Secure key storage using physically unclonable functions

Abstract

Some implementations disclosed herein provide techniques and arrangements for provisioning keys to integrated circuits/processor/apparatus. In one embodiment, the apparatus includes a physically unclonable functions (PUF) circuit to generate a hardware key based on at least one manufacturing variation of the apparatus and a nonvolatile memory coupled to the PUF circuit, the nonvolatile memory to store an encrypted key, the encrypted key comprising a first key encrypted using the hardware key. The apparatus further includes a hardware cipher component coupled to the nonvolatile memory and the PUF circuit, the hardware cipher component to decrypt the encrypted key stored in the nonvolatile memory with at least the hardware key to generate a decrypted copy of the first key and fixed logic circuitry coupled to the PUF circuit and the hardware cipher component, the fixed logic circuitry to verify that the decrypted copy of the first key is valid.
