Abstract
A method for securing an electronic control unit (ECU). The method may include generating a granular security control adjustment authorization ticket (G-SCAAT) for securing the ECU according to a plurality of security parameters determined based on to a role selected for a corresponding user. The G-SCAAT may include security values to be used in controlling the ECU to operate according to the security parameters.
Claims20
A method for securing an electronic control unit (ECU) comprising:
- receiving a request associated with a user requesting to program the ECU;
- selecting a role for the user from a plurality of available roles;
- and
- generating a granular security control adjustment authorization ticket (G-SCAAT) for securing the ECU according to a plurality of security parameters determined based on to the role selected for the user, including specifying security values within the G-SCAAT to be used in controlling the ECU to operate according to the security parameters.
A method for securing an electronic control unit (ECU) comprising:
- selecting a profile for securing the ECU from a plurality of available profiles, each of the profiles defining a plurality of security parameters for correspondingly securing the ECU;
- and
- generating a granular security control adjustment authorization ticket (G-SCAAT) for installation on the ECU, including specifying security values within the G-SCAAT for each of the security parameters defined for the profile selected, the ECU configured to secure the ECU according to the security values specified in the G-SCAAT.
A method for securing an electronic control unit (ECU) comprising:
- generating a granular security control adjustment authorization ticket (G-SCAAT) for installation on the ECU, the G-SCAAT specifying one or more security values for each of a plurality of security parameters;
- transmitting the G-SCAAT from a back office to the ECU as part of an installation process, the ECU configured to secure the ECU according to the security values specified in the G-SCAAT;
- and
- transmitting a log message from the ECU to the back office in response to the ECU performing an authentication process for authenticating the security values following installation of the G-SCAAT, the log message identifying one of a pass determination and a fail determination for the authentication process.
