Selection Integrity for LLM Graph Memory: An Accumulability Criterion for Information-Flow-Blind Retrieval
Zeming Fei, Hongming Fei, Xiaoyang Wang +4
Agent memory is moving to graphs, and the provenance defenses now being built for it all check one thing: the provenance of the records an agent retrieves. We show that this entire…
Broadband source-surrounded cloak for on-chip antenna radiation pattern protection
Hanchuan Chen, Fei Sun, Yichao Liu +3
As the frequency range of electromagnetic wave communication continues to expand and the integration of integrated circuits increases, electromagnetic waves emitted by on-chip ante…
On-chip ultra-compact hexagonal boron nitride topological ring-resonator in visible region
Min Wu, Yibiao Yang, Hongming Fei +3
Ultra-compact topological ring-resonators with chirality are important devices for quantum optics. However, there are limited demonstrations of chiral resonators, especially in the…
Attacking Delay-based PUFs with Minimal Adversary Model
Hongming Fei, Owen Millwood, Prosanta Gope +2
Physically Unclonable Functions (PUFs) provide a streamlined solution for lightweight device authentication. Delay-based Arbiter PUFs, with their ease of implementation and vast ch…
Quantifying Memory Cells Vulnerability for DRAM Security
Zilong Hu, Hongming Fei, Prosanta Gope +3
Dynamic Random Access Memory (DRAM) is pervasive in computer systems. Cell vulnerabilities caused by unintended phenomena (forced retention failure, latency alteration, rowhammer a…
A nanophotonic all-optical diode for non-reciprocal transmission of circularly polarized lights
Hongming Fei, Min Wu, Han Lin +4
All optical diodes (AODs) play an important role in quantum optics and information processing, in which the information is encoded by photons. Only circularly polarized lights are…
Unified Framework for Qualifying Security Boundary of PUFs Against Machine Learning Attacks
Hongming Fei, Zilong Hu, Prosanta Gope +1
Physical Unclonable Functions (PUFs) serve as lightweight, hardware-intrinsic entropy sources widely deployed in IoT security applications. However, delay-based PUFs are vulnerable…
High-performance chiral all-optical logic gate based on topological edge states of valley photonic crystal
Xiaorong Wang, Hongming Fei, Han Lin +6
For all-optical communication and information processing, it is necessary to develop all-optical logic gates based on photonic structures that can directly perform logic operations…
PhenoAuth: A Novel PUF-Phenotype-based Authentication Protocol for IoT Devices
Hongming Fei, Owen Millwood, Gope Prosanta +2
Physical Unclonable Functions (PUFs) have been shown to be a highly promising solution for enabling high security systems tailored for low-power devices. Commonly, PUFs are utilise…
