基于双线性对的门限代理盲多重签名方案

Threshold proxy blind multi-signature scheme based on bilinear pairings

该方案是门限代理多重签名与盲签名的有机集成,既解决了代理签名方案中代理签名人权利过于集中的问题,又通过盲签名实现了签名的匿名性和不可追踪性。在该数字签名方案的基础上,采用双线性对的签名和验证方式,提出了基于双线性对的门限代理盲多重签名方案,极大地提高了门限代理盲多重签名的安全性和实现速度。

The scheme combined a threshold proxy muhi-signature scheme and a blind signature one, it not only distributed the power of the proxy signer ,but also realized the anonymity and non-trail in signature by using a blind signature scheme. Based on this new method, and using bilinear pairings, presented a threshold proxy blind multi signature scheme based on bilinear pairings. Because of using bilinear pairings, the security and speed of threshold proxy blind multi-signature was greatly enhauced.
