摘要
公开的可验证秘密共享(PVSS)方案是一种任何一方均能公开地验证共享正确性的可验证秘密共享方案,验证并不局限于共享所属的参与者本人,所以它比一般的可验证秘密共享方案有着更广泛的应用。提出了一个基于公钥密码和零知识证明的,非交互式的,信息论安全的PVSS方案。该方案实现简单,且易于扩展和更新,特别适宜于一般接入结构上公开的可验证秘密共享。
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.
