Abstract: A vehicle obtains from a certification authority a certification that an authentic device is associated with a cryptographic key. The certification certifies that the cryptographic key is bound to information identifying the authentic device. The vehicle utilizes the cryptographic key obtained from the certification authority in cryptographic communication with the remote access device, and determines whether the remote access device is the authentic device based on whether the cryptographic key is successfully utilized in the cryptographic communication. Upon determining the remote access device is the authentic device, the vehicle may communicate further with the remote access device.

Abstract: A vehicle active network (12) communicatively couples devices (14–20) within a vehicle (10). Device operation is independent of the interface (22–28) of the device (14–20) with the active network (12). Additionally, the architecture of the active network (12) provides one or more levels of communication redundancy. The architecture provides for the total integration of vehicle systems and functions, and permits plug-and-play device integration and upgradeability.
