Crypto Publication Review Project

Overview

This project summarizes NIST’s current and planned activities for reviewing its cryptography standards and other publications. The Crypto Publication Review Board (“the Board”) within the Computer Security Division identifies a publication for review based on its original publishing date and any relevant issues raised since it was published. The targeted review period for each publication is every five years. The Board welcomes public comments on the publications under review and will consider those comments as it develops a proposal for processing each publication.
