NATO Using Quantum Technologies to Make Communications Secure

Innovative projects led by scientists in NATO and partner countries are breaking new ground to harness the power of quantum to make communications impossible to intercept and hack. By implementing these quantum technologies in the security and defense fields, NATO may be able to protect information transmission from increasingly sophisticated hacking techniques and maintain its technological lead.

The Faculty of Electrical Engineering and Computer Science at the Technical University of Ostrava in the Czech Republic has a setup for quantum key distribution.

NATO Science for Peace and Security (SPS) Programme research and development initiatives have been studying the security-related uses of quantum technologies, addressing their three primary fields: computing, sensing, and communications. Quantum computing and sensing are improving the abilities of computer and remote measurement technologies to levels that they are not traditionally able to achieve. The most promising results in the area of quantum communications are coming from SPS activities. These projects develop systems for the encryption and secure transmission of information using quantum key distribution (QKD) and post-quantum cryptography (PQC) .

By limiting unauthorized access, they respond to growing security worries about emerging technologies, such as quantum computers that can decipher private communications.

Testing quantum key distribution (QKD)

QKD is a quantum communication mechanism to share decryption keys. This system sends an encrypted message over conventional networks while sending the decryption keys over quantum channels. This way, only the intended recipient can decode the message, making any eavesdropping impossible. This approach was used by an SPS project to successfully establish the first submarine optical fiber cable link between Italy and Malta with a prototypical QKD link.

Another SPS-upheld research drive explored QKD methods to send cryptographic keys starting with one endpoint and then onto the next, which was found many kilometers away. In the meantime, specialists at a college in the Czech Republic are concentrating on the use of QKD innovation on a 5G organization to investigate its capability to improve network protection in future correspondence frameworks.

Delivering of the exploratory quantum-safe correspondence climate that associated clients in Belgium, Malta, Slovakia, Spain, and the US.

Demonstrating post-quantum cryptography (PQC)

Dissimilar to QKD, which utilizes actual quantum properties to safeguard data, PQC involves cryptography and numerical capabilities as an elective way to deal with secure interchanges. A worldwide gathering of researchers upheld by SPS as of late exhibited that, utilizing PQC, it is feasible to safely send data without the chance of unscrambling by a programmer, even one who has a quantum PC. Through a protected convention, five examination bunches situated in Malta, Slovakia, Spain, the US, and NATO Central command in Brussels, Belgium, prevailed with regards to conveying in totally solid space, liberated from the gamble of interruption.

NATO's new Essential Idea, concurred by Partners at the 2022 Madrid Culmination, perceives the basic job of innovation, and specifically, arising and troublesome advances (EDTs), in forming the eventual fate of the Union. To investigate the potential and dangers related to EDTs, the SPS Program is supporting exploration exercises that address mechanical patterns in EDTs, such as man-made reasoning, independence, bioengineering, and particularly quantum advancements. Future SPS exercises exploring quantum will take a gander at how to coordinate both QKD and PQC to get data foundation in the best and most all-encompassing manner for the Coalition.
