Abstract:
A methodology for requesting at least one signed security measurement from at least one module is provided. The methodology includes receiving the at least one signed security measurement from the at least one module; validating the at least one signed security measurement; generating a signed dossier including all validated signed security measurements in a secure enclave, the signed dossier being used by an external network device for remote attestation of the device.
