Blockchain for Access Control Systems

May 26, 2022

Author(s)

Vincent C. Hu

The rapid development and wide application of distributed network systems have made network security – especially access control and data privacy – ever more important. Blockchain technology offers features such as decentralization, high confidence, and

A Data Structure for Integrity Protection with Erasure Capability

May 20, 2022

Author(s)

D. Richard Kuhn

This document describes a data structure, referred to as a data block matrix, that supports the ongoing addition of hash-linked records while also allowing for the deletion of arbitrary records, thereby preserving hash-based integrity assurance that other

CMVP Approved Sensitive Security Parameter Generation and Establishment Methods: CMVP Validation Authority Updates to ISO/IEC 24759

May 20, 2022

Author(s)

Kim B. Schaffer, Alexander Calis

The approved sensitive security parameter generation and establishment methods listed in this publication replace the ones listed in ISO/IEC 19790 Annex D and ISO/IEC 24759 paragraph 6.16, within the context of the Cryptographic Module Validation Program

Improving quantum state detection with adaptive sequential observations

May 13, 2022

Author(s)

Emanuel Knill, Scott Glancy, Daniel Cole, Shawn Geller

For many quantum systems intended for information processing, one detects the logical state of a qubit by integrating a continuously observed quantity over time. For example, ion and atom qubits are typically measured by driving a cycling transition and

A Historical Note on Shell Sort, Bresenham's Algorithm, and the Chinese Postman Problem

May 6, 2022

Author(s)

Paul E. Black

These are historical notes, from those involved, on the names and origins of Shell sort, Bresenham's Algorithm, and the Chinese Postman Problem.

Generating Cyber-Physical System Risk Overlays for Attack and Fault Trees using Systems Theory

April 28, 2022

Author(s)

Matthew Jablonwski, Duminda Wijesekera, Anoop Singhal

We describe a formalized systems theoretic method for creating cyber-physical system (CPS) risk overlays that augment existing tree-based models used in CPS risk and threat analysis processes. This top-down approach objectively scopes the system's threat

DeepFit: automated distribution fitting for building stochastic modelsDeepFit: automated distribution fitting for building stochastic models

April 22, 2022

Author(s)

Siham Khoussi, N. Alan Heckert, Saddek Bensalem, Abdella Battou

Statistical model checking (SMC) is a formal verification method that combines simulations with statistical techniques to provide quantitative answers on whether a stochastic system satisfies some requirements with a controllable accuracy. SMC takes three

A Roadmap for LIMS at NIST Material Measurement Laboratory

Plant, Bruce D. Ravel, David J. Ross, John Henry J. Scott, Christopher Szakal, Alessandro Tona, Peter Vallone

Instrumentation generates data faster and in higher quantity than ever before, and interlaboratory research is in historic demand domestically and internationally to stimulate economic innovation. Strategic mission needs of the NIST Material Measurement

Blockchain and Related Technologies to Support Manufacturing Supply Chain Traceability

April 7, 2022

Author(s)

Keith A. Stouffer, Joshua Lubell, Michael Pease, Evan K. Wallace

As supply chains become more complex and the origins of products become harder to discern, efforts are emerging that improve traceability of goods by exchanging traceability data records using blockchain and related technologies. This NIST NCCoE

Guide to Enterprise Patch Management Planning: Preventive Maintenance for Technology

April 6, 2022

Author(s)

Murugiah Souppaya, Karen Scarfone

Enterprise patch management is the process of identifying, prioritizing, acquiring, installing, and verifying the installation of patches, updates, and upgrades throughout an organization. Patching is more important than ever because of the increasing

Improving Enterprise Patching for General IT Systems: Utilizing Existing Tools and Performing Processes in Better Ways

April 6, 2022

Author(s)

Murugiah Souppaya, Alper Kerman, Karen Scarfone, Kevin Stine, Brian E. Johnson, Chris Peloquin, Vanessa Ruffin, Tyler Diamond, Mark Simos, Sean Sweeney

Despite widespread recognition that patching is effective and attackers regularly exploit unpatched software, many organizations do not adequately patch. There are myriad reasons why, not the least of which are that it's resource-intensive and that the act

Augmented Reality (AR) Usability Evaluation Framework: The Case of Public Safety Communications Research

April 5, 2022

Author(s)

Yee-Yin Choong, Kurtis Goad, Kevin C. Mangold

Augmented Reality (AR) is an enhanced version of reality created by the use of technology to overlay digital information on an image of something being viewed through a device. AR has potential uses in many fields such as education, retail, repair

Combination Frequency Differencing for Identifying Design Weaknesses in Physical Unclonable Functions
