The National Institute of Standards and Technology (NIST) has narrowed down the field of potential post-quantum cryptography algorithms to 15 candidates, down from an initial 69 submissions. This marks the beginning of the third and final round of public review before NIST selects the algorithms that will form the basis of the first post-quantum cryptography standard.
The 15 remaining algorithms are divided into two tracks: seven “finalist” algorithms that appear to have the most promise for wide application, and eight “alternate” algorithms that may need more time to mature or are tailored to specific applications. NIST is asking experts to provide their input on these candidates in the report.
The new standard will specify quantum-resistant algorithms for digital signatures, public-key encryption, and key generation, augmenting existing standards. The review process will continue for about a year, with a deadline for comments, after which NIST plans to release the initial standard for quantum-resistant cryptography in 2022.
The potential impact of quantum computing on current cryptographic systems is significant, as quantum computers could easily solve many problems that are currently intractable for classical computers, potentially breaking many current cryptosystems. The development of post-quantum cryptography standards is therefore crucial to safeguarding sensitive information in the future.
