Abstract
In a vehicle-to-vehicle communication network utilizing PKI security methods to protect communications and in which the PKI encryption utilizes a Certificate Authority having both a private key and a publicly distributed key, a method for allocating multiple certificates for each vehicle which are assigned to each vehicle in the communication network. The method includes the step of assigning a unique secret key k to each vehicle in the communication network. The Certificate Authority then creates a plurality of public key and private key encryption pairs for each vehicle and each encryption pair is associated with an index i. A plurality of certificates are then created with one certificate for each value of the index. A revocation list comprising the secret keys is maintained by the Certificate Authority so that all encryption pairs assigned to a particular vehicle may be revoked by the secret key k corresponding to that vehicle.
