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...

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...
