Asymptotic Analysis of Plausible Tree Hash Modes for SHA-3 [PDF]

, 2017
Discussions about the choice of a tree hash mode of operation for a standardization have recently been undertaken. It appears that a single tree mode cannot address adequately all possible uses and specifications of a system. In this paper, we review the

LRPS‐GCN: A millimeter wave sparse imaging algorithm based on graph signal

IET Radar, Sonar &Navigation, Volume 18, Issue 10, Page 1652-1669, October 2024.
To address the slow speed and poor accuracy issues of traditional millimeter wave sparse imaging, a novel sparse imaging algorithm based on graph convolution model is introduced, utilising low‐rank and piecewise smoothing regular terms to construct the graph signal model and employing a denoising graph convolution network for sparse reconstruction ...

Whirlwind: a new cryptographic hash function [PDF]

, 2010
A new cryptographic hash function Whirlwind is presented. We give the full specification and explain the design rationale. We show how the hash function can be implemented efficiently in software and give first performance numbers. A detailed analysis of

The role of viruses in oral mucosal lesions

Periodontology 2000, Volume 96, Issue 1, Page 189-202, October 2024.
Abstract The mucosa of the oral cavity is exposed to a large number of different microorganisms such as archaea, bacteria, fungi, parasites, and viruses. Among those, viruses cause specific infections, which can easily be transmitted from one person to another.

Quantum authentication with key recycling [PDF]

, 2017
We show that a family of quantum authentication protocols introduced in [Barnum et al., FOCS 2002] can be used to construct a secure quantum channel and additionally recycle all of the secret key if the message is successfully authenticated, and recycle ...

Indifferentiable Hashing to Barreto–Naehrig Curves [PDF]

, 2012
A number of recent works have considered the problem of constructing constant-time hash functions to various families of elliptic curves over finite fields. In the relevant literature, it has been occasionally asserted that constant-time hashing to certain special elliptic curves, in particular so-called BN elliptic curves, was an open problem.

An innovative way to use 3D modeling on burnt bone to differentiate heat fractures from blunt and sharp force trauma

WIREs Forensic Science, Volume 6, Issue 5, September/October 2024.
(a) Blunt force injury to calotte in fresh bone, fractures indicated by black arrows, (b) same calotte after partial cremation, black arrows indicate the same blunt force fractures, the red arrow indicates the fracture showed in (c) and (d), (c) this is the depth analysis produced by the Keyence VHX‐2000 of the fracture pointed to by the red arrow in ...

MiMC:Efficient Encryption and Cryptographic Hashing with Minimal Multiplicative Complexity [PDF]

, 2016
We explore cryptographic primitives with low multiplicative complexity. This is motivated by recent progress in practical applications of secure multi-party computation (MPC), fully homomorphic encryption (FHE), and zero-knowledge proofs (ZK) where ...

Constraining Mean Landslide Occurrence Rates for Non‐Temporal Landslide Inventories Using High‐Resolution Elevation Data

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 8, August 2024.
Abstract Constraining landslide occurrence rates can help to generate landslide hazard models that predict the spatial and temporal occurrence of landslides. However, most landslide inventories do not include any temporal data due to the difficulties of dating landslide deposits.

Lattice Boltzmann Method for mixtures at variable Schmidt number

, 2014
When simulating multicomponent mixtures via the Lattice Boltzmann Method, it is desirable to control the mutual diffusivity between species while maintaining the viscosity of the solution fixed.
