Partner Presentations are 60 minute presentations and/or discussions from our exhibitors and sponsors, located in the Lovelace Room (near entrance).
PRESENTED BY: wolfSSL Inc
T.J. Fure (Vorago VP Sales) introduces Vorago’s radiation-hardened Cortex-M4 with Triple-Mode Redundancy (TMR), designed for space and defense applications. The VA416xx features a unique architecture using FRAM instead of traditional Flash memory, with Shadow IRAM execution for enhanced reliability. He explains why secure boot is critical for mission-critical systems where failures aren’t an option.
David Garske (Software Engineer wolfSSL) demonstrates wolfBoot live on the VA416xx hardware, showing cryptographic signature verification protecting against unauthorized firmware. He performs a secure firmware update with version control and rollback protection, highlighting how FRAM’s instant writes and unlimited endurance make it ideal for bootloaders. The audience sees real-time UART output showing the boot process, update mechanism, and safety features.
Key takeaways: Space-grade security without complexity, 19-38KB code size depending on algorithm, sub-500ms updates including verification, and production-ready cryptography suitable for DO-178C certification paths.
