A Hash of Hash Functions [PDF]
arXiv, 2003 In this paper, we present a general review of hash functions in a cryptographic sense. We give special emphasis on some particular topics such as cipher block chaining message authentication code (CBC MAC) and its variants. This paper also broadens the information given in some well known surveys, by including more details on block-cipher based hash ...

On the (Im)plausibility of Public-Key Quantum Money from Collision-Resistant Hash Functions [PDF]
arXiv, 2023 Public-key quantum money is a cryptographic proposal for using highly entangled quantum states as currency that is publicly verifiable yet resistant to counterfeiting due to the laws of physics. Despite significant interest, constructing provably-secure public-key quantum money schemes based on standard cryptographic assumptions has remained an elusive

Quantum hashing is maximally secure against classical leakage [PDF]
arXiv, 2017 Cryptographic hash functions are fundamental primitives widely used in practice. For such a function $f:\{0, 1\}^n\to\{0, 1\}^m$, it is nearly impossible for an adversary to produce the hash $f(x)$ without knowing the secret message $x\in\{0, 1\}^n$.

Asymmetric cryptography and practical security
Journal of Telecommunications and Information Technology, 2002 Since the appearance of public-key cryptography in Diffie-Hellman seminal paper, many schemes have been proposed, but many have been broken. Indeed, for many people, the simple fact that a cryptographic algorithm withstands cryptanalytic attacks for ...

Accounting &Finance, EarlyView.Abstract This study explores the practical impact of blockchain technology (BCT), which contrasts strongly with literature that has predominantly hypothesised BCT's potential to disrupt accounting practice. We interviewed 44 practitioners and academics with knowledge of BCT across 13 countries and industries.

How to Formalize Loop Iterations in Cryptographic Protocols Using ProVerif
IEEE AccessThe formal verification of cryptographic protocols has been extensively studied in recent years. To verify the cryptographic protocol security, formal verification tools consider protocol properties as interactive processes involving a cryptographic ...

Towards Automated Augmentation and Instrumentation of Legacy Cryptographic Executables: Extended Version [PDF]
arXiv, 2020 Implementation flaws in cryptographic libraries, design flaws in underlying cryptographic primitives, and weaknesses in protocols using both, can all lead to exploitable vulnerabilities in software. Manually fixing such issues is challenging and resource consuming, especially when maintaining legacy software that contains broken or outdated ...

British Journal of Clinical Pharmacology, EarlyView.Aims The COVID‐19 pandemic created unprecedented pressure on healthcare services. This study investigates whether disease‐modifying antirheumatic drug (DMARD) safety monitoring was affected during the COVID‐19 pandemic. Methods A population‐based cohort study was conducted using the OpenSAFELY platform to access electronic health record data from 24.2 ...
