Cryptographic Hash Functions [PDF]

open access: yes, 2009
Kryptografiske hashfunktioner anvendes i mange forskellige områder inden for kryptografi: i digitale signatursystemer og i såkaldt public‐key kryptografi, til passwordbeskyttelse og autentificering af beskeder, til dannelse af kryptografiske nøgler og ...

Characterizing Open Addressing Hash Functions [PDF]

open access: yes, 2020
In [1], we showed that different open addressing hash functions perform differently when the data elements are not uniformly distributed. So, it is tempting to attribute their difference to some mechanism governing the behavior of the hash functions.

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

open access: yesThe Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Secure Parallel Image Cryptographic Hash Function Using a Novel 2D High-Randomness Hyperchaotic Map

open access: yesMathematics
For image data, the processing of each pixel using a cryptographic hash function is linear, and the existing cryptographic hash function lacks parallel processing of image width and height.

The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

open access: yesPolymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Integrated-key cryptographic hash functions [PDF]

open access: yes, 2011
Cryptographic hash functions have always played a major role in most cryptographic applications. Traditionally, hash functions were designed in the keyless setting, where a hash function accepts a variable-length message and returns a fixed-length ...

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Design of a Cellular Automata-Based Permutation Network for Cryptographic Hash Functions

open access: yesApplied Sciences
Cryptographic hash functions rely on efficient internal permutation mechanisms to achieve the diffusion and nonlinear transformations required for secure data integrity verification. This paper presents the design of a Cellular Automata-Based Permutation
