Abstract
Disclosed is a method for providing a public key for authenticating an integrated circuit. In the method, the integrated circuit obtains a hardware key and an integrated circuit identifier. The integrated circuit generates a derived key based on the hardware key using a key derivation function (KDF) shared with a manufacturing machine. The integrated circuit generates a private key and a corresponding public key using the derived key as an input to a deterministic function. The integrated circuit then provides the public key and the integrated circuit identifier to a partner service for authentication of the integrated circuit using an anonymized credential database to be provided to the partner service by a manufacturer.
