Physical Unclonable Functions From Microwave Metasurface Fingerprints

Advanced Electronic Materials, EarlyView.
Nominally identical metasurfaces fabricated through standard PCB processes inevitably contain microscopic fabrication imperfections. This work demonstrates that these unavoidable electromagnetic deviations can serve as unique physical unclonable fingerprints for wireless authentication.

Cryptographic Energy Costs are Assumable in Ad Hoc Networks [PDF]

, 2009
Performance of symmetric and asymmetric cryptography algorithms in small devices is presented. Both temporal and energy costs are measured and compared with the basic functional costs of a device. We demonstrate that cryptographic power costs are not

Variable Bit Permutations: Linear Characteristics and Pure VBP-Based Cipher [PDF]

Computer Science Journal of Moldova, 2005
This paper describes linear characteristics of the variable bit permutations (VBP) that are used in the form of the data-dependent permutations. This primitive suites well to the design of fast cheap-hardware-oriented ciphers. Because of the existence of

Quasi‐2D perovskite memristors: From layered structures to advanced computing applications

InfoScience, EarlyView.
Quasi‐2D perovskites enable stable memristive switching through dimensional engineering that controls ion migration pathways. The layered structure suppresses leakage, improves environmental stability, and enables analog conductance modulation for neuromorphic computing, artificial vision, and in‐memory architectures, transforming ion migration from a ...

Toward Encrypted OPF Across Transmission and Distribution—Prospects and Open Problems of Encrypted Quadratic Programming

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The increasing integration of distributed energy resources demands enhanced coordination between transmission system operators (TSOs) and distribution system operators (DSOs) to maintain reliable grid operation. Traditional approaches rely on hierarchical or distributed optimization schemes for power flow management, but these methods either ...

Secure Single-Server Aggregation with (Poly)Logarithmic Overhead

IACR Cryptology ePrint Archive, 2020
Secure aggregation is a cryptographic primitive that enables a server to learn the sum of the vector inputs of many clients. Bonawitz et al. (CCS 2017) presented a construction that incurs computation and communication for each client linear in the ...

Crystallization‐Driven Helical Conjugated Polymer Nanowires for Circularly Polarized Light‐Addressable Ferroelectric Physical Unclonable Functions

Small, EarlyView.
Supramolecular helicity meets ferroelectricity: P3HT‐b‐PMMA helical nanowires enable handedness‐specific modulation of remanent polarization in P(VDF‐TrFE) hybrids. This platform demonstrates the first CPL‐addressable ferroelectric PUF, translating molecular chirality into secure digital authentication.
