I am using the threshold FHE in my program for multi-party, specifically the threshold BGV. Is there paper about the detailed implementation of how threshold FHE is implemented in openFHE? Thanks for your reply!

A high-level webinar is available at [Homomorphic Encryption for OpenFHE Users – OpenFHE.org](https://www.openfhe.org/portfolio-item/homomorphic-encryption-for-palisade-users-5/)

The closest paper is probably [Multiparty Homomorphic Encryption from Ring-Learning-With-Errors](https://eprint.iacr.org/2020/304). We developed this capability independently by extending the ideas/algorithms from [Multiparty Computation with Low Communication, Computation and Interaction via Threshold FHE](https://eprint.iacr.org/2011/613). Our team described only the algorithms for CKKS in Appendix C of [Collaborative Privacy-Preserving Analysis of Oncological Data using Multiparty Homomorphic Encryption](https://eprint.iacr.org/2023/1203).
