Integrated circuit with parts activated based on intrinsic features

A fixed logic integrated circuit comprising:

• a unique code generator configured to generate a code having a value which is intrinsically unique to the integrated circuit, wherein the code is not transmitted outside the integrated circuit;
• an enrollment pattern generator configured to generate an enrollment pattern based on the unique code and encrypt the enrollment pattern into an encrypted form;
• wherein the integrated circuit is configured to transmit the enrollment pattern in the encrypted form to an external enrollment device and to receive enabling data from the external enrollment device, wherein the integrated circuit further comprises:
• a configuration file generator configured to generate configuration data using the enabling data and the unique code, subsequently perform an error check to determine whether to validate or invalidate the configuration data and generate an error signal when a determination to invalidate the configuration data is made;
• and
• a feature activation module configured to, in dependence upon the error check and the configuration data, perform each of the following:
• activate features of the integrated circuit when the configuration data is validated by the error check;
• disable features of the integrated circuit when the configuration data is invalidated as a result of the error check;
• and
• customize one or more features of the integrated circuit in dependence on the configuration data;
• a reset function configured to generate a reset signal in response to the error signal, and wherein the unique code generator, the enrollment pattern generator, the configuration file generator and the feature activation module are reset in response to the reset signal;
• wherein the unique code generator comprises a physical unclonable function and the enrollment pattern generator is configured to remove noise from the code.
