Security Analysis of the TSN Backbone Architecture and Anomaly Detection System Design Based on IEEE 802.1Qci

Table 1

TSN standard overview.

Standard	Status	Purpose	Application scenario
IEEE 802.1AS-2020 [7]	Proposed	Timing and synchronization	As the time-base for every node connected in the TSN, fault-tolerant time synchronization with the backup grandmaster.
IEEE 802.1Qbv-2015 [8]	Proposed	Time-aware traffic shaping	Periodic critical sensors; closed-loop control (e.g., steering and braking)
IEEE 802.1Qbu-2016 [9]	Proposed	Frame pre-emption	Strongly critical data (e.g., steering and braking actuation), usually be used in cooperating with IEEE 802.1Qbv
IEEE 802.1Qci-2017 [10]	Proposed	Filtering and policing	Network protection, intrusion detection for malicious attacks, or DoS attacks
IEEE 802.1Qch-2017 [11]	Proposed	Cyclic traffic shaping	Periodic sensors
IEEE 802.1Qcr-2020 [12]	Proposed	Asynchronous traffic shaping	Aperiodic traffic
IEEE 802.1CB-2017 [13]	Proposed	Redundant communication	Fail-operational applications tolerating nodes or wire faults
P802.1DG [14]	Draft	TSN profile for automotive in-vehicle Ethernet communications	Profiles for secure, highly reliable, deterministic latency, automotive in-vehicle bridged IEEE 802.3 Ethernet networks based on IEEE 802.1 TSN standards and IEEE 802.1 security standards
