Abstract

Ein Verfahren zur Erzeugung eines kryptographischen Schlüssels zur Durchführung eines Verfahrens zur Schlüsseleinigung für eine verschlüsselte digitale Kommunikation, wobei eine Endpunktadresse EA eines Kommunikationsgerätes A direkt oder indirekt durch Anwendung der inversen Funktion L-1 einer Einweg-Funktion L mit Falltür in einen Teil des kryptographischen Schlüssels umgewandelt und für die Schlüsseleinigung verwendet wird.
