Ciphertext-Native Watermarking for RLWE-Based Homomorphic Encryption
Yufei Zhou, Peijia Zheng
The paper introduces methods to embed watermarks into RLWE-based homomorphic encryption ciphertexts, offering schemes that stay robust under additive and multiplicative homomorphic…
NFSA: Non-Forward Secure Aggregation with One Server via Two Layer Secret Sharing
Yufei Zhou
The paper introduces a secure aggregation protocol for federated learning that uses a two‑layer secret sharing scheme to eliminate server‑forwarded data, achieving one‑shot aggrega…
Privacy-Preserving High-Resolution Image Gradient Computation Based on Fully Homomorphic Encryption
Yufei Zhou
With growing emphasis on privacy protection, homomorphic encryption (HE) has emerged as a core method for privacy-preserving image processing, as it enables operations directly on…
Verifiable Secure Aggregation via Dual Servers with Linear Tags in Federated Learning
Yufei Zhou
Federated learning (FL) enables collaborative model training by aggregating local updates without requiring raw data sharing. However, prior studies have shown that servers can exp…
