DECOR introduces a randomized algorithm to alter UDC cofactors in locked circuits, creating one-to-many and many-to-one mappings for keys. Experimental results show a substantial decrease in key prediction accuracy with negligible advantage over random guessing. The method is applicable to various logic locking schemes and exhibits acceptable area overhead.
