Ag/Ag2S Nanoparticle‐Based In‐Materio Lightweight Cryptographic System for IoT Edge Security

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 8, August 2026.
This work presents a nanomaterial‐based in materio encryption method that directly transforms analog signals through nonlinear Ag/Ag2S nanoparticle networks. By exploiting the inherently nonuniform characteristics that arise from random arrangement of nanoparticles as a unique security key, the approach produces highly complex encrypted waveforms ...

Improvement and Cryptanalysis of a Physically Unclonable Functions Based Authentication Scheme for Smart Grids

open access: yesMathematics, 2022
Authentication protocols are often used in smart grids to deliver the necessary level of security. A huge number of clients in such a system, however, provides the attacker with the ability to clone them, for example.

Designing chiral organic small molecules for circularly polarized light detection via group theory

open access: yesInfoMat, Volume 8, Issue 8, August 2026.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...
