摘要: 利用椭圆曲线上的双线性映射、门限多重签名和签名盲化技术,提出一个基于身份的门限多重盲签名方案,分析了方案的盲性以及安全性。该方案具有盲性、不可伪造性等安全特征,可有效地阻止敌人窃取主密钥以及子秘密,并且能够利用多重签名的保证签名的不可否认性。

Abstract: This paper presents an identity-based threshold blind multi-signature from bilinear pairings on the elliptic curve by adopting threshold cryptography and blind signature scheme.It analyzes the security and efficiency of this scheme.This scheme has several security characteristics,such as blindness,non-forgery,etc.

Key words: threshold signature, blind multi-signature, elliptic curve cryptosystem
