Abstract

Abstract: In a proxy signature scheme，the entity can delegate signing capabilities to other participants so that they can sign on behalf of the entity.Proxy signature scheme is used in applications such as electronic business.There are few provable secure proxy signature schemes.In this paper，a new provably secure proxy signature scheme based on bilinear pairings is proposed，which is more efficient than that of the existing ones.

Key words: proxy signature, bilinear pairings, random oracle model, provable security

摘要： 代理签名是指签名授权人委托某人代理其签名，它在电子商务领域里有着广泛应用。目前已知的可证明安全的代理签名还很少。利用椭圆曲线上的双线性对，构造了一个新的代理签名方案，该方案在随机预言模型下是可证明安全的，而且其效率也优于已有文献。

关键词: 代理签名, 双线性对, 随机预言模型, 可证明安全
