NIST Selects ‘Lightweight Cryptography’ Algorithms to Protect Small Devices
The winner, a group of cryptographic algorithms called Ascon, will be published as NIST’s lightweight cryptography standard later in 2023. The chosen algorithms are designed to protect information created and transmitted by the Internet of Things (IoT), including its myriad tiny sensors and actuators. They are also designed for other miniature technologies such as implanted medical devices, stress detectors inside roads and bridges, and keyless entry fobs for vehicles. Devices like these need “lightweight cryptography” — protection that uses the limited amount of electronic resources they possess.
