Abstract
Secure subscription based vehicle data services are provided. In one embodiment, a device comprises: a non-volatile memory comprising an embedded public key (EPK) that comprises a public key of a public-private key pair associated with a data service system not onboard the vehicle; a protocol that initiates a communication session that includes a session validation sequence that causes a processor to transmit a session request message and validate an authenticity of a session reply request using the EPK; the protocol includes a session initiation sequence that causes the processor to: transmit an initiation request message to the data service system that includes a key derivation key, and apply the key derivation key to a key derivation function to generate a message authentication key. The processor authenticates uplink messages exchanged with a host data service using the message authentication key.
