NIST has selected 26 cryptographic algorithms as semifinalists for its post-quantum cryptography standardization project. These algorithms are considered the strongest candidates to protect electronic information from both conventional and quantum computer attacks. The algorithms will undergo a second round of review to evaluate their performance across various devices and systems.
The selected algorithms belong to three main families:
1. Lattice cryptosystems, which use geometric structures and mathematical arrays
2. Code-based systems, which rely on error-correcting codes
3. Multivariate systems, which depend on solving polynomial equations
NIST plans to announce post-quantum algorithms to supplement or replace three standards vulnerable to quantum attacks. The development of these algorithms will be influenced by the progress of quantum computer development, as many designers are focused on developing practical quantum computers.
