An integrated circuit and a method of configuring a plurality of integrated circuits are disclosed. Each integrated circuit comprises a cryptographic key specific to it. Each integrated circuit comprises a cryptographic key specific to it. Each cryptographic key can be generated on the respective integrated circuit using a physical unclonable function and data associated with the cryptographic key, e.g. a configuration message comprising instructions for generating the cryptographic key using the physical unclonable function. The cryptographic key specific to the integrated circuit is not stored on the integrated circuit. Each of the plurality of integrated circuits are configured using a data file that is encrypted with the respective cryptographic key specific to the integrated circuit, circuit.
