一个基于向量空间秘密共享的新成员加入协议
Protocol for member expansion in vector space secret sharing
摘要
Abstract
This paper puts forward a new member entry protocol which can be verified.When a new member enters the threshold system,he can choose any two old members to help produce a new secret share, which is ultimately obtained by the new member's own calculation.During the new share producing process, the new member can verify the validity of his share.Different with previous protocols,the new share is obtained by the new member's own calculation via “Black Box” in this new protocol.Comparing with the majority of previous protocols which are based on (t,n) threshold theory of Shamir,this protocol has more generality because the paper is based on vector space secret sharing.关键词
