Analog Multi-Party Computing: Locally Differential Private Protocols for Collaborative Computations. (arXiv:2308.12544v1 [cs.DC])

We consider a fully decentralized scenario in which no central trusted entity
exists and all clients are honest-but-curious. The state-of-the-art approaches
to this problem often rely on cryptographic protocols, such as multiparty
computation (MPC), that require mapping real-valued data to a discrete
alphabet, specifically a finite field. These approaches, however, can result in
substantial accuracy losses due to computation overflows. To address this
issue, we propose A-MPC, a private analog MPC protocol that performs all
computations in the analog domain. …
