Abstract
A wireless vehicle and infrastructure system is described that allows for utilization of a quasi-anonymous common private key/digital certificate pool, such that all vehicles are authenticated to the system, but no one vehicle/user can be readily identified during their use of the system because of their use of set of common private key/digital certificate pairs that are assigned to each vehicle from the pool and are common across multiple vehicles. Vehicle/user anonymity is only temporarily removed during vehicle/user re-authentication and re-issuance of new common private key/digital certificate pairs from the pool in the wireless vehicle and infrastructure system.
