ABSTRACT

The advent of quantum computing represents a significant challenge to modern cryptography, particularly in the realm of public key cryptosystems. This paper explores the potential implications of quantum computers on current cryptographic techniques, focusing on how quantum algorithms, such as Shor’s algorithm, could render widely used encryption methods like RSA and Elliptic Curve Cryptography vulnerable. It also examines the role of quantum key distribution (QKD) in maintaining secure communication in a post-quantum world and discusses the importance of developing quantum-resistant cryptographic algorithms. As quantum computing progresses, the need for post-quantum cryptography becomes increasingly urgent to ensure the continued security of digital information.

Keywords: Quantum Computing, Cryptography, Public Key Cryptosystems, Quantum Key Distribution (QKD), Shor’s Algorithm.
