Secret Sharing Schemes with Cheating Detection

摘要

A Secret sharing scheme allows a secret to be shared among a setof participants, P, such that only autho- rized subsets of P canrecover the secret, but any unauthorized subset can not recover thesecret. It can be used to protect im- portant secret data, such ascryptographic keys, from being lost or destroyed without accidentalor malicious exposure. In this paper, we consider secret sharingschemes based on interpolating polynomials.
