Abstract
This chapter deals with the Hidden Field Equations (HFE) cryptosystem and its variants. We start by an introduction of the basic HFE cryptosystem and study its security against direct and rank attacks. Furthermore, we give an overview of the various HFE variants for encryption and digital signatures. In the area of encryption schemes we study here the IPHFE+ and the ZHFE schemes, while, in the area of signature schemes, we analyze the HFEv- signature scheme and its extension Gui, which produces the shortest signatures of all currently existing schemes.
