摘要
将门限签名的思想引入到混合代理多重签名中,提出了一种基于无证书的门限混合代理多重签名方案。该方案不仅允许部分原始签名者将签名权委托给相应的代理签名者,而且实现了只需达到一定数量的原始签名者和代理签名者一起合作即可完成签名。与普通的混合代理多重签名方案相比,具有更大的灵活性。进一步,对方案的正确性和安全性进行了分析。分析结果表明,提出的方案满足门限签名和混合代理多重签名所需的安全性要求。
This paper introduces a certificateless threshold hybrid proxy multi-signature scheme by applying the idea of threshold signature to hybrid proxy multi-signature.This new scheme not only allows some original signers to relegate their rights to sign to relevant proxy signers,but also makes a cooperative signature come true by obtaining a certain number of original signers and proxy signers.Compared with the ordinary hybrid proxy scheme,this new scheme has more flexibility.In addition,this paper analyzes the validity and security of this new scheme.The result shows that the proposed scheme satisfies the security requires needed in threshold signature scheme and hybrid proxy multi-signature scheme.
