OVERVIEW

Draft FIPS 203, FIPS 204 and FIPS 205, which specify algorithms derived from
CRYSTALS-Dilithium, CRYSTALS-KYBER and SPHINCS+, were published August 24,
2023.  The public comment period will close November 22, 2023.

PQC License Summary & Excerpts


BACKGROUND

NIST initiated a process to solicit, evaluate, and standardize one or more
quantum-resistant public-key cryptographic algorithms.  Full details can be
found in the Post-Quantum Cryptography Standardization page.  

In recent years, there has been a substantial amount of research on quantum
computers – machines that exploit quantum mechanical phenomena to solve
mathematical problems that are difficult or intractable for conventional
computers. If large-scale quantum computers are ever built, they will be able to
break many of the public-key cryptosystems currently in use. This would
seriously compromise the confidentiality and integrity of digital communications
on the Internet and elsewhere.  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. 

The question of when a large-scale quantum computer will be built is a
complicated one. While in the past it was less clear that large quantum
computers are a physical possibility, many scientists now believe it to be
merely a significant engineering challenge. Some engineers even predict that
within the next twenty or so years sufficiently large quantum computers will be
built to break essentially all public key schemes currently in use.
Historically, it has taken almost two decades to deploy our modern public key
cryptography infrastructure.  Therefore, regardless of whether we can estimate
the exact time of the arrival of the quantum computing era, we must begin now to
prepare our information security systems to be able to resist quantum computing.
