Abstract

En melding i plantekst, som skal kodes, deles inn i et antall ord, f.eks. fire ord som er lagret i registre A, B, C og D, og en heltallsmultiplikasjonsfunksjon (14,20) anvendes på en undergruppe av ordene, f.eks. på de to ordene i regist- rene B og D. Anvendelsen av en slik heltallsmultiplikasjonsfunksjon øker be- tydelig den spredningen som oppnås per krypteringsrunde, hvilket muliggjør en høyere sikkerhet per runde og et økt gjennomløp. Heltallsmultiplikasjonsfunk- sjonen (14,20) kan være en kvadratisk funksjon på formen f(x) = x (ax + b), hvor a er et partall og b er et oddetall, eller en annen hensiktsmessig funksjon så som et høyere ordens polynom. Resultatene fra heltallsmultiplikasjonsfunk- sjonen roteres (16,22) med lg w bit, hvor lg betegner logaritmen med base 2 og w er antallet bit i et gitt ord, for å generere et mellomresultat-par f og u. En eks- klusiv-OR (18) operasjon av et annet ord, f.eks. ordet i register A og ett av mel- lomresultatene, f.eks. r, roteres (26) en mengde bestemt av det andre mellom- resultatet u. Tilsvarende roteres (30) en eksklusiv-OR (24) av det gjenværende ordet i register D og mellomresultatet u en mengde bestemt av det andre mel- lomresultatet t. Et element i en liste (array) med hemmelige nøkler anvendes på hver av disse rotasjonsresultatene (28,32), og registerinnholdene er da trans- formert. Denne prosessen gjentas et bestemt antall runder for å generere en melding i chiffertekst. Forbehandlings- (10,12) og etterbehandlings- (34,36) operasjoner kan inkluderes for å sikre at inndataene eller utdataene ikke av- slører intern informasjon om noen av krypteringsrundene. Motsvarende de- krypteringsoperasjoner kan anvendes for å dekryptere chiffertekst-meldingen.
