How does secret sharing work?
Secret sharing works by splitting private information into smaller pieces — or shares — and then distributing those shares amongst a group or network. Each individual share is useless on its own but when all the shares are together, they reconstruct an original secret.
What is secret splitting and sharing?
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 threshold secret sharing?
A (t, n) threshold secret sharing requires t participants to use their shares for reconstruction of secret information. It is required that any number of participants lesser than t should not divulge any information about the secret. Threshold secret sharing schemes were introduced by Blakley [2] and Shamir [1].
