Post-Quantum and Code-Based Cryptography—Some Prospective Research Directions

Cryptography has been used from time immemorial for preserving the confidentiality of data/information in storage or transit. Thus, cryptography research also evolving classical Caesar cipher to modern cryptosystems, based on modular arithmetic contemporary cryptosystems quantum computing. The emergence computing poses a major threat arithmetic, whereby even computationally hard problems which constitute strength ciphers could be solved polynomial time. This triggered post-quantum design and develop algorithms that can withstand attacks. paper provides an overview various directions have explored and, specifically, code-based dimensions explored. Some potential are yet perspective codes is key contribution this paper.
