Verifiable Secure Aggregation via Dual Servers with Linear Tags in Federated Learning
The paper proposes a secure and verifiable aggregation scheme for Federated Learning using a non-colluding dual-server architecture and linear tags, which significantly enhances user privacy and reduces computational overhead compared to existing methods.
Privacy-Preserving High-Resolution Image Gradient Computation Based on Fully Homomorphic Encryption
The paper proposes a multi-ciphertext privacy-preserving framework to efficiently compute high-resolution image gradients using Fully Homomorphic Encryption (FHE) by dividing the large image into smaller sub-images.
