Abstract
Software or web application security is the main objective in the era of Information Technology (IT) and Artificial Intelligence (AI). Distinguishing proof of security at the initial stage produces significant results to comprehend the administration of security relics for best potential outcomes. A security alternative gives several methods and algorithms to ensure the software security. Security estimation is the vital factor in assessing, administrating, controlling security to improve the nature of security. It is to be realized that assessment of security at early stage of development helps in identifying distinctive worms, dangers, weaknesses and threats. This paper will talk about the definition and characterization of quantum computing in software security. For software security, we use different cryptography (methods or algorithms to secure our financial organizations, medical devices, military weapons, planes, ships, automobiles, navigators, etc. However, many cryptosystems are likely to collapse when the large quantum computer is developed. Recently, Google developed the Sycamore Processor 53 qubits. Such innovations indicate the advent of large quantum computer in future. Since cryptographic algorithm can be solved by the quantum computers, the present cryptosystem would be rendered obsolete. Hence, it is imperative to focus more on intensive research in the context of the present quantum cyber security. The main challenges in quantum era would be cryptography methods that fulfill the demands of security usability and flexibility without sacrificing the users' confidence. This research study, in particular, focuses on 'Software durability' which is a quality of security that alludes to the capacity to execution of an item on schedule. In the context of software and web application, a thorough assessment of security factors will significantly influence the software's durability in the era of quantum computing.
