In this paper, we study and construct multivariate schemes with \ultra-short signatures. We focus on the classic case where the public key is a set of multivariate polynomials of degree 2. Here are the size of public key, secret key and signature in the implementation.

We use a public-key format allowing to pack the bits of the public-key, while maintaining a fast use during the verifying process. On one hand, we save up to 18% of the public-key size. Overview gemss : A great multivariate short signature a. Casanova, j. -c. Faugère, g. Macario-rat, j.
