This is an implementation of Shamir's Secret Sharing scheme on the BN254 field using the arkworks library. It allows splitting a secret into multiple shares such that the secret can only be reconstructed when a minimum number of shares (threshold) are available. This ensures both fault tolerance and security for sensitive information.
Shamir's Secret Sharing is a cryptographic technique that allows a secret (e.g., a password, private key, or any sensitive data) to be divided into ( n ) shares. To reconstruct the secret, at least ( k ) (threshold) shares are required. It is based on polynomial interpolation and works over a finite field.
- Security: With fewer than ( k ) shares, the secret cannot be reconstructed.
- Fault Tolerance: Even if some shares are lost, the secret can still be recovered using any ( k ) shares.
