The first open source software-based Physically Unclonable Function (PUF) using off-the-shelf SRAM

Hardware-based authentication using SRAM Physical Unclonable Functions (PUF) on ESP32 microcontrollers. Research-based PoC with 44,778 measurements across 16 devices over 6 months.

Open-platform for the acquisition of SRAM-based PUFs from Micro-Controllers

Measurement applications for our contribution: PUF for the Commons: Enhancing Embedded Security on the OS Level

🔒 Authenticate devices using ESP32 SRAM PUFs, leveraging unique hardware fingerprints to generate secure tokens without storing credentials.
