Secret Sharing Schemes are cryptographic methods that allow a secret to be divided into multiple parts, or shares, which can be distributed among a group of participants. Each participant receives a share, and only a specific number of shares, known as the threshold, are needed to reconstruct the original secret. This ensures that no single participant can access the secret alone. These schemes enhance security by preventing unauthorized access and ensuring that the secret remains safe even if some shares are lost or compromised. Shamir's Secret Sharing is a well-known example, where polynomial interpolation is used to create the shares.
