Abstract

A method for key management in a field-programmable integrated part of an integrated circuit is disclosed herein. According to the method, a hardware configuration for the field-programmable integrated part is loaded into the field-programmable integrated part. The hardware configuration includes a key derivation functionality. Further, using the key derivation functionality, a cryptographic key is derived based on information provided in the field-programmable integrated part.
