Digital signature scheme is an important research topic in cryptography.Proxy signature is a special digital signature.It allows a signer,called an original signer,to delegate his/her signing capability to another person,called a proxy signer,to create a signature on behalf of him/her when he/she cannot sign a message for some reason.Lee,et al.'s strong proxy signature scheme and proxy multi-signature scheme are reviewed.Sun,et al.'s analyze on strong unforgeability is mentioned.A modified strong proxy signature...

数字签名是密码学的重要问题之一 ;代理签名是一种特殊的数字签名 ,它是指当某个签名人 (原始签名人 )由于某种原因不能签名时 ,将签名权委托给他人 (代理签名人 )替自己行使签名权。回顾了Lee等人提出的强代理签名方案和代理多签名方案以及Sun等人提出对其强不可伪造性的分析。在强代理签名方案的基础上 ,提出了改进的强代理签名方案 ,该方案具有强不可伪造性 ,从而可以有效地防止原始签名人对代理签名人进行恶意攻击 ,并将其推广到代理多签名方案

在一个安全的代理签名方案中,只有指定的代理签名人能够代表原始签名人生成代理签名.基于椭圆曲线离散对数问题,纪家慧和李大兴提出了一个代理签名方案和一个代理多签名方案,陈泽雄等人给出了另外两个代理多签名方案.但是,在他们的方案中,原始签名人能够伪造代理签名私钥.为了抵抗原始签名人的伪造攻击,改进了代理签名密钥的生成过程,并对改进的方案进行了安全性分析.

An original signer may authorize a proxy signer who can sign a message on behalf of the original signer in the known schemes while the proxy signer can't continue to authorize the others.In some cases,the proxy signer needs to do it.So a multi-level proxy signature scheme based on ECC is proposed.In this scheme,the first-level proxy signer not only can be authorized by the original signer but also can continue to authorize others under the agreement.The new scheme can simply carry out and has more security.It's...

An original signer may authorize a proxy signer who can sign a message on behalf of the original signer in the known schemes while the proxy signer can't continue to authorize the others.In some cases,the proxy signer needs to do it.So a multi-level proxy signature scheme based on ECC is proposed.In this scheme,the first-level proxy signer not only can be authorized by the original signer but also can continue to authorize others under the agreement.The new scheme can simply carry out and has more security.It's the first kind of multi-level proxy signature scheme so far.Furthermore,on the base of the above scheme,a multi-level multi-proxy multi-signature scheme is proposed.It can be used in more fields and some known proxy signature schemes can be regarded as the cases of it.It also has the properties of efficiency,non-repudiation and security.

在已知的各种代理签名方案中,原始签名人和代理签名人只能进行一级代理。但在有些情形下,签名权利需要逐级向下代理,而已知的方案不能满足这种需要。本文基于椭圆曲线提出了一种多级代理签名方案。在该方案中,原始签名人不仅可授权1级代理签名人对消息进行签名,而且1级代理签名人可在许可范围内继续逐级授权。新方案具有实现简单且安全性高等特点,而且也是迄今为止第一类多级代理签名方案。另外,该文还在上述方案的基础上,提出了多级多代理多签名方案。它的适用范围更加广泛,已知的一些代理签名方案可看作它的特例。同时,它也满足有效性、不可否认性、安全性等性质。
