We demonstrate a post-quantum key-exchange with the nanosatellite SpooQy-1 in
low Earth orbit using Kyber-512, a lattice-based key-encapsulation mechanism
and a round three finalist in the NIST PQC standardization process. Our
firmware solution runs on an on-board computer that is based on the Atmel AVR32
RISC microcontroller, a widely used platform for nanosatellites. We uploaded
the new firmware with a 436.2 MHz UHF link using the CubeSat Space Protocol
(CSP) and performed the steps of the key exchange in several …
