Embodiments are directed to provisioning a general-use basis for authentication of a processor device. During manufacture, a hardware processor stores a secret value and shares a derived value produced based on the secret value with a secure service. These values may be used in a limited-use initial authentication process to authenticate the hardware processor. A general-use basis for authentication not so limited as the initial authentication process is established subsequent to the manufacture of the hardware processor. The general-use basis for authentication may include a public-private key pair, and is established upon successful completion of the initial authentication process. Authentication using the general-use process produces an authentication traceable to the manufacture of the hardware processor.

Provisioning authentication keys in computer processor

Technologies for remote attestation include a group member device to generate a signature of a message using a cryptographic key assigned to the group member device by a group manager and determine an authentication path that indicates a plurality of cryptographic hashes necessary to compute a group public key of a group associated with a plurality of group member devices. The cryptographic key is assigned to the group member device based on a permutation of a set of cryptographic keys generated by the plurality of group member devices. The group member device transmits the signature and the authentication path to a verifier device for verification of the signature.
