The European Infrastructure for Resilience, Interconnectivity and Security by Satellite (IRIS2<\/sup>) promises a powerful new space-based communication infrastructure for the EU. This ambitious venture is an opportunity to make use of critical novel technologies.<\/p>

Author: Prof. Symeon Chatzinotas, head\u00a0<\/i>of the<\/i>\u00a0Signal Processing and Communications (SIGCOM) research group.<\/i><\/p>

IRIS2<\/sup><\/a>\u00a0is set to be operational by 2027, and it consists of hundreds of satellites in a multi-orbit constellation. It will be the first European satellite constellation to offer secure communication services on such a large scale, offering connectivity for both\u00a0government\u00a0users and mass market purposes. The use cases include command and control of key infrastructure like energy grids, defence and crisis\u00a0management,\u00a0mobile and broadband coverage to remove internet dead zones in remote areas, as well as providing back-up for terrestrial communications infrastructure. It is an ambitious plan from the European\u00a0Commission\u00a0and follows on previous constellations like Galileo or the Sentinel missions concerning navigation services and earth\u00a0observation, respectively.\u00a0<\/p>

The announced set-up for the satellite constellation\u00a0is the right direction for building a secure satellite communication system for Europe. Yet, three novel technologies might provide an edge to this European venture:\u00a0quantum communication services, artificial intelligence, and direct satellite access through 5G. To make use of these three innovation areas, advanced research and development\u00a0should\u00a0accompany\u00a0this\u00a0EU endeavor.<\/p>

First, while quantum communication is already envisaged in the context of the\u00a0IRIS2<\/sup>programme, further developments are needed to increase the technology readiness.\u00a0The first use case of quantum communication is to exchange encryption keys over quantum channels which are then used to encrypt sensitive data over digital communication channels. The current IRIS\u00a0<\/sup>programme includes secure quantum encryption\u00a0based\u00a0on the European Quantum Communication Infrastructure (EuroQCI). However, there are certain areas of quantum communication in IRIS2<\/sup>that\u00a0deem special attention, i.e.\u00a0efficient orchestration of the end-to-end service, including key exchange, key storage, key management and integration with parallel technologies, such as post-quantum cryptography and public key infrastructure.\u00a0\u00a0<\/sup>2<\/sup>\u00a0<\/sup><\/p>

Second, artificial intelligence can be used to\u00a0manage the\u00a0ground and space components of\u00a0IRIS2<\/sup>. The entire system will be massive, consisting\u00a0of\u00a0satellites,\u00a0ground stations,\u00a0and\u00a0end users. This makes it a very complex system where resources must be allocated optimally and\u00a0dynamically,\u00a0but this comes in the expense of high computational complexity. However, with a sufficient preparatory training,\u00a0small,\u00a0lightweight artificial intelligence modules can be integrated into the set-up to allow the system to perform near-optimally.<\/p>

Third, planning for a future where user terminals (such as tablets, phones, and servers), can connect directly to satellite through\u00a05G or 6G would make communication over IRIS2<\/sup>\u00a0more user-friendly. This is cutting-edge technology that promises seamless network access independently of the user location, access point or data route. SIGCOM along with international partners has recently conducted a first-ever successful demonstration, proving the potential of this technology.\u00a0\u00a0Enabling users to connect with the\u00a0IRIS2<\/sup>\u00a0system in this way will make it even more effective. For example, in emergency scenarios first responders could use their smartphone seamlessly despite any disruption to terrestrial networks.\u00a0\u00a0<\/p>

The IRIS2<\/sup>programme will also have a major impact on the Luxembourgish space sector. The Luxembourgish space sector is a very strong and vibrant space ecosystem active in the governmental satellite communication (GovSatCom) area. This includes a range of\u00a0space companies here that are leading the industry in the roll-out of space quantum and 6G technologies.\u00a0Luxembourg has all the necessary ingredients to be very actively involved in this ambitious European endeavor.\u00a0\u00a0<\/sup><\/p>
