【摘要】 为了实现一个盲代理签名能够同时代表多个原始签名人签名,在对盲代理签名研究的基础上,首次提出了盲代理多重签名这一概念,该签名克服了一个盲代理签名只能代表一个原始签名人签名的局限性。此外,在Nyberg-Rueppel盲代理签名和代理多重签名2种体制研究的基础上,基于离散对数,分别提出了具有盲代理签名和代理多重签名双重性质的第一类盲代理多重签名方案和第二类盲代理多重签名方案,并对2方案的安全性进行了论证。更多还原

【Abstract】 To realize that a blind proxy signature could be on behalf of multiple original signers,a new kind of signature,blind proxy multi-signature,was presented based on study on blind proxy signature for the first time.The new kind of signature could overcome the limitation that a blind proxy signature could not be on behalf of more than one original signer.Besides,on base of discrete logarithm,a first class of blind proxy multi-signature scheme and a second class of blind proxy multi-signature scheme were proposed based on both Nyberg-Rueppel blind proxy signature scheme and proxy multi-signature scheme.They have the properties of two proxy signature schemes,and their security was demon-strated.更多还原
