The present disclosure describes systems, apparatuses, and methods for obfuscation-based intellectual property (IP) watermark labeling. One such method comprises identifying, by one or more computing processors, a specific net within an integrated circuit design that is likely to be used in a malicious attack; and adding additional nets to the integrated circuit design that add additional logic states to a finite state machine present in the integrated circuit design. The additional logic states comprise watermarking states for performing authentication of the integrated circuit design, in which a watermark digest can be captured upon application of secret key inputs to the additional nets. Other methods, systems, and apparatuses are also presented.

Framework for obfuscation based watermarking

Embodiments of the present disclosure provide methods, apparatus, and computer program products for generating an insertion netlist for a target circuit configured for inserting a malicious design alteration into the circuit based on a design identifying reference trigger nets. Features are extracted for each net identified in a netlist for the circuit. A set of reference trigger features is generated for each of the reference trigger nets. A net is selected from the netlist for each set of reference trigger features based on a similarity between the features of the net and the set of reference trigger features. The insertion netlist is generated that includes the circuit with the malicious design alteration inserted at each of the selected nets.
