1. A method operational at an integrated circuit, the method comprising: powering ON a first volatile memory circuit to generate a plurality of initial logical state values, the first volatile memory circuit on the integrated circuit; deriving secret data based on the plurality of initial logical state values; storing the secret data in a secure volatile memory circuit, the secure volatile memory circuit secured by a secure execution environment (SEE); clearing the plurality of initial logical state values in the first volatile memory circuit; executing a cryptographic algorithm at the SEE to extract a secret key based on the secret data; and storing the secret key in the secure volatile memory circuit.
