Multi-Party Computation (MPC), also known as Secure Multi-Party Computation (SMPC), is a cryptographic protocol that distributes a computation across multiple parties where no individual party can see the other parties’ data.
Secure multiparty computation protocols can enable data scientists and analysts to compliantly, securely, and privately compute on distributed data without ever exposing or moving it.
The most central properties of MPC are1):
