Abstract:
Embodiments include methods for securely provisioning copies of an electronic circuit. A first entity embeds one or more secret values into copies of the circuit. A second entity: 1) embeds a trust anchor in a first copy of the circuit; 2) causes the circuit to generate a message signing key pair using the trust anchor and the embedded secret value(s); 3) signs provisioning code using a code signing private key; and 4) sends a corresponding code signing public key, the trust anchor, and the signed provisioning code to a third entity. The third entity embeds the trust anchor in a second copy of the circuit and causes the circuit to: 1) generate the message signing private key; 2) verify the signature of the signed provisioning code using the code signing public key; and 3) launch the provisioning code on the circuit.
