The main research topics of SCNL are related to Satellite Communications and Networking and Cybersecurity.

In detail, the main research activities currently addressed are:

 

Non-Terrestrial Networks (NTN)

 

NTN integration in B5G / 6G

NTN 5G scenario

Non-Terrestrial Networks (NTN) became a viable solution to improve the current Internet connectivity in the vision of the Beyond 5G (B5G) / 6G frameworks. Satellites, UAVs, and HAPS can offer higher coverage, reliability, and extend Internet connection to rural and remote areas where there is no other kind of telecommunication infrastructure (and the cost to build a terrestrial network from scratch would be prohibitive). 
However, the employment of networking solutions designed and developed for terrestrial networks is not straightforward.

Routing and Handover in Mega-LEO satellite networks

Industries and companies such as SpaceX, OneWeb, and Amazon, are designing and launching constellations made of thousands of Low Earth Orbit (LEO) communication satellites to contribute building a universal “Space Internet” able to support the classical and legacy terrestrial Internet. However, a lot of challenges from several viewpoints are still open, such as how to route the information throughout this network and how to manage the handover mainly caused by the fast-moving LEO satellites considering the strict hardware constraints of these space nodes.

Orbital Edge Computing

Mega-LEO satellite constellations are becoming a reality. Thousands of LEO satellites are orbiting the Earth mainly to offer worldwide Internet access, even if next-generation satellites could be also exploited for something else. Terrestrial users can benefit from offloading computational tasks to Orbital Edge Computing (OEC) platforms where tasks are processed onboard satellites. 
However, further improvements are still achievable considering multiple aspects, such as how to perform the computing sharing in this distributed orbital platform and which network information can be used.

Satellite RF data analytics

Among the applications envisioned for satellites, Radio Frequency (RF) data analytics is one of them. Satellites will act as data collectors gathering a lot of data that will be then processed together to address specific tasks, such as the identification of a sender node from information that can be extracted by its generated signals and not related to the application data stored within each data packet. 
However, several challenges have still to be faced and research work to do related to specific aspects, such as the possible exploitation of ML techniques.

Satellite Cybersecurity

Recent competitions and challenges, such as Hack-A-Sat (https://hackasat.com/), showed how satellite systems can be appealing to hackers and prone to cyber-attacks, ranging from the simple satellite service disruption to the more dangerous partial or full control of the deployed satellites. 
However, simply applying protection systems designed and used in terrestrial networks may not be an always applicable and useful solution. Besides, proper training of the satellite users and operators is needed to allow them to properly consider this aspect and implement the fundamental security-by-design principle.

Cybersecurity


UAV for localization and anomaly detection in IoT scenarios 

Unmanned Aerial Vehicles (UAVs) are deployed and used for multiple purposes. One of them is related to telecommunication and involves properly equipped UAVs to fly above certain areas in order to collect data sent by underlying IoT nodes. This application has its role especially in rural areas but also in urban scenarios, if these flying nodes are exploited for additional tasks, such as cybersecurity-related tasks. 
However, multiple technological aspects still have to be considered and addressed to properly unleash the full potential of these devices, considering the different kinds of information they can collect and how they can interact with the other terrestrial and non-terrestrial network nodes.

Security assessment of systems with wireless communication interfaces

Nowadays, a higher number of systems are equipped with ICT technologies to improve them and offer additional functionalities to authorised users. Such improvements made these systems generate more data and connect to the Internet to allow authorised personnel to remotely see these data and manage the related apparatus. 
However, the cybersecurity aspect is often underestimated, making these systems suffer from cyber threats and vulnerabilities that can be exploited by malicious users. An important aspect is to develop a universal tool for the system’s security assessment aims to verify the system’s security level by testing the different possible interfaces that unauthorised people can exploit to make attacks, such as the wireless communication interfaces.

Anomaly detection in Industrial Control Systems

Smart Grids represent the new paradigm of evolution of electricity grids. Power grids implement a growing variety of control systems based on ICT technologies to meet the needs of real-time monitoring and control. Distributed energy sources, storage systems, and Vehicle-to-Grid provide the main examples. This evolution significantly extends the attack surface. The action of smart-grid protection must be approached from different perspectives, including Network Security and Cyber-physical security, starting from the observation that the control networks themselves carry information on the physical behavior of a process and for this reason they must respect the laws of physics that govern the process itself.  An anomaly can, therefore, be identified as a particular operational condition of the infrastructure as a whole, including both the network of controllers and the controlled process. 
The aim is the development of monitoring algorithms relying on an integrated approach that can significantly benefit from the use of Machine Learning (ML), which plays a crucial role.
