Abstract
Prosessor (400) for kryptering eller dekryptering av informasjon som skal kommuniseres fra et første sted til et andre sted, hvilken prosessor kan drives i i det minste én av to moduser, omfattende (i) en første modus hvor informasjon blir kryptert av en krypteringsdel av en nøkkelstrimmel og en synkroniseringsindikator blir generert i tilknytning til hver krypteringsdel, og (ii) en andre modus hvor informasjon blir kryptert av et flertall krypteringsdeler og en enkel synkroniseringsindikator blir generert i tilknytning til hvert flertall av krypteringsdeler. Det er også beskrevet en krypterings- og dekrypteringsprosessor som benytter prosessoren og fremgangsmåter som benytter prosessoren og krypterings- og dekrypteringsprosessoren. En sender og mottaker som benytter krypterings-/dekrypteringsprosessoren og en telekommunika-sjonsterminal, og en fremgangsmåte ved bruk av terminalen er også beskrevet.
