GENERATING A KEY DERIVED FROM A CRYPTOGRAPHIC KEY USING A PHYSICALLY UNCLONABLE FUNCTION

摘要

The embodiments relate to a method and a device for generating a key derived from a cryptographic key using at least one physically unclonable function. At least one request value is assigned to the cryptographic key and to at least one derivation parameter. A response value is generated on a circuit unit using the at least one physically unclonable function dependent on at least one respective request value. The derived key is derived from the at least one response value.
