SYSTEMS AND METHODS FOR ENCRYPTED VEHICLE DATA SERVICE EXCHANGES

The title of the invention is systems and methods for encrypted vehicle data service exchange. Encrypted vehicle data service exchanges are provided. In one embodiment, a vehicle communication manager comprises memory storing an embedded public key (EPK) for a data service; a processor executing a vehicle data service protocol to initiate a session with the data service. The protocol causes the processor to: transmit a session request to the data service and receive a session reply, wherein the reply indicates if the manager is authorized for encrypted service, the processor validates authenticity of the session reply using the EPK; determine whether to enable message encryption, and transmit an initialization request indicating whether encryption is elected; generate a key derivation key (KDK) and transmit the KDK to the data service; receive an initiation response confirming whether message encryption is elected; and when elected, generate at least one Message Encryption Key (MEK) from the KDK; encrypt data
