Integrated Quantum-Secured Cryptographic Memory in Customizable Single Nanodiamonds

As advanced physical cloning and cyber-extraction techniques proliferate, achieving absolute hardware-level information security has become a paramount global challenge. Conventional architectures systems are fundamentally vulnerable because deterministic memory and cryptographic hardware are...

TroPUF: Evaluating Hardware Trojan Insertion in Delay-Based Physical Unclonable Functions

Delay-based Physical Unclonable Functions PUFs are commonly used for device authentication and key generation due to the fact that they rely on manufacturing induced delay variations. However, these same variations make PUFs inherently non-deterministic, which can allow malicious logic to blend i...

CVE-2026-2815

The CVE affects Silicon Labs’ EFR32xG27 devices. Issue: Incorrect use of the PUF key for user key generation leads to predictable keys. This is tied to a CVSS 4.0 base score of 8.4 (HIGH) with adjacent access, low attack complexity, no authentication, and user interaction not required. The vulner...

CVE-2026-2815: Small Seed Space in PRNG

Incorrect use of the PUF key for user key generation in EFR32xG27 results in predictable keys...

Unified Framework for Qualifying Security Boundary of PUFs against Machine Learning Attacks

Physical Unclonable Functions PUFs serve as lightweight, hardware-intrinsic entropy sources widely deployed in IoT security applications. However, delay-based PUFs are vulnerable to Machine Learning Attacks MLAs, undermining their assumed unclonability. There are no valid metrics for evaluating P...

A TRNG Implemented Using a Soft-Data Based Sponge Function within a Unified Strong PUF Architecture

Hardware security primitives including True Random Number Generators TRNG and Physical Unclonable Functions PUFs are central components to establishing a root of trust in microelectronic systems. In this paper, we propose a unified PUF-TRNG architecture that leverages a combination of the static...
