基于身份的门限代理盲签名方案

目前基于身份、门限代理签名和盲签名有机结合的研究不多，基于此，利用椭圆曲线上的双线性映射理论和秘密共享门限签名技术，提出一种基于身份的门限代理盲签名方案。该方案解决了代理签名权力过于集中的问题，同时通过盲签名实现了签名的匿名性。理论分析表明，该方案易于实现且安全性高，适合在实际中应用。

ID-based Threshold Proxy Blind Signature Scheme

The researches on combination of identity, threshold proxy signature and blind signature are rare presently. This paper proposes an ID-based threshold proxy blind signature scheme by combining proxy signatures, threshold signatures, blind signatures and using bilinear pairing on elliptic curve. It solves the problem that potency is too centralized in proxy signature, and realizes the anonymity by blind signture. Analysis shows that the scheme is easy to carry out and has high robustness, and it is suitable for application in practice.
