What Is Post Quantum Cryptography? And Other Questions…

New to quantum computing? Familiar but haven’t looked back at some of the basic goings-on? This piece from QANplatform provides a refresher of the NIST post-quantum standardization effort. Worth the read from the source, below. Because Quantum is Coming. Qubit.

Creating A Quantum-Proof Future

Points to note ~

+  Towards the end of 2016, the National Institute of Standards and Technology (NIST) initiated a program aimed at developing and identifying quantum hard public-key cryptographic algorithms. NIST is a non-regulatory agency of the United States Department of Commerce whose mission is to promote innovation and industrial competitiveness through science and innovation. The agency provides guidelines on global standards with regards to certain areas of science, with cryptography being one.

+  The post-quantum crypto project encouraged submissions from any parties who had developed or were in the process of creating algorithms that qualify as quantum-safe. The agency planned to sift through the submissions, employing the wisdom of the masses to uncover algorithms that can usher the world into a new age of quantum, safety.

Ring lattice-based cryptography is considered to be the most promising path to QP cryptography

What is post-quantum cryptography?

+  Post-quantum cryptography is defined as the study of cryptosystems which can be executed on a classical computer or a super computer but remain secure even when running on a quantum computer. The goal is not to make classical computers obsolete by creating algorithms that are not backward compatible. This would be infeasible and lead to a crisis in and of itself.

+  Instead, as NIST explains: “The goal of post-quantum cryptography (also called quantum-resistant cryptography) is to develop cryptographic systems that are secure against both quantum and classical computers, and can interoperate with existing communications protocols and networks.”
