Abstract

I et kommunikasjonssystem hvor to kommunikasjonsenheter søker å etablere en privat eller konfidensiell kommunikasjonssesjon må først et forhold etableres mellom dem, særlig et forhold som må betegnes lukket og som er til å stole på. Dette forhold baseres på bestemmelsen av en delt hemmelighet som på sin side frembringes ved hjelp av sammenhengsinformasjon. Denne informasjon kan utledes fra de omstendigheter som omslutter kommunikasjonssesjonen. Som et eksempel kan sammenhengsinformasjonen innbefatte topologisk informasjon, tidsbasert informasjon og transaksjonsinformasjon. Den delte hemmelighet kan være selvgenerert eller mottatt fra en tredje part. I begge tilfeller kan den delte hemmelighet brukes som nøkkelmateriale for enhver kryptografisk protokoll som brukes mellom kommunikasjons-enhetene.
