NIST is currently reviewing Special Publication (SP) 800-106, "Randomized Hashing for Digitial Signatures," (2009) and is requesting public feedback on all aspects of the publication by March 16, 2022.

NISTIR 8369 describes the evaluation process and selection process used during the second round of the NIST Lightweight Cryptography Standardization Process. Ten finalists were announced in March 2021.

NIST has published Special Publication (SP) 800-208, "Recommendation for Stateful Hash-Based Signature Schemes."

NIST currently intends to approve both LMS and XMSS stateful hash-based signature schemes, and is seeking public comments on that proposed action by April 1, 2019.

NIST has published "Blockchain Technology Overview," NIST Internal Report (NISTIR) 8202. This is a high-level technical publication that examines the history, scope, and characteristics of this emerging technology which has...

NIST's Computer Security Division is seeking input on the development of standards for stateful hash-based signatures, including XMSS (see IETF RFC 8391).

"A Data Structure for Integrity Protection with Erasure Capability" is a draft white paper available for public comment until August 3, 2018. It describes a "block matrix" data structure .

In 2005 Prof. Xiaoyun Wang announced a differential attack on the SHA-1 hash function. NIST found that the attack was practical, and announced plans for transitioning to SHA-2 algorithms and development of SHA-3.

Researchers have recently announced they have discovered a new way to break a number of cryptographic hash algorithms. Click here to read NIST's brief comments on recent cryptanalytic attacks on secure hashing functions and...
