Secure Multi-Party Computation (SMPC) is an important subset of cryptography. It has the potential to enable real data privacy. SMPC seeks to find ways for parties to jointly compute a function using their inputs, while keeping these inputs private. Shamir’s Secret Sharing Scheme: To understand SMPC, we must first understand Shamir’s Secret Sharing Scheme. The Scheme’s purpose is to divide and distribute one secret value over several nodes or users, so that no one knows anything about the secret value. To retrieve the secret value, a minimum quorum of users must pool their data together. Shamir’s Secret Sharing Scheme can also be used to perform computations on a secret shared value. When we group together the results of each user’s computations on their respective pieces of data, we arrive at the outcome of the computation — without knowing the secret inputs. |
