Originální abstrakt

In this paper we discuss two basic ways of TTM cryptosystem modifications. We suggest to add one more polynomial transformation into the coding process, and we discuss the properties of Frobenius automorphism as a possible tool to prevent the so-called Patarin attack. As TTM is based on polynomial automorphisms of finite field F, we also study automorphisms over specific fields, namely certain field extensions.
