OSS + ELC EU 2026

Global regulatory shifts—driven by strict NDAA requirements and EASA U-Space mandates—require drone manufacturers to implement verifiable supply chain security. Software-only implementations of FAA Remote ID remain vulnerable to key spoofing and firmware tampering. This session delivers a practical breakdown of how to enforce a hardware root of trust by embedding physical Secure Elements (like the OPTIGA Trust M) into open flight controllers running PX4 and NuttX.
We will bypass high-level concepts to dive straight into the embedded architecture:
Configuring the SPI/I2C bus interface between the flight MCU (PSoC C3M) and the security peripheral.
Modifying the NuttX driver layer to offload ECDSA signing keys for broadcast messages without blocking safety-critical flight loop threads.
Structuring secure boot sequences to protect downstream firmware from local physical exploits.
We will share timing benchmarks showing how to manage cryptographic latency within standard PX4 task frequencies to build compliant systems without sacrificing real-time flight performance.
