Enhancing Security in Time-Sensitive Networks: Simulation and Evaluation of PSFP

Abstract

Time-Sensitive Networking (TSN) standards provide Ethernet with real-time capabilities crucial for applications like industrial automation and autonomous systems. Among these, Per-Stream Filtering and Policing (PSFP) is designed to secure networks by mitigating unauthorized or malicious traffic. This paper outlines the security capabilities of PSFP, focusing on its ability to counter attacks such as frame injection. Using OMNeT++ simulations, we validate PSFP’s effectiveness in filtering injected frames based on stream parameters, demonstrating its relevance for robust TSN deployment in critical environments.
