Secure Multi-Party Computation

Secure Multi-Party Computation (SMPC) is a method that allows multiple parties to collaboratively compute a function over their combined data without revealing any individual inputs to each other. For example, imagine a group wanting to determine the average score of their tests without sharing their actual scores. SMPC enables them to calculate this average securely, ensuring privacy. Each participant contributes only encrypted information, and the final result is shared without exposing sensitive data, thus fostering trust among parties while protecting their privacy.
