摘要: 提出了一种安全高效的基于身份的门限签名方案,在标准模型下证明了其在适应性选择消息攻击及身份攻击下能抵抗存在伪造。无需可信中心来分发签名成员的密钥,密钥管理简单。与现有的标准模型下基于身份的门限签名相比,安全性相同,执行效率更高,更适合实际应用。

Abstract: An efficient and provably secure identity-based threshold signature scheme is proposed. The scheme is existentially unforgeable against adaptively chosen message and ID attack in the standard model.The key management is simple since there is no trusted center.Compared with the known identity-based scheme secure in the standard model,it is more efficient with the same security and suitable to be applied in the actual world.

Key words: ID-based threshold signature, without trusted party, standard model, bilinear pairings
