Analysis of Quantum Cryptology and the RSA Algorithms Defense Against Attacks Using Shor’s Algorithm in a Post Quantum Environment

Over the course of the previous twenty years, quantum cryptanalysis has become an important topic of research. The development of two well-known algorithms one for speedier factoring and the other for quicker searching has brought about a change in the conventional technique of computation. These algorithms are responsible for the change. A great number of the algorithms that were used in the conventional way of computing were really risk-free, precise, speedy, and output-oriented. In the post-quantum environment, it is absolutely necessary to investigate the behaviour of various classical algorithms when they are under attack. The behaviour of the RSA algorithm in terms of its resilience to attacks is the subject of investigation in this work. Deciphering the RSA codes requires the application of the Shor algorithm. In order to conduct the experiment, both the Qiskit simulator and the IBM quantum environment are utilised. The amount of qubit capacity now available is the primary determinant of how simple it is to break the RSA algorithm. One can draw the conclusion that the capacity of any quantum computer to decode RSA codes is directly dependent on the number of bits used in those codes.
