FPGA-Based Lightweight Hardware Architecture of the PHOTON Hash Function for IoT Edge Devices

IEEE Access, 2020
The design of cryptographic engines for the Internet of Things (IoT) edge devices and other ultralightweight devices is a crucial challenge. The emergence of such resource-constrained devices raises significant challenges to current cryptographic ...

Voxel‐SLAM: A Complete, Accurate, and Versatile Light Detection and Ranging‐Inertial Simultaneous Localization and Mapping System

Advanced Intelligent Systems, EarlyView.
: In this work, Voxel‐SLAM (simultaneous localization and mapping) is introduced: a complete, accurate, and versatile LiDAR (light detection and ranging) ‐inertial SLAM system consisting of five modules: initialization, odometry, local mapping (LM), loop closure (LC), and global mapping (GM), all employing the same map representation, an adaptive voxel

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59

Astronomische Nachrichten, EarlyView.
ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

Preimage and pseudo-collision attacks on 29-step SM3 hash function with padding

Tongxin xuebao, 2014
The security of SM3 hash function was revaluated by using the meet-in-the-middle attack. The preimage and pseudo-collision attack on 29-step SM3 hash function (from the 1-st step) with padding was presented.

XML data integrity based on concatenated hash function [PDF]

, 2009
Data integrity is the fundamental for data authentication. A major problem for XML data authentication is that signed XML data can be copied to another document but still keep signature valid. This is caused by XML data integrity protecting.

Hyperledger Fabric for the (digitalized) lifecycle of construction products: Applied review on fastening technology

Civil Engineering Design, Volume 7, Issue 1, Page 9-22, March 2025.
Abstract Blockchain technology is a digital decentralized data ledger recording transactions in an encrypted format. Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized

Hash function requirements for Schnorr signatures

Journal of Mathematical Cryptology, 2009
We provide two necessary conditions on hash functions for the Schnorr signature scheme to be secure, assuming compact group representations such as those which occur in elliptic curve groups. We also show, via an argument in the generic group model, that

Simple Access to a Series of Higher Substituted Pentafluoroorthotellurate‐Based Silanes

Chemistry – A European Journal, EarlyView.
The pentafluoroorthotellurate ligand was introduced to organo silanes. A variety of silanes with the formular RxSi(OTeF5)4–x were synthesized and characterized via spectroscopic techniques and sc‐XRD. The influence of the number of OTeF5 groups on structural properties as well as the fluoride ion affinities (FIA) has been studied and compared to other ...

Development of a New Post-Quantum Digital Signature Algorithm: Syrga-1

Computers
The distinguishing feature of hash-based algorithms is their high confidence in security. When designing electronic signature schemes, proofs of security reduction to certain properties of cryptographic hash functions are used.
