The Challenge of Edge-Centric 6G IoT Security
Traditional Intrusion Detection Systems (IDS) are largely centralized, leading to bottlenecks in scaled analysis, privacy invasion, and enormous latency. These limitations are critical in the context of 6G-enabled IoT Cyber-Physical Systems (CPS), which demand distributed, intelligent, and energy-efficient security. Existing federated learning (FL)-based IDS struggle with optimizing data relevance, model sparsity, and privacy-efficiency trade-offs, resulting in high communication overhead and impaired performance under resource constraints.
Introducing L-FIDS: A Lightweight Federated IDS
The proposed Lightweight Federated Intrusion Detection Framework (L-FIDS) is a modular solution tailored for edge-centric 6G IoT CPS. It moves beyond conventional FL by embedding adaptivity into aggregation, communication, detection, and compression pipelines. L-FIDS integrates five novel analytical modules: Energy-Adaptive Federated Reinforcement Aggregation (EAFRA), Spatio-Temporal Uncertainty-aware Federated Attention Filtering (STUFAF), Lightweight Self-Evolving Edge Autoencoder Forest (LSE-EAF), Differentially Private Sparse Cluster Aggregation (DPSCA), and Federated Task-Aware Compression with Cyclical Consistency (FTAC³). These modules work synergistically to achieve decentralized, adaptive, and resource-aware IDS operations.
Core Technical Innovations
- EAFRA: Uses reinforcement learning to adjust model updates based on local energy, optimizing energy and accuracy.
- STUFAF: Applies Bayesian uncertainty with contextual metadata to prioritize informative updates, reducing false positives.
- LSE-EAF: Ensures low-latency, high-accuracy detection with minimal resources using a hybrid of anomaly detectors.
- DPSCA: Provides adaptive, privacy-preserving sparse updates to contextually clustered nodes, balancing privacy and communication costs.
- FTAC³: Compresses models via task-relevant pruning while maintaining functional consistency across nodes.
This integrated design ensures limited collaboration of edge nodes under strict energy, bandwidth, and privacy constraints, while maximizing intrusion detection performance and efficiency.
Empirical Validation & Real-World Impact
Evaluations on standard CPS benchmarks (CIC IDS2018 and TON_IoT datasets) demonstrate significant improvements:
- Energy Savings: Close to 60%.
- Communication Overhead: 70% reduction.
- Detection Accuracy: Over 93%.
- False-Positive Rates: 30% drop.
- Model Size: Over 55% reduction.
- Convergence: Faster, 12-14 rounds.
- Inference Latency: Less than 2.7 ms.
L-FIDS provides robust security even with stringent privacy budgets (ε=0.5) and ensures high per-class precision across diverse attack types, making it ideal for autonomous, resistant, and intelligent security infrastructures for 6G IoT CPS ecosystems.

Case Study: Smart Grid Intrusion Detection
In a simulated smart grid system with substations interacting via 6G-enabled IoT, L-FIDS successfully deployed on low-power edge devices (smart meters, PLCs). It achieved real-time detection of anomalies like frequency injection on Modbus TCP data with 95% precision. The system converged to a global model with high confidence within 14 communication rounds, consuming under 17.5 mWh per round, and delivering detection with less than 3 ms latency per sample. This showcases L-FIDS's capability for secure, scalable, and energy-efficient monitoring of critical infrastructure in resource-constrained edge environments.
