摘要
将L.Cha和L.Cheon基于身份的签名方案加以改进,应用在门限签名方案中,提出了一个基于GDH群的安全有效的门限签名方案。方案具有短签名的计算量小,通信量少等特性,并能有效的防止伪造和欺骗攻击,是一个安全有效的基于GDH群的分布式数字签名方案。
By improving the identity-based signature scheme of L. Cha and L. Cheon and then applying it in threshold signature scheme, in this paper a secure and efficient threshold signature scheme based on GDH group is proposed. This scheme has the characteristics of small computation complexity and low traffic that the short signature possesses, and can prevent from forgery and spoofing attack effectively. It is a secure and effectual GDH group-based distributed digital signature scheme.
