2F - A New Method for Constructing Efficient Multivariate Encryption Schemes

September 28, 2022
Author(s)
Daniel Smith-Tone
The Support Minors method of solving the MinRank problem has contributed to several new cryptanalyses of post-quantum cryptosystems including some of the most efficient multivariate cryptosystems. While there are a few viable multivariate schemes that are

Breaking Category Five SPHINCS+ with SHA-256

September 28, 2022
Author(s)
Ray Perlner, David Cooper, John M. Kelsey
SPHINCS+ is a stateless hash-based signature scheme and a finalist in the NIST PQC standardization process. Its security proof relies on the distinct-function multi-target second-preimage resistance (DM-SPR) of the underlying keyed hash function. The

Efficient inner-to-outer wall energy transfer in highly pure double-wall carbon nanotubes revealed by detailed spectroscopy

September 28, 2022
Author(s)
Maksiem Erkens, Dmitry Levshov, Wim Wenseleers, Han Li, Benjamin Flavel, Jeffrey Fagan, Valentin Popov, Marina Avramenko, salome forel, Emmanuel FLAHAUT, Sofie Cambre
The coaxial stacking of two SWCNTs into a double-wall carbon nanotube (DWCNT), forming a so-called one-dimensional van der Waals structure, leads to synergetic effects that dramatically affect the optical and electronic properties of both layers. In this

IPRainbow

September 28, 2022
Author(s)
Ryann Cartor, Max Cartor, Mark Lewis, Daniel Smith-Tone
The Rainbow signature scheme as proposed in [10] is the only multivariate scheme listed as a finalist in round 3 of the NIST post-quantum standardization process. A few recent attacks, including the intersection and rectangular MinRank attacks of [3] and

Influence of Inorganic Layer Thickness on Methylammonium Dynamics in Hybrid Perovskite Derivatives

September 27, 2022
Author(s)
Alexandra Koegel, Iain Oswald, Chuy Rivera, Samantha L. Miller, M. Fallon, Timothy R. Prisk, Craig Brown, James Neilson
The layered Ruddlesden-Popper derivatives of CH 3NH 3PbI 3 have recently emerged as high-performing materials for photovoltaics with improved stability. The inclusion of organic molecules within the inorganic framework provides additional dynamic degrees

Report from the NIST Workshop: Launch of the Rapid Microbial Testing Methods Consortium

September 27, 2022
Author(s)
Nancy Lin, Scott Jackson, Stephanie Servetas, Kirsten Parratt, Joy Dunkers, Tara Eskandari, Sheng Lin-Gibson
On September 17, 2020, NIST hosted a virtual workshop to launch the Rapid Microbial Testing Methods (RMTM) Consortium. The RMTM Consortium aims to address the need for measurements and standards to increase confidence in the use of rapid testing for

2021 Cybersecurity and Privacy Annual Report

September 26, 2022
Author(s)
Patrick D. O'Reilly, Kristina Rigopoulos, Greg Witte, Larry Feldman
During Fiscal Year 2021 (FY 2021) – from October 1, 2020, through September 30, 2021 – the NIST Information Technology Laboratory (ITL) Cybersecurity and Privacy Program successfully responded to numerous challenges and opportunities in security and

High-Throughput Nanopore Fabrication and Classification Using Xe-Ion Irradiation and Automated Pore-Edge Analysis

September 26, 2022
Author(s)
Michal Macha, Sanjin Marion, Mukesh Tripathi, Martina Lihter, Alex Smolyanitsky, Andras Kis, Aleksandra Radenovic
Large-area nanopore drilling is a major bottleneck in state-of-the-art nanoporous 2D membrane fabrication protocols. In addition, high-quality structural and statistical descriptions of as-fabricated porous membranes are key to predicting the corresponding

Tightly Confined Surface Acoustic Waves as Microwave-to-Optical Transduction Platforms in the Quantum Regime

September 26, 2022
Author(s)
Ryan DeCrescent, Zixuan Wang, Poolad Imany, Robert Boutelle, Corey McDonald, Travis Autry, John Teufel, Sae Woo Nam, Richard Mirin
Surface acoustic waves (SAWs) coupled to quantum dots (QDs), trapped atoms and ions, and point defects have been proposed as quantum transduction platforms, yet the requisite coupling rates and cavity lifetimes have not been experimentally established

Liquid-Phase Speed of Sound and Vapor-Phase Density of Difluoromethane

September 23, 2022
Author(s)
Aaron Rowane, Elizabeth Rasmussen, Mark O. McLinden
Difluoromethane (HFC-32, DFM), with a global warming potential (GWP) of 677, is of interest as a pure refrigerant and as a component in low-GWP refrigerant mixtures. Additionally, difluoromethane has recently been identified as a safe, liquefied-gas

Population data for 94 identity SNPs in four U.S. population groups

September 23, 2022
Author(s)
Kevin Kiesler, Lisa Borsuk, Becky Steffen, Katherine Gettings, Peter Vallone
The U.S. National Institute of Standards and Technology (NIST) sequenced 1036 human DNA samples from four United States population groups (African American, Asian, Hispanic, and Caucasian) using the ForenSeq DNA Signature Prep Kit with Primer Mix B (DPMB)

Provably efficient machine learning for quantum many-body problems

September 23, 2022
Author(s)
Hsin-Yuan Huang, Richard Kueng, Giacomo Torlai, Victor Albert, John Preskill
Classical machine learning (ML) provides a potentially powerful approach to solving challenging quantum many-body problems that arise in physics and chemistry, but the advantages of ML over more traditional classical methods have not been firmly
