Recently, Quantum-dot Cellular Automata (QCA) based reversible logic circuit has an
enormous benefit over CMOS based logic circuit. As a promising technology for
Nanoelectronics computing, reversible-QCA has gained more and more attention from
researchers around the world. In this paper, a reversible authenticator circuit based on
QCA was implemented. This article presents a Nano-authenticator circuit to verify the
authenticated and unauthenticated inputs. The proposed QCA designs have been
implemented in a different manner from existing designs, which are primarily based on a
coplanar design approach. The efficiency of QCA design has been investigated based on
parameters such as cell count, area, and latency. Furthermore, missing an additional cell
defect of the reversible authenticator has been analyzed, and covers the fault tolerance of
60.41% and 75%, respectively. In addition, the proposed Feynman gate in QCA
environment achieves 76.35% area, 12.5% cell count and 95.55% average energy
dissipation improvement as compared to the existing layout. Moreover, the new reversible
authentication circuit achieves 87.75% cost and 43.54% area improvement in comparison
with the previous state-of-art design.
