Abstract:

An apparatus and method of a hardware isolated secure element protecting a plurality of mission critical subsystems are provided. The method includes performing an actuation operation received across an unsecure path that modifies the state of a mission critical subsystem, performing a diagnostic operation received across the unsecure path that requests state information of the mission critical subsystem, storing information used to determine which of the diagnostic operation and the actuation operation received across the unsecure path are performed, and flashing an execution image of an electronic control unit when the execution image of the electronic control unit is received across the unsecure path.

Abstract:

An apparatus and method of an attachment device for interfacing with an on-board diagnostic system of a vehicle is provided. The device includes an application processor configured to receive input from a terminal, control processing of the input by the on-board diagnostic system, transmit a result of the processing of the input by the on-board diagnostic system to the terminal, and a secure element interposed in the communication path between the application processor and the on-board diagnostic system, the secure element configured to filter the input of an on-board diagnostic operation that is untrusted.
