The National Institute of Standards and Technology (NIST) has officially released NIST Special Publication 800-232, establishing the Ascon family of algorithms as the new standard for lightweight cryptography designed specifically for resource-constrained devices. Published in August 2025, this groundbreaking standard addresses critical security gaps in Internet of Things (IoT) devices, embedded systems, and low-power sensors […] The post NIST Publish ‘Lightweight Cryptography’ Standard To Protect IoT Devices appeared first on Cyber Security News.

The expression "Lightweight cryptography" reminds me of export ciphers. Hopefully the expression is the only similarity.

Export ciphers are unsafe algorithms used to comply with export control rules. Export ciphers introduced vulnerabilities that caused troubles decades later.

Lightweight cryptography selection by NIST was more transparent and security-focused. They accepted 57 candidates in a multi-round process. There was third party security analysis, discussion during workshops, and a report with results and references to published analysis.
