Post-Quantum Satellite Protection Rockets Towards Reality

A successful multi-orbit cryptography test beamed quantum-agile data up to two different satellites and back down to Earth.

Developers of post-quantum cryptography have successfully created a trial, data-transmission channel from Earth to satellites in multiple orbits that would be resistant to the hacking of the future.
The idea is to protect data routed via satellite clusters from being harvested and decrypted by quantum computers and to protect the operational technology communications that keep the arrays functioning. The challenge lies in maintaining resource-intensive, post-quantum protection along multiple hops as a signal is beamed around a cluster, with a data transmission rate thats acceptable for military and commercial real-time communications (and other applications).
During the test, carried out by QuSecure and Accenture, a data-transmission channel protected by both classical RSA-2048 and
post-quantum encryption
was opened to a low-Earth orbit (LEO) satellite and switched to a higher-altitude geosynchronous orbit (GEO) satellite, and then beamed back down to Earth.
As more organizations are increasingly relying on space technology to provide solutions, resiliency, and more relevant information, security of those systems and the data is paramount, said Paul Thomas, space innovation lead for Technology Innovation at Accenture,
in a statement
.
Once efficient
quantum computing becomes a reality
, the expectation is that clusters of them will have enough gas in the tank to break RSA-2048 encryption, something that even the most powerful of todays computers are incapable of achieving.
And presumably, when that happens, there will be legions of cybercriminal types pouring out of the woodwork to decrypt the many classified secrets that organizations, governments, and critical infrastructure (including satellite arrays) use to ward off mass operational disruption.
Granted, the
timing on that breakthrough
remains a moving target, but the satellite test is a step towards prepping for that doomsday scenario. Also, by employing post-quantum encryption now, it can protect against any steal now, decrypt later plans on the part of cyberattackers who might be stockpiling encrypted data in anticipation of a literal quantum leap.
Outer space is getting more crowded and contested every day and providing reliable space-based security is critical in todays global economy, said Tom Patterson, quantum and space security lead at Accenture.
