The U.S. National Institute of Standards and Technology (NIST) has announced that a family of authenticated encryption and hashing algorithms known as Ascon will be standardized for lightweight cryptography applications.

"The chosen algorithms are designed to protect information created and transmitted by the Internet of Things (IoT), including its myriad tiny sensors and actuators," NIST said. "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."
Put differently, the idea is to adopt security protections via lightweight cryptography in devices that have a "limited amount of electronic resources."

Ascon is credited to a team of cryptographers from the Graz University of Technology, Infineon Technologies, Lamarr Security Research, and Radboud University.

The suite comprises authenticated ciphers ASCON-128, ASCON-128a, and a variant called ASCON-80pq that comes with resistance against quantum key-search. It also offers a set of hash functions ASCON-HASH, ASCON-HASHA, ASCON-XOF, and ASCON-XOFA.

Lightweight electronics, meet the heavyweight champion for protecting your information: Security experts at the National Institute of Standards and Technology (NIST) have announced a victor in their program to find a worthy defender of data generated by small devices. The winner, a group of cryptographic algorithms called Ascon, will be published as NIST’s lightweight cryptography standard later in 2023.
