Vertical coordination in agri‐food supply chain and blockchain: A proposed framework solution for Vietnamese cashew nut business

open access: yesRegional Science Policy &Practice, EarlyView., 2022
Abstract The agri‐food supply chain has been a popular research topic in recent years. The combination of a demand for products of high quality and safety standards and the increasing number of stakeholders in supply chain networks has required the agri‐food business to transform from vertically integrated to vertically operated supply chain networks ...

Cryptanalysis of The Hwang-Shi Proxy Signature Scheme

open access: yes, 2012
[[abstract]]Recently, Hwang and Shi proposed an efficient proxy signature scheme without using one-way hash functions. In their scheme, an original signer needn't send a proxy certificate to a proxy signer through secure channels.

Collision Resistance of the JH Hash Function [PDF]

open access: yes, 2011
In this paper, we analyze collision resistance of the JH hash function in the ideal primitive model. The JH hash function is one of the five SHA-3 candidates accepted for the final round of evaluation.

Migration, Repression and Homosexual Sociability in Francoist Spain: An Analysis of the Case Files of the Special Courts of Barcelona (1965–1975)

open access: yesGender &History, EarlyView.
ABSTRACT In Spain, under General Franco's regime, homosexuality was regarded as an antisocial and dangerous behaviour. It was thus pursued both by the police and judicial courts. The Law on Vagrants and Crooks (1954) and, subsequently, the Law on Dangerousness and Social Rehabilitation (1970) constituted the legal mechanisms used by the dictatorship to

Collision Attack on the Waterfall Hash Function [PDF]

open access: yes, 2008
We give a method that appears to be able to find colliding messages for the Waterfall hash function with approximately $O(2^{70})$ work for all hash sizes. If correct, this would show that the Waterfall hash function does not meet the required collision

The effect of nearby listings on house sale prices in Sydney: A spatio‐temporal regularization approach

open access: yesReal Estate Economics, EarlyView.
Abstract We estimate the price impact of very nearby concurrently listed properties in the Sydney housing market and assess their competition effects. We apply a hedonic model with spatiotemporal effects regularized via a graph Laplacian prior at the month‐by‐SA2 regional level to seven SA4 subregions of metropolitan Sydney. The model structure enables

Preserving evidence integrity in full file system extractions: Assessing hash inconsistencies and potential solutions

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Smartphone manufacturers' enhanced privacy and security measures, such as File‐Based Encryption (FBE), have disrupted traditional data extraction techniques, necessitating the adoption of Full File System Extraction (FFS). FFS requires booting a smartphone, decrypting its UserData partition, and accessing files individually, a process that ...

The hash function fugue

open access: yes, 2008
We describe Fugue, a hash function supporting inputs of length upto 264 − 1 bits and hash outputs of length upto 512 bits. Notably, Fugue is not based on a compression function. Rather, it is directly a hash function that supports variable-length inputs.
