Hamood, Marwa M., Moosa, Arwa A.
The emergence of quantum computers, coupled with relentless advancements in technology, calls for the immediate transition from classical to modern cryptography for efficient data transfer across optic fibers. This paper assesses different proposed post-quantum signature schemes pertaining to their plausibility of being useful against quantum computers’ capabilities. The ability of quantum computers to solve mathematical equations at speeds significantly faster than those of classical computers is remarkable. Existing cryptographic frameworks that depend on discrete logarithms and integer factorization are seriously threatened by this exceptional efficiency. In order to protect sensitive data in a post-quantum world, it may be necessary to reevaluate existing encryption techniques as the introduction of quantum computing has the potential to seriously compromise the security of many popular cryptographic systems. Hence, during the post-quantum epoch, the implementation of cryptographic measures to safeguard the confidentiality, integrity, and authenticity of all data amid the challenges instigated by quantum computers is an undertaking that must be addressed tactically and strategically. This document endeavors to depict the state-of-the-art methodologies in post-quantum cryptography outlining lattice, hash, code, and multivariate polynomial lattice-based schemes. By discussing their advantages, disadvantages, and implementation hurdles, this work seeks to educate academics and industry experts about the steps that must be taken to safeguard digital communications in the age of quantum technology.
