Zero-Knowledge Federated Learning with Lattice-Based Hybrid Encryption for Quantum-Resilient Medical AI

Researchers introduce ZKFL-PQ, a quantum-resistant cryptographic protocol for federated learning in medical AI that combines zero-knowledge proofs, lattice-based encryption, and homomorphic encryption. The protocol achieves 100% rejection of malicious updates while maintaining model accuracy, addressing vulnerabilities from gradient inversion attacks and future quantum threats.
