一种新的有代理的多重签名方案

随着对数字签名的研究和应用的不断深入,人们相继提出了多重签名、代理签名,后来又提出了多重代理签名、代理多重签名等。在这里将提出一种新的有代理的多重签名方案。在这种方案中,多个原始签名人将分别对自己选定的可信任的代理签名人进行代理授权,在签名过程中,N个签名人,可根据实际情况,允许有N′个原始签名人和N-N′个代理签名人共同参与。在签名认证中,验证人能验证签名者身份,即签名为原始签名人还是其代理签名人所签。

New Multi-signature Scheme with Proxy

With the deepening research and application of digital signatures,multi-signature and proxy signature have been introduced in succession.Later multi-proxy signature,proxy multi-signature,etc have been posed.Here we will put forward a new kind of proxy multi-signature,in which several original signers authorize their self-fixed credible proxy signers respectively.In the process of signature,N signers allow N′original ones and N-N′proxy ones to take part in together according to the actual situation.When testing and verifying the signature,the verifier can determine the identity of the signer.That is,he can tell whether the signature has been signed by the original signer or the proxy one.
