基于N-R签名体制的一种新的盲代理多重盲签名方案

A new blind proxy multiple blind signature scheme based on n-r signature system

在现实中,如果盲代理签名、多重签名、盲签名被同时需要,则要有一个盲代理多重盲签名的安全方案来满足实际需要。文章基于Nyberg-Rueppel签名体制提出了一个新的满足上述需要的盲代理多重盲签名方案,且在此方案中,有效的避免了孤悬因子和代理签名密钥不包含代理签名人的秘钥的缺陷,并对此方案的安全性进行了分析。

When blind proxy signature, multi signature and blind signature are needed simultaneously, a blind proxy multi blind signature scheme is needed to meet the actual needs. Based on the Nyberg-Rueppel signature scheme, a new blind proxy multiple blind signature scheme satisfying the above needs is designed. This scheme can effectively avoid the defects of suspending factor and the proxy signature key does not contain the proxy signer＇s secret key,and the security of the scheme is also analyzed.
