ABSTRACT:
Secure delivery of configuration data of an intellectual property (IP) core includes the steps of loading configuration data for the IP core into IP core space by an IP core provider, masking portions of the IP core space not loaded with configuration data in the loading configuration data step with the value 0 or 1 by the IP core provider, encrypting data in the IP core space by the IP core provider, loading configuration data for system design other than for the IP core into a remainder space and any unused portions of the IP core space by a system designer, masking portions of the IP core space loaded in the loading configuration data step with the value 0 or 1 used by the IP core provider in the masking portions of the IP core space not loaded step, and encrypting data in a configuration space by the system designer.
