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 subgraph 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)
Reversible logic is widely being considered as the potential logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on physical entropy. Recent advances in reversible logic allow for improved quantum computer algorithms and schemes for corresponding computer architectures. Significant contributions have been(More)

Quantum mechanical principles that govern the basic laws of physics increasingly limit CMOS operation with transistor scaling. Traditional logic based CMOS circuits cannot achieve ultra-low power levels due to heat dissipated for a single bit loss of information as represented by the Landauer barrier. Reversible logic is a promising computing paradigm(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)
