HFERP -- A New Multivariate Encryption Scheme

April 1, 2018
Author(s)
Yashuhiko Ikematsu, Ray Perlner, Daniel Smith-Tone, Tsuyoshi Takagi, Jeremy Vates
In 2016, Yasuda et al.presented a new multivariate encryption technique based on the Square and Rainbow primitives and utilizing the plus modifier that they called SRP. The scheme achieved a smaller blow-up factor between the plaintext space and ciphertext

Improved Cryptanalysis of HFEv- via Projection

April 1, 2018
Author(s)
Jintai Ding, Ray Perlner, Albrecht R. Petzoldt, Daniel Smith-Tone
The HFEv- signature scheme is one of the most studied multivariate schemes and one of the major candidates for the upcoming standardization of post-quantum digital signature schemes. In this paper, we propose three new attack strategies against HFEv-, each

Journal of Applied Crystallography: The First 50 Years and Beyond

April 1, 2018
Author(s)
Andrew Allen, Janos Hajdu, Garry J. McIntyre
The first issue of the Journal of Applied Crystallography appeared in April 1968. So, with this issue we celebrate its 50th birthday! We should start by expressing our appreciation for all the readers, authors, reviewers, editors and technical staff who

Nonuniform Sampling in Multidimensional NMR for Improving Spectral Sensitivity

April 1, 2018
Author(s)
Matthew Zambrello, Adam D. Schuyler, Mark W. Maciejewski, Frank Delaglio, Irina Bezsonova, Jeffrey C. Hoch
The development of multidimensional NMR spectroscopy enabled an explosion of structural and dynamical investigations on proteins and other biomacromolecules. Practical limitations on data sampling, based on the Jeener paradigm of parametric sampling of

The development of multidimensional NMR spectroscopy enabled an explosion of structural and dynamical investigations on proteins and other biomacromolecules. Practical limitations on data sampling, based on the Jeener paradigm of parametric sampling of

Perfluorinated Alkyl Acids and Fecundity Assessment in Striped mullet (Mugil cephalus) at Merritt Island National Wildlife Refuge

April 1, 2018
Author(s)
John Bowden, Jacqueline T. Bangma, Jessica L. Reiner, Russell H. Lowers, Theresa M. Cantu, Jacob Scott, Jeffery Korte, Douglas M. Scheidt, Chris McDonough, Jonathan Tucker, Eric Reyier, Douglas H. Adams, Bonnie Ahr, Brenton Back
This study investigated wild caught Striped mullet (Mugil cephalus) at Merritt Island National Wildlife Refuge (MINWR) for levels of 15 perfluoroalkyl acids (PFAAs) in tandem with fecundity measurements (n = 42) and oocyte developmental stages (n = 128)

Simultaneous Neutron and X-Ray Imaging of 3D Structure of Organic Matter and Fracture in Shales

April 1, 2018
Author(s)
Wei-Shan NMN Chiang, Jacob M LaManna, Daniel S. Hussey, David L. Jacobson, Yun Liu, Jilin Zhang, Daniel T. Georgi, Jordan R. Kone, Jin-hong Chen
Hydrocarbon production from shales using horizontal drilling and hydraulic fracturing has been the key development in the US energy industry in the past decade and has now become more important globally. Nevertheless, many fundamental problems related to

Stress Profiling in Cold-Spray Coatings by Different Experimental Techniques: Neutron Diffraction, X-ray Diffraction and Slitting Method

April 1, 2018
Author(s)
Vladimir Luzin, Kevin Spencer, Michael R. Hill, Tao Wei, Michael Law, Thomas H. Gnaupel-Herold
The residual stress profiles in Cu and Al coatings sprayed using kinetic metallization to thickness of 2 mm have been studied. Due to specific parameters of the cold spray process and particular combination of materials of coatings and substrates the

A Survey of Physics-Based Attack Detection in Cyber-Physical Systems

March 30, 2018
Author(s)
Jairo Giraldo, David Urbina, Alvaro Cardenas, Junia Valente, Mustafa Faisal, Justin Ruths, Niles O. Tippenhauer, Heinrik Sandberg, Rick Candell
Monitoring the "physics" of cyber-physical systems to detect attacks is a growing area of research. In its basic form a security monitor creates time-series models of sensor readings for an industrial control system and identifies anomalies in these
