Application of Quantum Algorithms for Network Protocols

Abstract

Cryptographic processes hold immense power in securing data transmissions across the Internet in the modern age. Preparing for future hacking possibilities is deemed essential and crucial to combat data breaches and leaks. With the advent of quantum computing, a field capable of performing complex operations within a short time, breaking into the cryptographic system keys with sheer brute force is visibly possible. This paper aims to create a framework that runs post-quantum cryptographic algorithms shortlisted by NIST for Round 3 on the TLS protocol. The framework is built using Python with the help of LibOQS packages, programmed to work as an API, and invoked with the help of a web application. It allows cross-platform execution as it is contained in a Docker container. The established framework utilizes digital signature cryptography to verify the authenticity of a signed message and key encapsulation mechanism (KEM) for secure communication between client and server. The algorithms can be integrated with various internet-based applications like IoT, blockchain, but the results are demonstrated using a web application for this research.
