一個(gè)帶簽名者意向的結(jié)構(gòu)化多重簽名方案
A Structured Multi-signature Scheme with Signers Intentions

摘要: 多重簽名是一種由多個(gè)簽名者同時(shí)協(xié)作完成對(duì)一個(gè)消息簽名的群體簽名形式。在多重簽名技術(shù)的應(yīng)用中，簽名方之間的簽名順序有可能需要滿足某一特定的要求，有時(shí)簽名者還要對(duì)消息簽署意見并供其后的簽名者參考?？紤]到這些應(yīng)用需求，該文提出了一個(gè)基于雙線性對(duì)的多重簽名方案，該方案具有預(yù)先設(shè)定簽名者之間的簽名次序和在簽名中加入簽名者各自意向的特性。安全分析表明它能抵抗各種內(nèi)部和外部攻擊，是一種安全的多重簽名方案。

Abstract: A multi-signature scheme is a digital signature scheme that allow multiple signers to generate in a collaborative and simultaneous manner. In the application of multi-signature, the signing order among co-signers may satisfy a special sequence and sometimes the each signer can express his intention associating with the message to be signed and referring by others. Considering the need of application, a multi-signature from bilinear pairings is proposed in this paper. The proposed scheme has two properties that it can set up the order of signing in advance and add the intention of signer into the signature. The security analysis of the new scheme shows that it can resist all kind of outsider and insider attacks. -
