摘要/Abstract

摘要： 代理签名方案中的密钥泄露问题在所难免。为了减轻代理签名方案中的密钥泄露带来的危害，将密钥隔离机制引入代理签名方案。现有的密钥隔离代理签名方案都是基于身份的。本文提出标准模型下的密钥隔离代理签名方案，并在安全模型中证明密钥隔离安全性和代理签名的不可伪造性。

Abstract: Keyexposure seems inevitable in proxy signature scheme. To minimize the damage caused by key exposure in proxy signature scheme， keyinsulated mechanism to proxy signature scheme was introduced. However， existing keyinsulated proxy signature schemes are based on identity. In this paper， we present a keyinsulated proxy signature scheme in the standard model. The scheme is keyinsulated security and unforgeability of the proxy signature.

Key words: keyinsulated, proxy signature, standard model
