| 摘 要： | 门限签名是一种特殊的数字签名,它在现实生活中具有广泛的用途;一个门限签名方案是指n个成员组成的群中,群中任何不少于t个成员合作就能产生签名,然而任何少于t个成员合作都无法伪造签名,文章提出了一种新的基于离散对数问题和分组秘密共享的门限签名方案,该方案具有消息保密性、可公开验证性和公开信道授权的优点.

| Abstract: | Threshold signature,a special kind of digital signature,is in popular use.A t out of n threshold signature scheme is a protocol that only t or more than the threshold number members in the group can generate a valid signature,while fewer than t players cannot create a valid signature in the protocol.A new type threshold group signature scheme with the security of the discrete logarithm is proposed based on the block secret sharing scheme.The scheme has some merits in secrecy,public verifiability and pubic d... |
