On the security of new vinegar-like variant of multivariate signature scheme

Yasufumi Hashimoto
Abstract

In IMACC 2015 and Inscrypt 2015, Zhang and Tan proposed new vinegar-like variants of multivariate signature schemes. While their aims were to enhance the security of broken schemes, the security is much less than expected. In this note, we describe how to recover a public key of the original scheme.
