摘要

基于身份的门限代理签名方案大都是在随机预言模型下进行安全证明

并且方案中每个代理人的代理签名密钥在有效期内都是固定不变的。在已有的基于身份的签名方案基础上

利用可公开验证秘密分享技术提出了一个在标准模型下可证安全的基于身份的(t

n)-动态门限代理签名方案。方案中代理人的代理签名密钥可以定期更新

而且代理签名验证过程只需要常数个双线性对运算

因此方案具有更好的动态安全性和较高的效率。

Abstract

The security of existing identity-based threshold proxy signature schemes were almost proven in the random oracle model

and each proxy signer’s proxy signature key was fixed in the valid period.A（t

n） ID-based proactive threshold proxy signature scheme（IBTPTS） was presented by using the publicly verifiable secret sharing technology

based on existential identity-based signature scheme.The scheme was proved to be safe in the standard model.Each proxy signer’s proxy signature key can be updated regularly

and proxy signature verifying procedure only needs const bi-linear pairings.Therefore the scheme has better dynamic security and higher efficiency.
