The National Institute of Standards and Technology announces the publication of NIST Internal Report (IR) 8268, Status Report on the First Round of the NIST Lightweight Cryptography Standardization Process. NIST is selecting one or more authenticated encryption and hashing schemes suitable for constrained environments through a public, competition-like process.
In February 2019, 57 candidate algorithms were submitted for consideration. Among these, NIST accepted 56 as first-round candidates in April 2019, marking the beginning of the first round of the NIST Lightweight Cryptography Standardization Process.
Due to the large number of submissions and the short timeline of the process, NIST said it decided to eliminate some of the algorithms from consideration early in the first evaluation phase to better focus analysis on the more promising submissions.
NIST’s report outlines the evaluation criteria and selection process based on public feedback and internal review of the first-round candidates and provides the list of 32 candidate algorithms selected for the second round of the evaluation process.
