What is additive secret sharing?
The simplest example of a Secret Sharing Scheme is Additive Secret Sharing which involves breaking a numeric secret into fragments that add up to the original secret. Once divided into shares, each share is distributed to different participants.
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 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].
