摘要： 基于双线性对的代理签名将IBE(IdentityBasedEncryption)的优势得以体现的同时具有了代理签名的功能。移动代理是一个自主性的软件实体,它可以在不同的执行环境中执行,适用于窄带宽和非同步连接,移动用户可以授权移动代理在网上搜索适合的产品或服务。由于移动代理的这一特性,人们很早就将代理签名应用其中。但是由于PKI(PublicKeyInfrastructure)的一些局限性,使得移动代理的效率不高,该文应用基于身份加密的代理签名方案来解决这个问题。

Abstract: Proxy signature based on pairing has the advantage of IBE(identity based encryption).Mobile agent is an autonomy software that can be executed in various environments,such as low bandwidth or asynchrony.The mobile users can authorize mobile agent to search for the products or services in network automatically.Because of the property of mobile agent,people applied proxy signature in mobile agent for a long time,but lack of efficiency for the limitation of PKI( public key infrastructure).The purpose of this article is to solve this problem using the identity based proxy signature.
