Deck-Based Wide Block Cipher Modes and an Exposition of the Blinded Keyed Hashing Model

IACR Transactions on Symmetric Cryptology, 2020
We present two tweakable wide block cipher modes from doubly-extendable cryptographic keyed (deck) functions and a keyed hash function: double-decker and docked-double-decker.

A Symbolic Intruder Model for Hash-Collision Attacks [PDF]

, 2006
In the recent years, several practical methods have been published to compute collisions on some commonly used hash functions. In this paper we present a method to take into account, at the symbolic level, that an intruder actively attacking a protocol ...

A Cryptographic Hash Function from Markoff Triples

, 2021
Cryptographic hash functions from expander graphs were proposed by Charles, Goren, and Lauter in [CGL] based on the hardness of finding paths in the graph. In this paper, we propose a new candidate for a hash function based on the hardness of finding paths in the graph of Markoff triples modulo p.

Institutional Environment and the Use of Blockchain Technology: Exploring the Context and Conditions of Using Blockchain in the Higher Education Institutions

Higher Education Quarterly, Volume 79, Issue 3, July 2025.
ABSTRACT Blockchain (BC) technology is widely believed to be the next disruptive technology that can address challenges in higher education institutions (HEIs) and support resilient strategies. This study aims to contribute to the literature and inform policymakers about BC's capability and potential in HE by examining enablers, barriers and contextual

Blockchain Systems in Food Supply Chains: An Interpretation Through the Lens of Agency and Technology–Organization–Environment Theories

Journal of Business Logistics, Volume 46, Issue 3, July 2025.
ABSTRACT Blockchain (BC) systems are increasingly used by consortia to monitor ex‐post opportunism in food supply chains. BC systems differ for BC technical characteristics, complementary technologies, and organizational tools. Yet, little is empirically known about the link between different BC system designs and the context where they are implemented

A new design paradigm for provably secure keyless hash function with subsets and two variables polynomial function

Journal of King Saud University: Computer and Information Sciences, 2022
Provably secure keyless hash function uses Random Oracle (RO) or Sponge principles for the design and construction of security-centric hash algorithms. It capitalizes the aforesaid principles to produce outcomes like MD2, MD5, SHA-160, SHA-224/256, SHA ...
