Abstract: The concept of proxy signature has been introduced by Mambo，Usuda and Okamoto in 1996.Lots of proxy signature has been also raised.This paper proposes a proxy-blind signature with message recovery based on bilinear pairings with points of elliptic curves.It not only has the common advantages of proxy signature and blind signature，but also makes the news recovery.This scheme can reduce communication costs and speed up the computing speed compared with [1] and [2].

Key words: elliptic curves, bilinear pairings, blind signature, proxy-blind signature, message recovery

摘要： 在1996年，代理签名的概念被Mambo等提出来后，许多代理签名方也被提出来。利用椭圆曲线上的双线性对的特性，提出具有消息恢复的代理盲签名方案，该方案不仅有代理签名和盲签名共同的优点，而且可以使消息恢复，相对比文献[1]和[2]中的消息恢复更降低了通信成本，加快了计算速度。
