| 摘 要： | 代理多重签名是原始代理签名的一种拓展,它是指两个或两个以上原始签名者委托代理人实施签名权利。对一个安全的代理签名方案来讲,如果能缩短它的签名长度,对一些带宽受限的应用场合意义重大。基于BLS短签名,利用椭圆曲线的双线性对技术提出了一个短代理多重签名方案,并在随机预言模型下证明该方案的不可伪造性和安全性。

| Abstract: | Proxy multi-signature is an extension of the basic proxy signature primitive,and permits two or more original singers to delegate their signing powers to the same proxy signer.It is great significant to shorten the length of the signature for a secure proxy signature scheme,especially for some applications where bandwidth is limited.Based on BLS short signature scheme,it constructs a short proxy multi-signature scheme by bilinear pairings on elliptic curve technology,and presents the proof of resisting forgery attack and security in the random oracle model. |

| Keywords: | proxy multi-signature bilinear pairings random oracle security proof |
