摘要:
A system (10) and method of evidencing postage payment includes a data center (3) with a database (36) having a plurality of meter records (64) stored therein. Each meter record (64) includes meter information corresponding to a metering account assigned to each of a plurality of remote user devices (20, 22) that are authorized to request evidence of postage payment. When a request for postage (100) is received at the data center (30), a secure co-processor device (44) in the data center (3) obtains the appropriate meter record (64) and verifies the authenticity of the meter record (64) by verifying a signature (205, 210) in the meter record (64) and comparing freshness data (220, 225) in the meter record (64) to freshness data in the secure device (44). If verified, the secure device (44) then accounts for an amount of postage to be evidenced (130), generates evidence of postage payment (130) and updates the meter information, including the freshness data (130), in the meter record (64). The secure device (44) then signs the updated meter information and stores the signature in the meter record (64, 135, 140). The secure device (44) then returns the updated meter record (64) to the database (36, 135, 140).
摘要:
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.
摘要:
A method for controlling a postage metering system (1) defines a first set of postage parameters P1, P2, P3 to Pn associated with the generation of postage evidence in a postage metering system (10) and then initializes the postage metering system (10) with a subset of the first set of postage parameters F1, F2, F3 to Fn. The subset F1, F2, F3 to Fn defines a combination of the postage parameters for which the generation of postage evidence is not authorized. When a request for postage evidence is received, the request includes a second set of postage parameters P1, P2, P3 to Pn that are combined to form a postage parameter vector (PPV). The generation of postage evidence is inhibited when at least one of the postage parameters P1, P2, P3 to Pn in the second set matches one of the postage parameters in the first set F1, F2, F3 to Fn. When none of the postage parameters P1, P2, P3 to Pn in the second set matches one of the postage parameters in the first set F1, F2, F3 to Fn the requested postage evidence is generated. In an alternative method the subset defines a combination of the postage parameters for which the generation of postage evidence is authorized, and the requested postage evidence is generated when each of the postage parameters in the first set matches one of the postage parameters in the second set.
摘要:
A system (10, 20, 30) and method for selecting appropriate postal rates (110, 115, 120) when evidencing postage payment provides new postal rates to a computer (20) responsible for rating mail and provides a date when the new postal rates (110, 115, 120) become effective. The new postal rates (110, 115, 120) and the effective date are stored in the computer (20). When postage evidencing occurs, a selection (215, 220, 225, 230, 240) is made between the current postal rates stored in the computer (20) and the new postal rates for use in evidencing postage payment on a mail piece. The selection is based on the date the mail piece will be submitted for mailing (205, 225, 230, 240).
摘要:
A system and method is provided for refilling a postage metering system (100) that includes a host (114) coupled to a postal security device (PSD) (112). A user enters a first request for postage refill which is transmitted to a meter server (120). The meter server (120) transmits a request for a PSD audit to the postage metering system (100). PSD audit data is signed with a first secret key stored in the PSD (112) to produce an audit message that includes a first signature and the PSD audit data. The audit message is transmitted to the meter server (120) which transmits the first signature to a key management system (130) which then verifies the first signature using a second secret key stored in the key management system (130). A refill message includes a second signature and a refill combination. The refill message is transmitted to the PSD (112) which verifies the signature and the refill combination using the first secret key and credits the PSD (112) for the amount.
摘要:
A method for transmitting a key from a first device to a remotely located second device includes the steps of generating the key within the first device; selecting one of a plurality of one-time pad values from a one-time pad stored within the first device; creating a hash of at least the key and the selected one of the plurality of one-time pad values; and sending the hash and the key from the first device to the second device.
摘要:
Die Erfindung betrifft ein Verfahren zur Verbesserung der Sicherheit von Frankiermaschinen, mit einem Mikroprozessor (µP) in einer Steuereinrichtung (6) der Frankiermaschine zur Ausführung von Schritten für eine Start- und Initialisierungsroutine und nachfolgender Systemroutine, in der Programmroutinen abgearbeitet werden. Während der Ausführung einer Programmroutine erfolgt ein Verändern eines Zählwertes und Vergleich des vorgenannten Zählwertes mit mindestens einem vorbestimmten Zählwert nach Ausführung der Programmroutine. In einem einfachsten Fall wird ein Zählwert durch Inkrementieren mit einem dem ausgeführten Programmteil zugeordneten Wert verändert.
