WebApr 14, 2024 · However, data leakage still remains an issue. In this paper, we propose xMK-CKKS, a multi-key homomorphic encryption protocol to design a novel privacy-preserving federated learning scheme. In this scheme, model updates are encrypted via an aggregated public key before sharing with a server for aggregation. WebNov 14, 2024 · This paper focuses on solving the privacy and security issues for score-type e-voting applications based on cryptographic technology. In order to solve such issues, we propose an electronic scoring scheme based on the CKKS(Cheon-Kim-Kim-Song) homomorphic encryption algorithm. It supports floating-point computing for exploiting …
