Abstract

As society becomes more dependent on technology and the internet, critical infrastructure, which provides the fundamental services that millions of people depend on, becomes more vulnerable to cyber threats. This paper presents the importance of cybersecurity in critical infrastructure addressing the communications sector which is prevailed by space systems. It gives an overview of laser communications via satellite, and it argues the utility that quantum cryptography can provide to secure the data transmitted between communication satellites and ground stations from cyber attacks. Common encryption algorithms are briefly introduced as well as a review on quantum computing. Quantum cryptography is still a primitive concept, but as technology advances more and more researchers are focusing their attention into this visionary cryptography system.
