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 μm 2 . The area of all the Cells' is 0.025 m 2 , 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.

新的SCV方法在量子点细胞自动机中的实现

量子点细胞自动机(QCA)是一种新颖的纳米设备,可在纳米级实现逻辑电路。信息加密是纳米通信中的关键问题。本文提出了一种新的“选择,交叉,变异”(SCV)数据加密方法。这项工作还首次实现了此方法的QCA布局。基于QCA的SCV电路使用71个单元。该电路由六个多数门和两个反相器组成。的QCA电路的总面积为0.08μm 2 。所有单元的面积为0.025 m 2 ,占总面积的31.19%。电路延迟为1个时钟周期。另外,电路中不使用交叉线。将理论值与QCADesigner的仿真结果进行比较,可以验证电路的设计精度。估计了电路在热随机性下的计算能力,从而建立了所提出电路的稳定性。能量消耗的估计证明所提出的电路消耗非常低的能量。
