Another nanotechnology model called QCA,
or ”Quantum Dot-Cellular Automata,” provides an
alternative solution for CMOS, which has a lot of
hardware limitations and a lot of real cutoff points. Data
is passed based on electron charge and by their shared
electrostatic repugnance in QCA, a semiconductor-free
innovation. The device thickness, exchanging speed timing, and force utilisation of QCA are remarkably higher.
QCA circuits may play a big role in cryptographic
applications. Using a QCA-based rationale circuit,
encryption and decryption operations are carried out.
The research paper illustrates a fundamental QCA
cypher text creation method that could be helpful for
secure QCA-based nano-communication. Finding a
practical so-lution for secured authentication is the focus
of secured encryption. Using the QCA Designer-2.0.3
tool, the results are executed and tested.
