Abstract
A device for secure transmission of vehicle data over vehicle datalinks that may be shared with passenger devices and are connected to a publicly shared network is provided. The device comprises a processor embedded within a portion of an Ethernet cable for a vehicle. A plurality of applications resides in the processor and comprises a VPN application, and a VPN address and certificate update application. A first Ethernet transceiver communicates with the processor through the VPN application and also communicates with onboard electronic equipment. A second Ethernet transceiver communicates with the processor through the VPN application and also communicates with an external datalink. The VPN application automatically establishes a VPN when the datalink is available, provides an authentication certificate to verify that the device is a correct and legitimate node, and verifies a VPN hosting certification to determine whether the device is communicating with a correct and legitimate external facility.
