Halder, Subir (author), Ghosal, Amrita (author), Conti, M. (author)Networks of Unmanned Aerial Vehicles (UAVs) are emerging in many application domains, e.g., military surveillance. To perform collaborative tasks, the involved UAVs exchange several types of information, e.g., sensor data and commands. The major question here is how to schedule the tasks under dynamic traffic flows to provide network services...journal article 2023

Ahmadvand, Hossein (author), Lal, C. (author), Hemmati, Hadi (author), Sookhak, Mehdi (author), Conti, M. (author)In recent years, the use of Software Defined Networking (SDN) has increased due to various network management requirements. Using SDN in computer network applications has brought several benefits to users, including lower operational costs, better hardware management, flexibility, and centralized network deployment. On the other hand, the...journal article 2023

de Vos, Adriaan (author), Brighente, Alessandro (author), Conti, M. (author)IEEE 802.1CB provides a standard for reliable packet delivery within Time-Sensitive Networking (TSN). As this standard is envisioned to be used in mission-critical networks in the near future, it has to be protected against security threats. The integrity of the network communication should be the biggest focus as guaranteed delivery is...conference paper 2023

Cardaioli, Matteo (author), Conti, M. (author), Orazi, Gabriele (author), Tricomi, Pier Paolo (author), Tsudik, Gene (author)Authentication and de-authentication phases should occur at the beginning and end of secure user sessions, respectively. A secure session requires the user to pass the former, but the latter is often underestimated or ignored. Unattended or dangling sessions expose users to well-known Lunchtime Attacks. To mitigate this threat, researchers...journal article 2023

Spolaor, Riccardo (author), Liu, Hao (author), Turrin, Federico (author), Conti, M. (author), Cheng, Xiuzhen (author)The literature and the news regularly report cases of exploiting Universal Serial Bus (USB) devices as attack tools for malware injections and private data exfiltration. To protect against such attacks, security researchers proposed different solutions to verify the identity of a USB device via side-channel information (e.g., timing or...conference paper 2023
