Secret sharing schemes in cryptography

Secret Sharing refers to cryptographic methods for taking a secret, breaking it up into multiple shares, and distributing the shares among multiple parties, so that only when the parties bring together their respective shares can the secret be reconstructed.

What is the main purpose of secret sharing?

The goal of secret sharing is for all authorized sets of users/shares to be able to reconstruct the secret, while all unauthorized sets learn nothing.

What is secret splitting and sharing?

In secret splitting protocols, n cipher-text are required to. recover the original message. On the other hand, in the secret sharing protocol, only m cipher- text from a total of n cipher-text are needed to recover the original message. This scheme is.

What a threshold scheme does for secret sharing?

A (t,n) threshold secret sharing scheme enables the sharing of a secret among n players such that any t of the players can later recover the secret from their shares, while any less than t players cannot.
