IEEE 802.1 Zaman Hassas Araç-İçi Haberleşme Ağları için Siber Güvenlik: Güncel Gelişmeler ve Hizmet Reddi Saldırılarının Etki Analizi

Öz

Adanmış bilgisayarlar, araç-içi mimariler gibi Siber Fiziksel Sistemlerin operasyonunu sensörler ve aktüatörler yardımıyla kontrol ederler. Araç-içi platformlar için gerçek-zamanlı haberleşme teknolojilerinin güvenli hale getirilmesi araştırma topluluklarının dikkatini çekmektedir. IEEE 802.1 Zaman Hassas Haberleşme (ZHH) görev grubu, yüksek bant genişliği ve düşük maliyeti nedeniyle, Ethernet tabanlı deterministik iletişim teknolojilerinin standardizasyonunu hedeflemektedir. IEEE P802.1DG çalışma grubu, gelecek nesil araç-içi platformlarda yaygın olarak kullanılması öngörülen ZHH teknolojisine dayalı, güvenli ve gerçek-zamanlı otomotiv gömülü sistem profili tanımlamaktadır. Bu makalede, ZHH’yı destekleyen araç-içi haberleşme ağlarının güvenliği ile ilişkili araştırma çalışmalarının kapsamlı bir incelemesi sunulmakta ve araç-içi haberleşme ağlarındaki gerçek zamanlı trafiği hedef alan Hizmet Reddi (HR) saldırı senaryoları tanımlanmaktadır. Saldırı senaryolarımızın, değişken boyutlara sahip iki farklı, gerçekçi araç-içi haberleşme ağlarının performansı üzerindeki etkisi analiz edilmektedir. Deney sonuçlarımız, HR saldırılarının ZHH uyumlu bir araç-içi haberleşme ağındaki güvenlik-kritik fonksiyonların sağlıklı işlevini kesintiye uğratacak ciddi sonuçlara yol açabileceğini göstermektedir.

Cyber Security for IEEE 802.1 Time Sensitive In-Vehicle Networking: Recent Advances and Impact Analysis of DoS Attacks

Öz

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.
