Researchers at Virginia Tech and the University of Michigan-Dearborn experimentally evaluated IEC 62351-compliant Message Authentication Code, a rule-based Intrusion Detection System, and their hybrid integration for securing IEC 61850 GOOSE communication. The hybrid approach effectively mitigates replay, masquerade, and flooding denial-of-service attacks while introducing latencies under one millisecond, enhancing digital substation cyber resilience.
Key insights
- Individual real-time mitigation techniques exhibit complementary strengths; MAC verification counters masquerade and flooding attacks, while rule-based IDS protects against replay attacks.
- A hybrid approach integrating MAC verification with a rule-based IDS provides enhanced protection, effectively mitigating replay, masquerade, and flooding DoS attacks in IEC 61850 GOOSE communication.
- All evaluated mitigation methods, including the hybrid solution, introduce processing latencies of less than 1 ms, confirming their viability for real-time application in digital substations.
