- Abstract
Using cryptography correctly is crucial in the current situation to safeguard data and ensure data security during data transfer. In this digital era, messages must be appropriately encrypted and decoded to prevent data misuse and ensure its accessibility to the intended recipient. Conventional cryptography techniques mostly depend on the mathematical intricacy of the encoding functions and the shared key. One such encoding approach that we may take into consideration is the Vigenere cipher algorithm. In this study, we want to apply this strategy utilizing reversible logic with the assistance of two helpful tools, namely, IBM Quantum (IBMQ) and QCADesigner. The encoder and decoder circuits for the Vigenere cipher are therefore proposed in this work in QCADesigner by utilizing Peres and DG gates in quantum-dot cellular automata (QCA) that consist of a single layer with 42 cells for encryption and 47 cells for decryption. The proposed circuit outperforms the existing ones concerning area, cell count and latency. Given that the layouts' energy consumption is assessed, it is guaranteed that the QCA nanodevice might serve as a stand-in platform for the creation of reversible circuits. The same simulation outcome was also obtained while building the identical circuits in a quantum presentation using IBMQ. The two applications are closely connected and both rely on quantum concepts. The outcomes are therefore verified for each of the two situations. The reversible Vigenere cipher technique enhances data security. Further sophisticated low-power nanoscale lossless nanocommunication architecture may be created with the help of the suggested circuits. In this article we first designed reversible gates, Peres gate and DG gate in Quantum Dot Cellular Automata (QCA) and the same in IBMQ. Using these two gates we achieve the reversible vigenere cipher. Encoder and decoder circuit is designed to achieve this.
