NIST Publishes SP 800-232 | Ascon-Based Lightweight Cryptography Standards for Constrained Devices
August 13, 2025

NIST Publishes SP 800-232: Ascon-Based Lightweight Cryptography Standards for Constrained Devices.

This standard introduces a new Ascon-based family of symmetric-key cryptographic primitives that provides robust security, efficiency, and flexibility. With its compact state and range of cryptographic functions, it is ideal for resource-constrained environments, such as Internet of Things (IoT) devices, embedded systems, and low-power sensors. This standard includes multiple algorithms to meet a wide range of symmetric cryptographic needs, including the Authenticated Encryption with Associated Data (AEAD) scheme Ascon-AEAD128, the hash function Ascon-Hash256, and the eXtendable-Output Functions (XOFs) Ascon-XOF128 and Ascon-CXOF128.
