Insights
WISeKey's planned
The mission mounts SEALSQ post‑quantum semiconductors and WISeKey's Root of Trust on a WISeSat nanosatellite to validate end‑to‑end quantum‑resilient links between space, ground stations, and IoT devices. Real‑time in‑orbit testing under space conditions provides direct operational evidence about the hardware and protocol behaviour outside lab environments. This moves the technology from simulation to empirical validation, which matters for later certification and operational deployment.
Dependencies and risks include successful launch and on‑orbit commissioning, hardware survivability in radiation and thermal cycles, and reliable ground segment integration. Results are binary in value: either the chip and protocol operate as designed or they reveal issues requiring design changes. Watch for telemetry on on‑orbit key exchange success, error rates, and any reported firmware or integration faults during the days after
