Explore three cutting-edge cryptographic techniques for privacy-preserving computation in this 39-minute conference talk from the OpenSSL 2025 conference. Delve into Fully Homomorphic Encryption (FHE), Zero-Knowledge Proofs (ZKP), and Multi-Party Computation (MPC) to understand how these technologies enable secure data processing while maintaining privacy. Learn the fundamental principles behind each approach, their practical applications, and how they can be implemented to solve real-world privacy challenges in distributed computing environments. Discover the strengths and limitations of FHE for performing computations on encrypted data, examine how ZKP allows verification of information without revealing the underlying data, and understand how MPC enables multiple parties to jointly compute functions over their inputs while keeping those inputs private. Gain insights into the current state of these privacy-aware computation methods and their potential impact on secure data processing across various industries and use cases.
