The National Institute of Standards and Technology (NIST) has finalized a lightweight cryptography standard to protect even the smallest networked devices from cyberattacks.

Published as Ascon-Based Lightweight Cryptography Standards for Constrained Devices (NIST Special Publication 800-232), the standard offers tools for securing data created and transmitted by billions of IoT devices, along with other small electronics such as RFID tags and medical implants.
