Unbreakable Security in a Quantum Age: A Systematic Literature Review on Post-Quantum Lattice-Based Standards

Abstract

The rapid advances in the field of quan-tum computing have led to a concern in the cryp-tographic security implemented in already existing systems. This has led to an increasing interest in the search for post quantum alternatives which are capable of withstanding attacks in the future era of quantum computers. Out of the many approaches that have been put forward, the most promising candidates belong to the class of lattice based cryptography due to their efficient parameter sizes and performances. The robustness of these post quantum schemes have been tested by considering the evaluation criteria which have been put forward by NIST to ensure that the security guarantee provided by these proposed systems are absolute. This paper provides an overview of the various lattice based cryptosystems that have been selected as candidates for standardization by NIST and a comparison between them has been provided demonstrating the differences in their performances on various platforms. © 2023 IEEE.
