A3: Adaptive Attack-Aware Aggregation for Byzantine-Robust Federated Learning

H. Tariq Butt, S. Khan, K.F.A. Khan, I. Munir, S. Nazir

Springer Information Systems Frontiers

Novel Byzantine-resilient aggregation technique for federated learning achieving 94.99% average accuracy with only 0.71% variance across 5 attack types - significantly outperforming state-of-the-art methods (TrimmedMean: 2.62% variance, Multikrum: 54% variance). Features triple-weighted aggregation mechanism (diversity, confidence, trust) with adaptive strategy selection. Validated on CIC-IDS2017 dataset (2.8M network flows) with comprehensive statistical analysis.

The Practitioner's Dilemma: A Critical Review of Trade-offs between Privacy, Efficiency, and Model Utility in Federated Learning Systems

H. Tariq Butt, S. Khan, I. Munir, K.F.A. Khan, S. Nazir

Springer Computing

Comprehensive PRISMA-style systematic review quantifying the fundamental trilemma in federated learning: privacy, efficiency, and utility cannot be simultaneously maximized. Meta-analysis of 100+ papers and production systems (2022-2025). Key findings: Strong differential privacy (ε<1) causes 5-15% accuracy loss; Cryptographic security has 2-5× overhead; Communication optimization achieves 90%+ bandwidth reduction. Introduces five-dimensional assessment framework for Pareto-optimal FL designs.
