Abstract
The invention relates to a method for providing postal items with postal prepayment impressions, characterized in that data are generated in the customer system that are encrypted in such a manner that the value transfer center is able to decrypt them. To this end, the data are transmitted from the customer system to the value transfer center. The value transfer center then decrypts the data and re-encrypts them with a code not known to the customer system and transmits the encrypted data to the customer system
Claims35
A method for providing mailpieces with postage indicia, whereby a customer system loads a monetary amount from a value transfer center via a data line, whereby the customer system controls the printing of postage indicia onto mailpieces and whereby the value transfer center transmits a data packet to the customer system, characterized in that data is generated in the customer system and encrypted in such a manner that the value transfer center is able to decrypt this data, in that the data is transmitted from the customer system to the value transfer center and in that the value transfer center decrypts the data and then re-encrypts the data with a key not known to the customer system and subsequently transmits the data thus encrypted to the customer system.
The method according to one or more of the preceding claims, characterized in that the customer system signs the data with a private key.
The method according to one or more of the preceding claims, characterized in that the data is transmitted from the customer system to the value transfer center at the time of each request for a monetary amount.
The method according to one or more of the preceding claims, characterized in that the value transfer center identifies the customer system on the basis of the transmitted data.
The method according to one or more of the preceding claims, characterized in that the value transfer center transmits the data it has encrypted to the customer system.
The method according to one or more of the preceding claims, characterized in that, in each data transmission from the value transfer center to the customer system, an amount is transmitted that is sufficient to create several postage indicia.
The method according to one or more of the preceding claims, characterized in that a hash value is formed in the customer system.
The method according to one or more of the preceding claims, characterized in that the postage indicium contains logical data.
The method according to one or more of the preceding claims, characterized in that the postage indicium contains information transmitted by the value transfer center as well as data entered by the document producer.
The method according to one or more of the preceding claims, characterized in that the postage indicium contains a hash value that formed is on the basis of a combination of a value transmitted by the specification center and of a value entered by the document producer.
The method according to one or more of the preceding claims, characterized in that it comprises the following process steps:
- in the customer system or in a security module connected to the customer system a secret is generated and subsequently transmitted to the value transfer center, together with information about the identity of the document producer and/or of the customer system he/she is using.
The method according to one or more of the preceding claims, characterized in that the validity of postage indicia is verified in the mail center.
A customer system for franking mailpieces, characterized in that it comprises means for the encryption of data, in that it comprises a data output in order to transmit the encrypted data to a value transfer center and in that it comprises a data input for receiving data that has been differently encrypted by the value transfer center and in that the security module is configured in such a way that it cannot completely decrypt the data received from the value transfer center.
