具有特权者的门限签名方案
Threshold signature scheme with privileged member.
摘要
Abstract
After in-depth study on the threshold schemes,a new scheme is proposed. The scheme can withstand all kinds of the existing attacks because some privileges are given to the designated clerk. Compared with the existing schemes,it can efficiently protect the identities of the signers who participate in signing a message. Even all members' identities of a group who signs a message are opened because of a dispute,none but the designated clerk can know which are done by the members in the previous signatures. Correctness and security of the new scheme are analyzed. The result shows that this scheme is secure.关键词
