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…
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…
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…
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…
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…
