Femtosecond‐Laser‐Induced Physical Unclonable Random Maze Structure for Storage‐Free Encryption

Advanced Science, Volume 13, Issue 49, 3 September 2026.
Femtosecond‐laser‐induced gold random maze structures serve as multimodal physical unclonable functions for storage‐free encryption. Their stochastic optical, electrical, and Raman responses are generated by plasmon‐assisted Marangoni formation and converted into AES‐compatible keys without permanent secret‐key storage, offering a portable route toward

A Secure and Robust Image Hashing Scheme Using Gaussian Pyramids

Entropy, 2019
Image hash is an alternative to cryptographic hash functions for checking integrity of digital images. Compared to cryptographic hash functions, an image hash or a Perceptual Hash Function (PHF) is resilient to content preserving distortions and ...

Compositional Security for Blockchain‐Based Agentic Commerce: Cross‐Layer Binding, Predicate‐Constrained Settlement, and Evidence‐Linked Verification in AI‐Agent Payments

Engineering Reports, Volume 8, Issue 9, September 2026.
This paper presents CLB‐ACEL, a cross‐layer binding and evidence verification framework for agentic blockchain payments. Across ten human‐present attacks and five delegated predicate scenarios, CLB‐ACEL detects every modeled unsafe case and prevents replay plus all predicate violations at or before settlement. ABSTRACT Autonomous AI agents increasingly

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

, 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 ...

Superior Cardiorenal Protection With Tirzepatide Over Dulaglutide in Heart Failure With Preserved Ejection Fraction: A Large‐Scale Propensity Score–Matched Real‐World Analysis

Clinical Cardiology, Volume 49, Issue 8, August 2026.
In this large real‐world propensity‐matched analysis, tirzepatide demonstrated superior reductions in mortality, hospitalizations, and cardiorenal outcomes versus dulaglutide in HFpEF patients, with a favorable safety profile. ABSTRACT Background No direct head‐to‐head trials compare tirzepatide and dulaglutide in heart failure with preserved ejection ...

Black-Box Property of Cryptographic Hash Functions [PDF]

, 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

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

Concurrency 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 ...
