NIST has initiated a process to solicit, evaluate, and standardize lightweight cryptographic algorithms that are suitable for use in constrained environments where the performance of current NIST cryptographic standards is not acceptable.
In recent years, there has been increased demand for cryptographic standards that are tailored for constrained devices. NIST has decided to create a portfolio of lightweight cryptographic algorithms, designed for limited use in applications and environments where cryptographic operations are performed by constrained devices that are unable to use existing NIST standards.
Candidate algorithm nominations may be submitted until February 25, 2019. Complete instructions for submitting candidate packages—including minimal acceptability requirements—are available on the Lightweight Cryptography project page on CSRC (below).
