A Novel Improvement With an Effective Expansion to Enhance the MD5 Hash Function for Verification of a Secure E-Document

open access: yesIEEE Access, 2020
MD5 is a one-way cryptographic function used in various fields for maintaining data integrity. The application of a Hash function can provide much protection and privacy and subsequently reduce data usage.

MusicoCrypt: A Music‐Modulated Stream Cipher Using Deep Pitch Estimation and Number‐Theoretic Dynamics

open access: yesConcurrency and Computation: Practice and Experience, Volume 38, Issue 15, August 2026.
ABSTRACT This paper presents MusicoCrypt, a context‐bound music‐modulated stream‐encryption framework that incorporates audio‐derived public side information into a pseudorandom‐function‐centered encryption workflow. A shared reference recording is processed using a pitch‐tracking pipeline, and ordered note pairs are encoded as residues in ℤ132 ...

Automated Differentiation of Oral Red‐White Lesions: An Interpretable Deep Learning Approach Combining Ensemble Architectures and Saliency Maps

open access: yesClinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Introduction Oral Potentially Malignant Disorders (OPMDs), including Leukoplakia and Erythroplakia, carry significant risks of malignant transformation. Early differentiation from confounding inflammatory conditions like Oral Lichen Planus (OLP) and Candidiasis is critical yet challenging due to visual similarities.

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 8, August 2026.
Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies

open access: yesInternational Economic Review, Volume 67, Issue 3, Page 957-976, August 2026.
ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

Black-Box Property of Cryptographic Hash Functions [PDF]

open access: yes, 2012
We define a new black-box property of cryptographic hash function families H :{0,1}K ×{0,1}*→{0,1}y which guarantees that for a randomly chosen hash function H K from the family, everything "non-trivial" we are able to compute having access to the key K , we can compute only with oracle access to H K . If a hash function family is pseudo-random and has

On the Design of Provably-Secure Cryptographic Hash Functions [PDF]

open access: yes, 1991
Recently, formal complexity-theoretic treatment of cryptographic hash functions was suggested. Two primitives of Collision-free hash functions and Universal one-way hash function families have been defined. The primitives have numerous applications in secure information compression, since their security implies that finding collisions is ...

The Other Side of the Stethoscope: Clinician‐Facing Deepfakes and the Symmetry of Synthetic Deception

open access: yesJournal of Evaluation in Clinical Practice, Volume 32, Issue 5, August 2026.
ABSTRACT Background Clinical ethics scholarship on deepfakes has focused primarily on patients as targets of synthetic deception, in which fabricated audiovisual material alters patient beliefs about clinicians and care. This focus neglects the reverse epistemic vulnerability: clinicians themselves as recipients of synthetic, adversarially generated ...
