A Tightly-Secure Lattice-Based Multisignature
Published: Jul 2, 2019
Abstract
Multisignatures enable multiple users to sign a message in an interactive manner. Many instantiations are proposed for multisignatures, however, most of them are quantum-insecure, because these are based on the integer factoring assumption or the discrete logarithm assumption. Although there exist some constructions based on the lattice problems, which are believed to be quantum-secure, their security reductions are loose. In this paper, we...
