Secure Multi-Party Computation (SMPC) is a crucial technology that allows multiple parties to jointly compute functions without exposing their individual data inputs. This method is especially valuable in scenarios where trust is limited among the parties involved. Notable implementations of SMPC include J.P. Morgan’s Prime Match system for confidential trading, Google Cloud’s secure computations, and Apple’s Private Set Intersection for password security. SMPC also enables innovative solutions in secure voting and medical research, demonstrating its broad applicability across various industries, safeguarding privacy while maintaining the integrity of the computations.
Secure Multi-Party Computation (SMPC) allows multiple parties to compute functions collaboratively while ensuring that individual inputs remain private, highly relevant in untrustworthy settings.
SMPC has significant applications across various sectors, such as J.P. Morgan's trade matching, Google's cloud computations, Apple’s set intersection, and medical research partnerships.
In SMPC, secret-sharing ensures parties keep individual inputs hidden unless all cooperate, safeguarding data integrity and privacy.
The 'Envelope Trick' allows logical operations—like AND—to occur between two parties while keeping their values confidential, enhancing data secrecy.
SMPC techniques enable secure voting by aggregating results to determine consensus without revealing how individual votes were cast.
