| 摘 要： | 混合代理多重签名要求所有签名人共同产生签名，使方案的灵活性和实用性受限。针对该问题，通过引入门限签名，提出一个 (t, n)门限混合代理多重签名方案，在n个签名人组成的签名群中，只需t个或t个以上的签名人同意就可以完成签名。理论分析结果表明，该方案满足不可伪造性、不可否认性、可鉴别性、混合代理多重签名性和门限签名性，且效率高于原方案。

| Abstract: | Flexibility and practicability of hybrid proxy multi-signature are restricted bythe property that all of the signers produce signature together.In order to solve the problem,this paper proposes a(t,n) Threshold Hybrid Proxy Multi-signature(THPM) scheme combing with the threshold signature.A THPM is collaboratively generated by some original signers and some proxy signers on behalf of their original signers in the scheme.Only when t or more than t signers agree,the threshold number group members can produce a valid THPM in the signing group.Theoretical analysis proves that THPM not only has unforgeability,nonrepudiablity,distinguishability and quality of hybrid proxy multi-signature and threshold signature,but also is more efficient than original scheme. |
