We are delighted to announce that our paper titled "Preemptive DoS attacks on Time Sensitive Networks" has been accepted for presentation at GLOBECOM 2023. We look forward to sharing our findings and engaging in insightful discussions with fellow academics at the conference.

Abstract:

Time-sensitive networking (TSN) is a promising technology for real-time communication in industrial and automotive networks. The frame preemption is one of its key features, which allows high-priority traffic to interrupt the transmission of low-priority traffic to decrease the delay of critical traffic. However, the deterministic nature of TSN frame preemption also renders it vulnerable to denial of service (DoS) attacks that can significantly reduce the quality of service (QoS) of flows by increasing delays and packet loss. This paper introduces the concept of preemptive DoS attacks and evaluates their impact on TSN QoS performance. For that, we describe a strategy that attackers can use to estimate the used preemption scheme in the switch and then show how an active attacker can use this information to degrade the QoS of TSN. Our simulation results indicate that even a single attacker can significantly deteriorate the QoS of TSN traffic.
