Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Uniform Sharing in Multiple Stages: NullFresh for Arbitrary Functions

Transactions on Cryptographic Hardware and Embedded Systems
In the field of hardware masking, threshold implementations are a wellknown technique that provides glitch-resistant power analysis security. While they guarantee probing security, finding a uniform sharing without additional randomness is difficult ...

Speculative Probing: Hacking Blind in the Spectre Era

Conference on Computer and Communications Security, 2020
To defeat ASLR or more advanced fine-grained and leakage-resistant code randomization schemes, modern software exploits rely on information disclosure to locate gadgets inside the victim's code. In the absence of such info-leak vulnerabilities, attackers

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

A Deep Analysis of two Glitch-Free Hardware Masking Schemes SESYM and LMDPL

Transactions on Cryptographic Hardware and Embedded Systems
In the context of masking, which is the dominant technique for protecting cryptographic hardware designs against Side-Channel Analysis (SCA) attacks, the focus has long been on the design of masking schemes that guarantee provable security in the ...

Algorithmic Tamper-Proof Security under Probing Attacks [PDF]

, 2010
Gennaro et al. initiated the study of algorithmic tamper proof (ATP) cryptography: cryptographic hardware that remains secure even in the presence of an adversary who can tamper with the memory content of a hardware device. In this paper, we solve an open problem stated in their paper, and also consider whether a device can be secured against an ...

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed
