NDLI: Implementation of the new SCV method in quantum-dot cellular automata

Content Provider	IET Digital Library
Author	Yu, Chen Wang, Lei Xie, Guangjun
Abstract	Quantum-dot cellular automata (QCA) is a novel nanodevice that implements logic circuits at the nanoscale. Information encryption is a key issue in nanocommunications. This article proposes a new method ‘select, cross, variation’ (SCV) for data encryption. This work also implements the QCA layout of this method for the first time. The QCA-based SCV circuit uses 71 cells. The circuit is composed of six majority gates and two inverters. The total area of the QCA circuit is 0.08 μm2. The area of all the Cells' is 0.025 m2, accounting for 31.19% of the total area. The circuit delay is 1 clock cycle. In addition, no cross wires are used in the circuit. Comparing the theoretical values with the simulation results of QCADesigner, the design accuracy of the circuit is verified. The circuit's computational capabilities under thermal randomness is estimated, thus establishing the stability of the proposed circuit. The estimation of energy dissipation proves that the proposed circuit consumes very low energy.
