Abstract
Embodiments of electronic circuits enable security of sensitive data in a design and manufacturing process that includes multiple parties. An embodiment of an electronic circuit can include a private key embedded within the electronic circuit that is derived from a plurality of components including at least one component known only to the electronic circuit and at least one immutable value cryptographically bound into messages and residing on the electronic circuit, public key generation logic that generates a public key to match the private key, and message signing logic that signs messages with the private key.
