Abstract
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.
