Most of the lightweight blo ck 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 Skip jack by quasigroup string transformations. For obtaining suitable representation we use the fact that Feistel round functions that are bijections can b e considered as orthomorphisms of groups, and that give us a to ol for creating wanted quasigroups. |
