Threshold Hybrid Proxy Multi-signature Scheme
摘要
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 / 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.关键词
