Abstract
A method includes, in response to a request to enable a set of firmware features in a processing device, performing a validation process based on a key certificate associating a first entity identifier with a firmware feature description file indicating the set of firmware features, and in response to a violation detected during the validation process, enabling a countermeasure in the processing device.
Claims20
A method, comprising:
- in response to a request to enable a set of firmware features in a processing device, performing a validation process based on a key certificate associating a first entity identifier with a firmware feature description file indicating the set of firmware features, wherein the first entity identifier is associated with a user entity;
- and
- in response to a violation detected during the validation process, enabling a countermeasure in the processing device.
A computing device, comprising:
- authentication logic circuitry configured to, in response to a request to enable a set of firmware features in a processing device, perform a validation process based on a key certificate associating a first entity identifier with a firmware feature description file indicating the set of firmware features, wherein the first entity identifier is associated with a user entity;
- and
- countermeasure logic circuitry coupled with the authentication logic circuitry and configured to, in response to a violation detected during the validation process, enable a countermeasure in the processing device.
A computing system, comprising:
- a server device configured to generate a key certificate;
- and
- a processing device coupled with the server device, comprising:
- authentication logic circuitry configured to, in response to a request to enable a set of firmware features in the processing device, perform a validation process based on the key certificate, wherein the key certificate associates a first entity identifier with a firmware feature description file indicating the set of firmware features, wherein the first entity identifier is associated with a user entity;
- and
- countermeasure logic circuitry coupled with the authentication logic circuitry and configured to, in response to a violation detected during the validation process, enable a countermeasure in the processing device.
