Scalable Mixed-Mode MPC
Mixed-mode MPC framework scalable to 100+ parties using threshold homomorphic encryption
Designed an efficient multiparty lookup table protocol based on threshold homomorphic encryption, enabling highly scalable mixed-mode MPC supporting 100+ parties with up to 1000× less communication than prior work.
- Designed conversion protocols between arithmetic, Boolean, and Yao representations using the lookup table primitive.
- Implemented a full mixed-mode MPC framework supporting large-party settings at practical performance.
