| 中文摘要: |
| 在代理签名方案中,代理签名人可以代表原始签名人生成签名.在有些情形,需要一个代理签名能够同时代表多个原始签名人,这就是代理多重签名.随着椭圆曲线密码体制的出现,其以密钥短、安全性高赢得了密码学者及其相关工作者的喜爱.对文献[1]进行研究,发现其不具备强不可伪造性,结合文献[2],提出了一种新的基于椭圆曲线的代理多重签名,不仅保持了原有签名的优越性,也克服了原文不满足强不可伪造性的缺点,同时具有了自己独特的优点:密钥长度短、安全性能高,实现了一个签名人可以同时代表多个原始签名人在文件上进行签名,具有一定的使用价值. |
| 英文摘要: |
| The proxy signer can produce a signature for original signer.In some cases,A proxy signer need to represent numbers of the original signers,which is the proxy multiple signature.With the development of elliptic curve cryptography,it wins the fancy of cryptography scholars and workers for its short key and safety.Having researched article[1],I found that it didn’t have non-forgery.My paper proposes a new proxy multiple signature,with the combination of the article[2].It keeps the advantage of original article and overcomes its disadvantage.Furthermore,it has unique advantage which is short key and high security.This paper can represent an original signer to produce a multiple signature,which has some value in use. |
