Abstract
Embodiments of methods of provisioning an electronic circuit enable security of sensitive data in a design and manufacturing process that includes multiple parties. In an illustrative embodiment, a method of provisioning an electronic circuit includes generating at least one secret value, embedding the at least one secret value into the electronic circuit, programming into the electronic circuit a private key derivation function that derives the private key from the at least one secret value and a trust anchor, and programming into the electronic circuit a public key generation function that generates a public key matching the private key. The method can further include receiving for execution trust anchor-authenticated logic that contacts a predetermined actor of the plurality of distinct actors and communicates to the predetermined actor a message signed with the private key.
