A mailing machine that optimizes throughput by reducing the amount of time necessary for the PSD to generate the digital signature and indicium for each mail piece is provided. The debit operation performed by the PSD, i.e., adjusting the PSD registers, is separated into three different sections, a pre-debit operation, a perform debit operation, and a complete debit operation. In addition, the calculation of the digital signature can optionally be pre-computed, or, alternatively, computed in stages, i.e., partial signature calculation. Utilizing this granularity, the cryptographic operations associated with generating the digital signature can be shifted between the three debit operations such that the execution time of the time critical portion of the debit operation (perform debit) can be optimized to meet the performance requirements of the mailing machine in which the PSD is deployed.

Method and system for optimizing throughput of mailing machines

A method and a system for collecting, segregating, and transmitting data relating to the use of a value metering system are described. A system and a method for dynamically updating collection, segregation, and/or transmission rules are also described.

Method and apparatus for transferring post meter data

A method and system that protects against a replay attack in a closed system postage meter is provided. 'Freshness' data is included along with each indicium message sent from the meter to the printer, thereby enabling the printer to detect 'stale' indicium data, i.e., indicium data that was previously generated and is being replayed, and prohibit the printing of duplicate indicia. The freshness data includes a random nonce generated by the printer during initialization along with sequence data that the printer can verify against sequence data from the previous printed indicium. If in the current indicium message the nonce is different or the current sequence data is not greater than or equal to the sequence data from the previous printed indicium, indicating the current indicium data may have been previously generated and is a replay, the printer will not print the current indicium data.

In a value dispensing system, a system and method for securely loading and executing software in a secure device that does not include any non-volatile programmable memory is provided. A non-secure portion of the value dispensing system stores software for loading into the secure portion when needed. Commands being sent to the secure printer are monitored to determine if the secure has the necessary software to execute the command. If the secure device currently does not have the necessary software to execute the command, the command is delayed and the proper software is loaded from the non-secure portion to the RAM of the secure device. A signature associated with the software is verified to ensure the authenticity of the software. If the signature is verified, the command is passed to the secure device, and, utilizing the software in the RAM, the command is executed by the secure device.

Method for securely loading and executing software in a secure device that cannot retain software after a loss of power

A postage metering system includes a base and a user interface mounted to the base. The user interface includes a micro controller, an internal socket for receiving an integrated circuit chip and a smart card reader interface connector for interfacing with an external smart card. The micro controller is configurable to address either the internal socket or the smart card reader interface connector to access postage metering functionality.

Postage metering system having multiple postage meter configuration capability

A method and device for improving the efficiency of a postage meter by using a sensing to detect the edges of an incoming envelope in order to initiate a multi-speed profile for transporting the envelope with different speeds through the postage meter. With the multi-speed profile, the postage meter is allowed to have sufficient time to process mail related data and provide mail related data to a print head before the envelope reaches a print zone where the print head starts printing an indicia on the envelope.

Method and device for improving the efficiency of a postage meter

A postage metering system includes a printer and a postage meter. The postage meter includes a micro controller for generating token data for use in printing a postal indicia where the token data includes an indicator of a token currency type. The printer is in communication with the postage meter and includes a micro controller, a memory and a print mechanism for printing the postal indicia on a mailpiece. The printer memory has stored therein indicia graphic data including an indicator of an indicia graphic currency type. The printer micro controller receives the token data from the postage meter and compares the token data indicator of the token currency type with the indicia graphic data indicator of the indicia graphic currency type prior to printing the postal indicia.

Postage metering system having currency synchronization

A postage metering system includes a postage meter and a user interface in communication with the postage meter. The user interface includes a micro controller and a memory. The memory has stored therein a plurality of image data files corresponding to different currencies. The postage meter includes a micro controller and a memory having stored therein an indicator of meter currency type. The user interface uses the indicator of meter currency type from the postage meter to select a particular one of the plurality of image data files for use in printing a postal indicia.
