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. In this paper, we investigate the possibility of using the multivariate gemss signature scheme as the building block of a ring signature scheme.
Here are the size of public key, secret key and signature in the implementation. The implementation does not optimize the size, so it explains the difference with theorical sizes. From a practical point of view, the main drawback of gemss is the size of the public-key. However, we mention that the generation of a (public-key,secret-key) remains rather e cient in gemss.

The signing time is quite high and the public keys are quite large; These properties may be … It can be noticed in a glance that gemss key size requirements are extremely large compared to the classical algorithms. This is indeed a drawback of this cryptosystem, although it has some quite … Unfortunately, like other multivariant methods, it produces a relatively large public key: 352,188 bytes (for 128 bit security) and 1,237,964 bytes (for 192-bit security).
