Voyager Space and IBM Successfully Test Post-Quantum Security on ISS Communication Link
By
Mohamed Abdel-Kareem
Summary
Voyager Space and IBM have successfully demonstrated a post-quantum secured communication link between Earth and the International Space Station (ISS). The demonstration used Voyager's Space Edge Micro Datacenter (launched to the ISS in September 2025) combined with IBM's Quantum Safe Remediator software. This orbital milestone proves that satellite data can be protected against future quantum computing threats, marking a significant step forward in space-based cybersecurity.
