Published purpose

(20STDPL16) To prevent cyberattack, satellite communications are often encrypted using encryption keys loaded onto the satellite before launch. Should keys be compromised, it is impossible to load new keys onto a satellite in orbit. QEYnet is developing a solution to this issue using Quantum Key Distribution (QKD) technology, in which encryption keys are sent from the ground to the satellite as a stream of individual photons. By the laws of quantum mechanics, any attempt at eavesdropping on a QKD system can be detected, so the encryption keys produced are highly secure. However, deviations in real hardware from the theoretical ideal can result in unintended side-channels and vulnerabilities, exposing QKD to attack. This project will test a novel system of countermeasures addressing these vulnerabilities, enabling a rapid transition of the QKD technology toward commercial readiness. Robust satellite encryption benefits every Canadian.
