A new identity-based proxy multiple blind signature scheme
Proxy signature is a solution to the delegation of signature rights.Proxy signature could combine with other special signature schemes to generate some new proxy signature schemes.Proxy multi-signature could solve the problem of one signer signing instead of multiple original signers,and blind signature is used to hide the original message.Combining the characteristics of proxy multi-signature and blind signature,an identity-based proxy multiple blind signature scheme was proposed from the perspective of bilinear pairing.The private key generator use each signer's identity to generate different keys.Through the security analysis of the scheme,it was found that the scheme could resist the internal attacks of the original signer and prevent the abuse of proxy signature rights.It had the characteristics of unforgeability,nonrepudiation,nonlinkability,blindness and high computing efficiency.
