An ID-based(k,t,n) Threshold Group Signature Scheme
Abstract：In order to improve the security and practicality of proxy blind signature,this paper introduces a blind-proxy blind signature scheme by adopting ID-based cryptography and secret sharing.In this scheme,the combination of proxy signature and blind signature can make the scheme has many characteristics,such as delegation of authority of proxy signature and the untraceability and anonymity of blind signature and so on.At the same time,blind the proxy signer make anyone can't know the identity of the proxy signers.Based on the identity cryptography,to introduce the secret sharing,will be good for solving the problem that the power of the proxy signers is too concentrated.SO this scheme has the better flexibility and higher security characteristics.
