Recommendation for Random Bit Generator (RBG) Constructions

September 25, 2025
Author(s)
Elaine Barker, John Kelsey, Kerry McKay, Allen Roginsky, Meltem Sonmez Turan
The NIST Special Publication (SP) 800-90 series of documents supports the generation of high-quality random bits for cryptographic and non-cryptographic use. SP 800-90A, Recommendation for Random Number Generation Using Deterministic Random Bit Generators

NIST Special Publication 800-227, Recommendations for Key-Encapsulation Mechanisms

September 18, 2025
Author(s)
Gorjan Alagic, Elaine Barker, Lidong Chen, Dustin Moody, Angela Robinson, Hamilton Silberg, Noah Waller
A key-encapsulation mechanism (KEM) is a set of algorithms that can be used by two parties under certain conditions to securely establish a shared secret key over a public channel. A shared secret key that is established using a KEM can then be used with

Guide to IPsec VPNs

June 30, 2020
Author(s)
Elaine B. Barker, Quynh H. Dang, Sheila E. Frankel, Karen Scarfone, Paul Wouters
Internet Protocol Security (IPsec) is a widely used network layer security control for protecting communications. IPsec is a framework of open standards for ensuring private communications over Internet Protocol (IP) networks. IPsec configuration is

Recommendation for Cryptographic Key Generation

June 4, 2020
Author(s)
Elaine B. Barker, Allen L. Roginsky, Richard Davis
Cryptography is often used in an information technology security environment to protect data that is sensitive, has a high value, or is vulnerable to unauthorized disclosure or undetected modification during transmission or while in storage. Cryptography

Recommendation for Key Management: Part 1 - General

May 4, 2020

Recommendation for Cryptographic Key Generation

July 23, 2019
Author(s)
Elaine B. Barker, Allen L. Roginsky
Cryptography is often used in an information technology security environment to protect data that is sensitive, has a high value, or is vulnerable to unauthorized disclosure or undetected modification during transmission or while in storage. Cryptography

Recommendation for Pair-Wise Key Establishment Using Integer Factorization Cryptography

March 21, 2019
Author(s)
Elaine B. Barker, Lidong Chen, Allen L. Roginsky, Richard Davis, Scott Simon
This Recommendation specifies key-establishment schemes using integer factorization cryptography (in particular, RSA). Both key-agreement and key transport schemes are specified for pairs of entities, and methods for key confirmation are included to

Transitioning the Use of Cryptographic Algorithms and Key Lengths

March 21, 2019
Author(s)
Elaine B. Barker, Allen L. Roginsky
The National Institute of Standards and Technology (NIST) provides cryptographic key management guidance for defining and implementing appropriate key management procedures, using algorithms that adequately protect sensitive information, and planning ahead

Recommendation for the Entropy Sources Used for Random Bit Generation

January 10, 2018
Author(s)
Meltem Sonmez Turan, Elaine B. Barker, John M. Kelsey, Kerry A. McKay, Mary L. Baish, Mike Boyle
This Recommendation specifies the design principles and requirements for the entropy sources used by Random Bit Generators, and the tests for the validation of entropy sources. These entropy sources are intended to be combined with Deterministic Random Bit
