Abstract
Various examples relate to an apparatus, a device, a method, and a computer program for a computing device, for providing a certificate chain, and to a computing device. An apparatus comprises processor circuitry to obtain information on an identity of a firmware being used to operate the computing device, generate a leaf certificate for the firmware being used to operate the computing device based on the identity of the firmware being used to operate the computing device and using an intermediate certificate being generated based on an identity of a firmware having been used during a cold boot of the computing device, and provide a certificate chain comprising the leaf certificate for an external verifier.
Claims18
An apparatus for a computing device, the apparatus comprising interface circuitry, machine-readable instructions, and processor circuitry to execute the machine-readable instructions to:
- obtain information on an identity of a firmware being used to operate the computing device;
- generate a leaf certificate for the firmware being used to operate the computing device based on the identity of the firmware being used to operate the computing device and using an intermediate certificate being generated based on an identity of a firmware having been used during a cold boot of the computing device;
- and
- provide a certificate chain comprising the leaf certificate for an external verifier.
A method for a computing device, the method comprising:
- obtaining information on an identity of a firmware being used to operate the computing device;
- generating a leaf certificate for the firmware being used to operate the computing device based on the identity of the firmware being used to operate the computing device and using an intermediate certificate being generated based on an identity of a firmware having been used during a cold boot of the computing device;
- and
- providing a certificate chain comprising the leaf certificate for an external verifier.
