IMPACT OF QUANTUM COMPUTING ON APPLICATION SECURITY AND VULNERABILITIES

Abstract

Quantum computing represents a paradigm shift in computational capability, threatening to undermine classical cryptographic systems that underpin modern application security. This paper analyzes vulnerabilities introduced by quantum algorithms such as Shor’s and Grover’s, which jeopardize widely used encryption standards like RSA, ECC, and AES. It evaluates post-quantum cryptography (PQC) solutions, including lattice-based and hash-based cryptosystems, and explores their integration into software development lifecycles. The study also assesses quantum-enhanced security mechanisms like Quantum Key Distribution (QKD) and examines regulatory challenges in standardizing quantum-safe protocols. Synthesizing technical insights and empirical data up to September 2022, this research emphasizes the urgency of adopting quantum-resilient frameworks to mitigate future risks.
