Publicly Verifiable Secret Sharing Scheme

Abstract

A Publicly Verifiable Secret Sharing(PVSS) scheme is a verifiable secret sharing scheme with the property that the validity of the shares distributed by the dealer can be verified by any party,hence verification is not limited to the respective participants receiving the shares.So there are more application fields than a verifiable secret sharing.A non-interactive and information-theoretic PVSS scheme based on public cryptography and the zero-knowledge proof of knowledge were presented.It is very simple to implement,extend and renew this scheme,which especially fits the publicly verifiable secret sharing for general access structure.
