What is Multi-Party Computation (MPC)?

Multi-Party Computation (MPC) is a cryptographic protocol that enables multiple parties to jointly compute a function over their inputs while keeping those inputs private. Think of it like this: several people want to calculate the average of their salaries, but they don't want to reveal their individual salaries to each other. Using MPC, they can perform this calculation securely, and only the final average is revealed, while their individual salaries remain secret.

The core idea behind MPC is to distribute the computation across multiple parties in such a way that no single party can learn anything about the other parties' inputs. This is achieved through various cryptographic techniques, such as secret sharing, homomorphic encryption, and garbled circuits. These techniques ensure that the data is always processed in an encrypted or masked form, preventing any party from accessing the raw data. The power of MPC lies in its versatility. It can be applied to a wide range of applications, from secure auctions and voting to privacy-preserving machine learning and data analysis. Its ability to protect sensitive data while enabling collaborative computation makes it an invaluable tool in today's data-driven world.

History and Myths of MPC

The history of Multi-Party Computation (MPC) dates back to the 1970s, with the seminal work of Andrew Yao on Yao's Millionaires' Problem. This problem, which asks how two millionaires can determine who is richer without revealing their actual wealth, laid the foundation for modern MPC protocols. However, for many years, MPC remained largely a theoretical concept due to its computational complexity and lack of practical applications.

One common myth about MPC is that it is too slow and impractical for real-world use. While early MPC protocols were indeed computationally expensive, significant advancements have been made in recent years. Modern MPC protocols are now capable of handling complex computations with reasonable performance, making them suitable for a wide range of applications. Another myth is that MPC is only useful for highly sensitive data. While MPC is certainly valuable for protecting sensitive information, it can also be used to improve the security and efficiency of various computations, even when the data is not particularly sensitive. For example, MPC can be used to securely outsource computations to untrusted cloud providers, ensuring that the data remains protected even if the cloud provider is compromised.
