Abstract

En tilgangskontrollmodul tillater en bruker med en forhåndstildelt passordfrase å få tilgang til krypterings- eller dekrypteringsdelen til et program ved å sammenligne en generert vektor eller nøkkel med en delvis dekryptert versjon av en annen vektor eller nøkkel lagret på et transportabelt lagringsmedium, som for eksempel en floppydisk. Dersom sammenligningen er vellykket, lager tilgangskontrollmodulen en hovednøkkel som deretter benyttes gjennom resten av programmet for å kryptere eller dekryptere merker. Deler av krypterings- og dekrypteringsprosessen benytter en intern, reproduserbar, men ikke reversibel omkastings-underrutine hvor bytene i en initialiseringsvektor suksessivt eksklu,iv-eller'es med hverandre, idet et inngangstall, kalt spinup- tall, kontrollerer hvor mange ganger prosessen gjentas.
