— 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)
— Production of cost-effective secure integrated chips, such as smart cards, requires hardware designers to consider tradeoffs in size, security, and power consumption. To design successful security-centric designs, the low-level hardware must contain built-in protection mechanisms to supplement cryptographic algorithms, such as advanced encryption standard(More)
