On the modifier Q for multivariate signature schemes

Yasufumi Hashimoto

Abstract

At PQCrypto 2021, Smith-Tone proposed a new modifier, called ``Q'', to construct a fast multivariate signature scheme from a known scheme. In the present paper, we propose an idea to weaken the security of this modifier.
