The increasing advancement in quantum computing threatens the security of traditional cryptographic systems that underpin much of the modern world’s data protection. These systems rely heavily on the computational difficulty of problems like integer factorization (RSA) and elliptic curve discrete logarithms (ECC), which quantum computers could solve in polynomial time. As a result, there is an urgent need for cryptographic systems that remain secure even in the presence of quantum capabilities. Post-Quantum Cryptography (PQC) is the emerging field that aims to develop cryptographic protocols resistant to quantum-based attacks. This paper discusses the need for PQC, explores various candidate algorithms, reviews standardization efforts, and looks at the current challenges and future directions in the field.

Quantum computing poses a significant threat to conventional cryptographic systems that rely on the difficulty of mathematical problems such as integer factorization and discrete logarithms. These systems underpin much of the current security infrastructure, including public key cryptography and digital signatures. As quantum computers approach practical viability, there is an urgent need to transition to quantum-resistant cryptographic solutions that can secure digital communications against adversaries equipped with quantum capabilities. This paper explores the landscape of quantum-resistant cryptography, focusing on those algorithms that have emerged either as standards or as leading algorithm.

In the modern digital era, where cyber-attacks, data breaches, and digital spying threaten global security, conventional cryptographic systems face increasing challenges. The rapid development of quantum computing has amplified these threats by undermining the security foundations of classical encryption algorithms such as RSA (Rivest–Shamir–Adleman) and ECC (Elliptic Curve Cryptography), both of which depend on the computational hardness of factorization and discrete logarithmic problems. Quantum cryptography, rooted in the principles of quantum mechanics, introduces a transformative approach that ensures theoretically unbreakable security. This paper explores the theoretical foundations, current technological developments, challenges, and future prospects of quantum cryptography.

The emergence of quantum computing poses significant challenges and opportunities in the realm of cryptography. Traditional cryptographic algorithms, such as RSA and ECC (Elliptic Curve Cryptography), rely on the computational difficulty of certain mathematical problems, like factoring large integers and solving discrete logarithms. However, quantum computers leverage quantum mechanics to solve these problems in polynomial time, which could render many of today’s encryption techniques obsolete. This article examines the potential impact of quantum computing on modern cryptographic algorithms and explores quantum-safe cryptography alternatives that are being developed to withstand quantum attacks. We also discuss the readiness of quantum computers for real-world applications, their current limitations, and the future directions of quantum cryptography research.
