摘要

这项工作提出了一个可证明安全的基于格子的多重签名方案，它只需要一轮通信，而现有的工作需要两到三轮。通过利用格子活板门来减少所提出方案的轮数。然而，为了安全地生成多重签名，我们的方案需要一个诚实的集中式服务器来维护方案中使用的共享矩阵的陷阱门。

Single-round Lattice-based Multisignatures

This work presents a provably-secure lattice-based multisignature scheme which requires only a single round of communication, whereas the existing works need two or three rounds. The reduction in the number of rounds for the proposed scheme is achieved by utilizing lattice trapdoors. In order to generate multisignatures securely, our scheme however requires an honest centralized server that maintains the trapdoor of a shared matrix used in the scheme.
