  • 3. Protecting our critical infrastructure




The demands of today's system and operations maintenance, especially critical infrastructures, require a quick response and reaction. Therefore, companies offering maintenance services use remote access via VPN, which utilizes standard encryption methods to protect data.

As engineers involved in maintaining such systems, we see a problem with the current method due to the advent of quantum computers. This type of technology is becoming vulnerable and requires the development of new access methods for operators' remote connection to critical infrastructure.

Our solution to this problem is based on the use of the Eagle-1 satellite, which distributes quantum keys, and the Quantum Communication Infrastructures (QCI), which generates quantum keys and converts them into quantum tokens (USB with a list of quantum keys) according to the demand of critical infrastructure. Quantum Service Centers (QSCs), chosen by critical infrastructure, distribute the received quantum tokens to certified companies for maintaining critical infrastructure.



Our idea is based on using the Eagle-1 satellite, which is scheduled to launch in 2024. In addition to their satellite, we plan to utilize their technology for distributing and collecting quantum keys through Quantum Communication Infrastructures (QCIs) to ensure and enhance the security of future VPN communications for remote maintenance and servicing of critical infrastructures
