The NIST Lightweight Cryptography Team has reviewed the finalists based on their submission packages, status updates, third-party security analysis papers, and implementation and benchmarking results, as well as the feedback received during workshops and through the lwc-forum. The decision was challenging since most of the finalists exhibited performance advantages over NIST standards on various target platforms without introducing security concerns.
The team has decided to standardize the Ascon family for lightweight cryptography applications as it meets the needs of most use cases where lightweight cryptography is required. Congratulations to the Ascon team! NIST thanks all of the finalist teams and the community members who provided feedback that contributed to the selection.
NIST’s next steps will be to:
NIST Lightweight Cryptography Team
Security and Privacy: lightweight cryptography
Activities and Products: standards development
