Abstract
En fremgangsmåte for å opprette trygg kommunikasjon mellom brukere ved hjelp av et krypterings/dekrypteringssystem med almen nøkkel omfatter et trinn hvor et senter (C) genererer et par nøkler innbefattet en almen nøkkel. En bruker (A) genererer et par nøkler som omfatter en almen nøkkel (Pa), men dens egen almene nøkkel krypteres med senterets almene nøkkel (PcKs). Brukeren (A) sender sin almene nøkkel (Pa) kryptert med senterets almene nøkkel (Pcks), til senteret, og senteret (C) dekrypterer den almene nøkkel tilhørende brukeren, og dersom brukeren er godkjent av senteret, sender senteret den almene nøkkel tilhørende denne bruker kryptert med seg selv, til vedkommende bruker. Denne fremgangsmåte gjør det mulig å oppnå sentralisert styring av brukernes almene nøkler.
