Explore secure multi-party computation in this comprehensive conference talk from ACCU 2023. Learn how to jointly compute on private data without revealing inputs while still obtaining outputs. Discover protocols and techniques for scenarios where a mutually trusted party is unavailable. Delve into concepts like homomorphic encryption, garbage circuits, and secret sharing using high-school level algebra. Gain insights into the history, security properties, and practical applications of secure multi-party computation. Understand additive secret sharing, equal sharing, and resharing techniques to enhance data privacy and collaboration in computational tasks.
