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
