USF Tampa Graduate Theses and Dissertations
We present an Intellectual Property (IP) protection technique for sequential circuits driven by embedding a decomposed signature into a Finite State Machine (FSM) through the manipulation of the arbitrary state encoding of the unprotected FSM. This technique is composed of three steps: (a) transforming the signature into a watermark graph, (b) embedding watermark graphs into the original FSM's State Transition Graph (STG) and (c) generating models for verification and extraction. In the watermark construction process watermark graphs are generated from signatures. The proposed methods for watermark construction are: (1) BSD, (2) FSD, and (3) HSD. The HSD method is shown …
