Abstract
A system and a method using that system is provided for establishing a secure communication channel between a vehicle and a mobile device. The method may include providing at least one unique mobile device identifier and at least one unique vehicle telematics unit identifier associated with the mobile device identifier to a call center. At least one of the two identifiers may be provided to a wireless service provider. Two private keys may be generated—a first private key based on the at least one unique mobile identifier and a second private key based on the at least one unique vehicle telematics unit identifier. The first private key may be provided to the mobile device within a first cryptographic envelope signed with a first cryptographic key. And the second private key may be provided to the vehicle telematics unit within a second cryptographic envelope signed with a second cryptographic key.
