— We propose a novel technique to watermark sequential circuits by embedding a signature via state encoding. The proposed technique is a greedy heuristic for the sub-graph matching problem, which has two steps: (a) watermark graph construction and (b) watermark embedding in the State Transition Graph of the FSM. Due to combinatorial complexity, reverse(More)
