摘要/Abstract

摘要：

高可靠性的时间同步是车载时间敏感网络面临的重要挑战。针对现有方法在冗余与安全方面的不足，提出了一种元启发式算法优化冗余路由方案，提高节点路由的冗余性；并提出鲁棒同步域选择算法有效抵抗内部节点攻击的影响，保证时间同步的安全性。该算法基于软件定义网络形成集中式配置架构。实验结果表明，所提出的路由方法相较于K-最短路径方法在冗余程度上有55.2%的提升，鲁棒同步域选择算法相较于Huber回归算法在崩溃点上有43.3%的提升。仿真结果表明，在汽车集中式电子电气架构拓扑中，所提出的时间同步架构确保链路冗余的同时可以抵御内部节点攻击的影响。

Abstract:

Highly reliable time synchronization presents a significant challenge for vehicle-based time-sensitive networks. Addressing the shortcomings of existing methods in redundancy and security, a meta-heuristic algorithm is proposed to optimize redundant routing schemes, enhancing the redundancy of node routing. Additionally, a robust synchronization domain selection algorithm is introduced to effectively counteract the impact of internal node attacks, ensuring the security of time synchronization. This algorithm forms a centralized configuration architecture based on software-defined networking. Experimental results demonstrate that the proposed routing method achieves a 55.2% improvement in redundancy compared to the K-shortest path method. The robust synchronization domain selection algorithm exhibits a 43.3% improvement in crash points compared to the Huber regression algorithm. Simulation results indicate that within automotive centralized electronic/electrical architecture topologies, the proposed time synchronization architecture ensures link redundancy while mitigating the impact of internal node attacks.

Key words: time-sensitive networking (TSN), time synchronization, multi-domain redundancy, service security and reliability
