Title:
MQ Does Not Reduce to TUOV
Authors: Laura Maddison
Abstract:The submission of the Triangular Unbalanced Oil and Vinegar (TUOV) digital signature scheme to the NIST competition in 2023 claims that if the Multivariate Quadratic (MQ) problem (with suitable parameters) is hard, then the TUOV problem must also be hard. We show why the proof fails and why the claimed theorem cannot be true in general.
