针对现有基于(t,n)门限结构的门限签名方案的应用局限性,将一般访问结构上的秘密共享方案与基于(t,n)门限结构的门限签名方案相结合,提出了一种一般访问结构上的门限签名方案. 详细介绍了所提方案的部分签名与群签名的生成和验证过程,并证明了该方案的有效性和安全性.
針對現有基于(t,n)門限結構的門限籤名方案的應用跼限性,將一般訪問結構上的祕密共享方案與基于(t,n)門限結構的門限籤名方案相結閤,提齣瞭一種一般訪問結構上的門限籤名方案. 詳細介紹瞭所提方案的部分籤名與群籤名的生成和驗證過程,併證明瞭該方案的有效性和安全性.

To the applied limitation of the existing threshold signature schemes based on the (t, n) threshold structure, a new threshold signature scheme based on the general access structure is proposed through combining the secret sharing scheme based on the general access structure and the threshold signature scheme based on the (t, n) threshold structure. The generation and verification processes of the partial signature and the group signature are introduced in detail. Both the validity and security of the proposed scheme are proved.
