Title:
Shorter Signatures from MQ
Authors: William Wang
Abstract:We describe a simple MPC protocol in the preprocessing model for computing multivariate quadratic maps. This yields Mesquite, a KKW-style signature scheme which, to our knowledge, produces the shortest signatures of any based on the MQ assumption. For example, our compact parameter set targeting NIST security level I has an average signature size of 8.8KB and runtimes on par with Picnic3 L1.
