Abstract

Most of the lightweight block ciphers are build as S-P networks or Feistel networks, their generalization or variations. We represent the lightweight Feistel ciphers GOST and MIBS, and Generalized Feistel cipher Skipjack by quasigroup string transformations. For obtaining suitable representation we use the fact that Feistel round functions that are bijections can be considered as orthomorphisms of groups, and that give us a tool for creating wanted quasigroups.
