“…al. [21] and Bello and Steiner [22] highlight that ensuring security is a crucial design issue for TSN by emphasizing that more research is needed on security in TSN including the early detection of cyber threats. Maximizing security in TSN under time-constrained conditions formulated as an optimization problem, Mahfouzi et al [23] takes the time duration required by the tasks of encryption/decryption into consideration to compute the routes and scheduling tables for the data streams.…”

Dedicated computers control the operation of Cyber Physical Systems such as in-vehicle architectures with the help of sensors and actuators. Securing the real-time communication technologies for in-vehicle platforms attracts the attention of the research community. IEEE 802.1 Time Sensitive Networking (TSN) task group targets the standardization of Ethernet-based deterministic communication technologies due to its high bandwidth and low cost. IEEE P802.1DG working group specifies the profile for secure and real-time automotive embedded systems relying on TSN, which is envisioned to be widely used in future in-vehicle platforms. In this paper, we present an elaborate review of the research work on the security of in-vehicle communication networks with TSN support, and define various Denial of Service (DoS) attack scenarios targeting the real-time traffic in in-vehicle networks. We evaluate the impact of our attack scenarios on the performance of two different realistic in-vehicle communication networks with varying sizes. Experimental results show that DoS attacks can lead to severe consequences disrupting the healthy operation of safety-critical functions in a TSN-compliant in-vehicle network.

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 essential. However, IEEE 802.1CB does not come with security guarantees. Indeed, as we show in this paper, an attacker may be able to exploit different threat vectors to impair the correctness of communication, impacting on the safety of users. Due to TSN strict delay and reliability requirements, classical security solutions can not be easily applied without significant efforts. Therefore, researchers proposed multiple solutions to guarantee secure communication. However, the current state-of-the-art is not able to guarantee both security and timing guarantees.In this paper, we provide a detailed analysis of the security of IEEE 802.1CB exploiting the STRIDE methodology. Compared to the existing state-of-the art on the subject, we provide a deeper analysis of the possible threats and their effect. We then analyze available solutions for security in IEEE 802.1CB, and compare their performance in terms of time, reliability, and security guarantees. Based on our analysis, we show that, although there exist promising solutions trying to provide security to 802.1CB, there is still a gap to be filled both in terms of security and latency guarantees.

Advances in automotive technology require networks to support a variety of communication requirements, such as reliability, real-time performance, low jitter, and strict delay limits. Time-Sensitive Network (TSN) is a keyframe transmission delay-guaranteed solution based on the IEEE 802 architecture of the automotive Ethernet. However, most of the existing studies on automotive TSN performance are based on a single mechanism, lacking a complete and systematic research tool. At the same time, the design method should be considered from a global perspective when designing an automotive TSN system, rather than only considering a single mechanism that TSN applies to. This paper discusses the correspondence between traffic types and automotive scenarios and proposes a methodology to target the delay constraint of traffic types as the design goal of automotive TSN networks. To study the performance of automotive TSN under different mechanisms such as time-aware shaper (TAS), credit-based shaper (CBS), cyclic queuing and forwarding (CQF), etc., this paper also develops a systematic automotive TSN simulation system based on OMNeT++. The simulation system plays a crucial role in the whole methodology, including all applicable TSN standards for the automotive field. Lastly, a complex automotive scenario based on zonal architecture provided by a major motor company in Shanghai is analyzed in the simulated system; verifying TSN can guarantee real-time performance and reliability of the in-vehicle network.
