Combinatorial methods reduce costs for testing, and have important applications in software engineering: Combinatorial or t-way testing is a proven method for better testing at lower cost. The key insight underlying its effectiveness resulted from a series of studies by NIST from 1999 to 2004. NIST research showed that most software bugs and failures are caused by one or two parameters, with progressively fewer by three or more, which means that combinatorial testing can provide more efficient fault detection than conventional methods. Multiple studies have shown fault detection equal to...

The purpose of the United States Government Configuration Baseline (USGCB) initiative is to create security configuration baselines for Information Technology products widely deployed across the federal agencies. The USGCB baseline evolved from the Federal Desktop Core Configuration mandate. The USGCB is a Federal Government-wide initiative that provides guidance to agencies on what should be done to improve and maintain an effective configuration settings focusing primarily on security.

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. Publications Under Review...

Optimization of circuits leads to efficiency improvement in a wide range of algorithms and protocols, such as for symmetric-key and public-key cryptography, zero-knowledge proofs and secure multi-party...

Welcome to the CMVP The Cryptographic Module Validation Program (CMVP) is a joint effort between the National Institute of Standards and Technology under the Department of Commerce and the Canadian Centre for Cyber Security, a branch of the Communications Security Establishment. The goal of the CMVP is to promote the use of validated cryptographic modules and provide Federal agencies with a security metric to use in procuring equipment containing validated cryptographic modules. CMVP has over 1,000 validated modules that are currently active, with over 5,000 modules validated since the...

NIST has traditionally published secure configuration guides for Apple operating systems, e.g., NIST SP 800-179. The macOS Security Compliance Project (mSCP) seeks to simplify the macOS security development cycle by reducing the amount of effort required to implement security baselines. This collaboration between federal organizations minimizes the duplicate effort that would be required to administer individual security baselines. Additionally, the secure baseline content provided is easily extensible by other parties to implement their own security requirements. The latest recommended...

A main goal of circuit masking is to make more difficult the illegitimate exfiltration of secrets from a circuit evaluation. Masked Circuits (MC) can be produced by masking schemes, which use secret-sharing of the input bits and recompile the circuit logic to ensure that important properties of the secret sharing remain across the circuit evaluation. The MC project is on hold, but a future step will gather masked circuits. Updates will be announced via the MC-forum. After past exploratory steps to obtain feedback, the Masked Circuits (MC) project will not be considering actions toward...

Publications that discuss the generation, establishment, storage, use and destruction of the keys used NIST’s cryptographic algorithms Project Areas: Key Management Guidelines Key Establishment Cryptographic Key Management Systems Generally-speaking, there are two types of key establishment techniques: 1) techniques based on asymmetric (public key) algorithms, and 2) techniques based on symmetric (secret key) algorithms. However, hybrid techniques are also commonly used, whereby public key techniques are used to establish symmetric (secret) key encryption keys, which are then used to...

NIST maintains the National Checklist Repository, which is a publicly available resource that contains information on a variety of security configuration checklists for specific IT products or categories of IT products. A security configuration checklist (also called a lockdown, hardening guide, or benchmark) is a series of instructions or procedures for configuring an IT product to a particular operational environment, for verifying that the product has been configured properly, and/or for identifying unauthorized changes to the product. The IT product may be commercial, open source,...

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics (On-demand self-service, Broad network access, Resource pooling, Rapid elasticity, Measured Service); three service models (Cloud Software as a Service (SaaS), Cloud Platform as a Service (PaaS), Cloud...

The multi-party paradigm of threshold cryptography enables threshold schemes, which apply principles of secure multiparty computation (MPC) to achieve protocols that enable a secure distribution of trust in the operation of cryptographic primitives. Threshold schemes can be applied to NIST standardized primitives/schemes, and beyond. The technical scope of the MPTC-project includes threshold schemes (for signatures, public-key encryption/decryption, ciphers, hashing, fully-homomorphic encryption (FHE), and key-generation), as well as auxiliary techniques (such as zero-knowledge proofs (ZKP)...
