PPREM: Privacy Preserving REvocation Mechanism for Vehicular Ad Hoc Networks
We design a mechanism to convey revocation data that preserves the users privacy. Certificate status checking can be performed within few milliseconds. Fresh revocation data is available even when disconnected from the infrastructure. Even if RSUs are compromised, attackers cannot infer personal information. Even if RSUs are compromised, attackers cannot infer personal information. Message loss ratio due to authentication delay is reduced to less than 5%.
