Integrated circuit personalisation

A system for configuring a plurality of integrated circuits, the system comprising:

• an integrated circuit interface configured to receive a plurality of integrated circuits, wherein each integrated circuit comprises a physical unclonable function and a memory storing data associated with a cryptographic key specific to the integrated circuit;
• a personalization file database comprising a plurality of encrypted files, wherein each encrypted file is encrypted with the cryptographic key specific to a respective one of the plurality of integrated circuits;
• and
• a processor configured to, for each encrypted file of the plurality of encrypted files:
• send the encrypted file to the respective integrated circuit;
• cause the respective integrated circuit to generate its cryptographic key using its data associated with the cryptographic key and its physical unclonable function;
• cause the respective integrated circuit to decrypt the encrypted file using its generated cryptographic key;
• and
• use the decrypted file to configure the respective integrated circuit.
