An Investigative Study on Variants of Post-Quantum RSA

Abstract

As quantum computing advances, traditional cryptographic schemes such as RSA face increasing vulnerability to attacks. This investigative study delves into the realm of post-quantum cryptography, focusing specifically on variants of RSA designed to resist quantum attacks. Through a comprehensive review of existing literature and cryptographic protocols, we analyse the strengths and weaknesses of various post-quantum RSA variants, including lattice-based, code-based, and hash-based approaches. Additionally, we evaluate the computational efficiency and security guarantees of these variants, considering factors such as key size, encryption/decryption speed, and resistance to quantum algorithms. Our findings provide insights into the current state of post-quantum RSA, highlighting promising directions for further research and development in the quest for quantum-resistant cryptographic solutions. In the future robust variants of RSA, algorithms will help the stakeholders of the cryptosystems to instil faith in the security of the system in the face of challenges which is inadvertently posed by the attackers using advanced security attack vectors.
