(CONNECT) Timeo Jauslin and Alain Lavoyer from the School of Engineering and Environment at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW), which is located in Windisch in the canton of Aargau, have presented their project End-to-End Quantum-Safe Security for Satellite Data Links (E2EQSS) at the Security for Space Systems (3S) Conference organized by the ESA. As is the case with the two Swiss companies Ateleris from Brugg in the canton of Aargau and id Quantique based in Geneva, FHNW forms part of a consortium headed up by the German company VisionSpace Technologies. According to a company statement of Ateleris, they were invited to present the most recent findings from its project work at the ESA conference.
With E2EQSS, the consortium is contributing to the development of secure and future-proof infrastructures for satellite communications. In its work, the group is focused on the development of an innovative end-to-end security architecture that integrates cutting-edge post-quantum cryptography and quantum-based random number generation. According to the information, this approach is intended both to protect low-rate TT&C links and high-rate payload data transmissions, thereby ensuring resilience against future quantum threats over the long term.
In the project, Ateleris is responsible for looking after the space segment. The company’s CEO Laszlo Etesi points out that until recently security has often been overlooked in civil space systems. “However, the industry is now recognizing how critical secure access and communication are for satellite infrastructure”, he states, adding that he is “proud to say that we can already demonstrate a robust, working prototype, showing that end-to-end quantum-safe security for satellite links is moving from concept to reality”. According to the information, the presentation generated significant interest. ce/mm
