Abstract

When the rate of technological advancement is considered, it is clear that a Post-Quantum World is inevitable. Trying to prevent or delay the advancement of Quantum Technology is not the answer as it could be the silver lining to today’s science fictional ideology such as achieving speed of light, time traveling and also the next level of machine learning. But it will be the demise of all cryptosystems available today. The only solution available is to evolve, adopt and adapt to Post-Quantum Cryptosystems. The intention of this paper is to provide an insight on the probable scenarios that may occur in a Post-Quantum world, the solutions for arising issues and to provide our own input in how to manage such technology with the main focus on cryptography.
