论文摘要
数字签名是区块链平台上交易的主要组成部分，尤其是在企业区块链平台中，其中需要产生一组同行的多个签名来认可交易。但是，这种过程通常很复杂且耗时。多签名可以通过与一组签名者合作生成联合签名来提高交易效率，引起了广泛的关注。在这项工作中，我们提出了两个多签名方案，GMS和AGM，这些方案比最新的多签名方案更安全，更有效。此外，我们在真实的企业区块链平台Fabric中实现了所提出的方案。实验结果表明，提出的AGMS方案有助于实现高交易效率，低存储复杂性以及针对Rogue-key攻击和K-SUM问题攻击的高鲁棒性的目标。
Digital signature is a major component of transactions on Blockchain platforms, especially in enterprise Blockchain platforms, where multiple signatures from a set of peers need to be produced to endorse a transaction. However, such process is often complex and time-consuming. Multi-signature, which can improve transaction efficiency by having a set of signers cooperate to produce a joint signature, has attracted extensive attentions. In this work, we propose two multi-signature schemes, GMS and AGMS, which are proved to be more secure and efficient than state-of-the-art multi-signature schemes. Besides, we implement the proposed schemes in a real Enterprise Blockchain platform, Fabric. Experiment results show that the proposed AGMS scheme helps achieve the goal of high transaction efficiency, low storage complexity, as well as high robustness against rogue-key attacks and k-sum problem attacks.
