HARDWARE INTELLECTUAL PROPERTY PROTECTION THROUGH PROVABLY SECURE STATE-SPACE OBFUSCATION

摘要

The present disclosure describes exemplary methods and systems of protecting an integrated circuit. One exemplary method comprises receiving a plurality of key inputs for enabling operation of the integrated circuit; determining whether the received key inputs are correct key inputs for enabling operation of the integrated circuit; and if the received key inputs are determined to be incorrect key inputs, locking sequential logic and combinational logic of the integrated circuit until correct key inputs are received.
