Abstract: This study proposes a practical threshold RSA digital signature scheme based on a nesting secret sharing.Comparing with the previously proposed schemes,this study has several properties:(1)resisting conspiracy attack;(2)more participating and more representing;(3)verification with anonymity and identity can be investigated.

Key words: RSA, threshold digital signature, nesting secret sharing

摘要: 基于嵌套秘密共享的思想,提出了一种实用RSA门限签名方案,与已有的RSA门限签名相比,该方案具有以下特性:(1)抗合谋攻击能力;(2)多参与性和多代表性;(3)验证的匿名性和身份的可追查性。
