propose a new privacy preservation scheme, named pseudonymous authentication-based conditional (PACP), which allows vehicles in vehicular ad hoc network (VANET) to use pseudonyms instead of their true identity obtain provably good privacy. our interact with roadside units help them generate for anonymous communication. setup, the are only known but have no other entities network. addition, scheme provides an efficient revocation mechanism that be identified and revoked from if needed. Thus, provide system, is, will until they revoked, at point, cease anonymous.
