Abstract

Die Erfindung betrifft ein Verfahren für eine digital druckende Frankiermaschine und zur Erzeugung und Überprüfung eines Sicherheitsabdruckes, wobei wesentliche Frankierinformationen zusammen mit einer Signatur auf ein Poststück im maschinenlesbaren Bereich des Frankierbildes aufgedruckt werden. Für den Abdruck, der human lesbar und außerdem sicher maschinenlesbar ist, kann ein Druckkopf üblicher Druckbreite eingesetzt werden, weil durch ein modifiziertes Public Key-Verfahren die zu druckende maschinenlesbare Informationsmenge reduziert ist, weil der geheime Schreibschlüssel Kw und der Algorithmus zur Verschlüsselung auf der Frankiermaschinenseite in einem Sicherheitsgerät PSD gespeichert ist, sowie weil der öffentliche Leseschlüssel und sein Zertifikat der Frankiermaschinen-Kennung zugeordnet einer Datenbank auf der Postseite entnommen werden kann. Das für Frankiermaschinen modifizierte Public Key-Verfahren zeichnet sich durch eine einfache Schlüsselgenerierung und Verschlüsselung der Botschaft auf der Frankiermaschinenseite und eine einfache Entschlüsselung der Botschaft auf der Postseite aus.

Figure 00000001
The invention relates to a method for a digitally printing franking machine and for generating and checking a security imprint, wherein essential franking information is printed together with a signature on a piece of mail in the machine-readable area of the franking image. A print head of conventional print width can be used for the print, which is human-readable and also machine-readable, because the machine-readable amount of information to be printed is reduced by a modified public key process, because the secret write key Kw and the algorithm for encryption on the franking machine side is stored in a security device PSD, and because the public reading key and its certificate associated with the franking machine identifier can be found in a database on the mail side. The public key procedure modified for franking machines is characterized by simple key generation and encryption of the message on the franking machine side and simple decryption of the message on the mail side.
