| Popis: | The limits and difficulties looked by CMOS innovation in the nano system has prompted the exploration of other potential advancements which can work with same functionalities anyway with lower power scattering and higher speed. One such technology is Quantum dot Cellular Automata (QCA). In this paper, QCA is explored to design the authentication system. This paper first presents the basic operating principle of a Fingerprint Authentication System (FAS) followed by fault tolerance analysis of four efficient XOR gate designs in the literature. The XOR gate is then used in the proposed four fault tolerant designs of reversible FAS in QCA, which are based on different reversible gates. Based on the evaluation of different performance parameters, it is seen that the proposed FAS designs are cost efficient and achieve improvement up to 59.46% in terms of number of cells, 67.16% improvement in cell area, 67.14% improvement in total area, 66.67% improvement in latency and 90.51% improvement in terms of circuit cost from the existing design Furthermore, the energy dissipation examination of the proposed designs is also additionally introduced. Subsequently, the proposed designs can be effectively used in biometric applications demanding ultra-low power consumption, higher operating speed and minimal area utilization. |
