Measurement applications for our contribution: A Performance Study of Crypto-Hardware in the Low-end IoT

A playground for post-quantum cryptography (PQC) on embedded systems and edge devices

Curve25519-powered Zephyr supervisor for STM32L0: derives AES keys per boot, encrypts reset/watchdog state, enforces dual-heartbeat SLAs, and orchestrates safe-mode recovery after power dips. Ships with native_sim + hardware tests, release logs, security backlog, and GitHub Actions CI so 8 KB Cortex‑M0 nodes can reboot with audit-ready telemetry.

Secure Boot & Firmware Integrity implementation for STM32F4

Implementation of a secure, low-level application designed on CertiKOS formally verified operating system kernel. Simulation of an autonomous satellite critical susystems - environmental monitoring, task scheduling and watchdog diagnostics - within a trusted computing environment. Developed as part of my diploma thesis at the University of Patras.
