The apparatus comprises: a first module including a universal key; a second module including a unique identifier and a unique key wherein the unique key is derived from the unique identifier and the universal key and incorporated into the second module during manufacture of the second module. The second module is in communication with the first module. The apparatus further comprises a controller for performing the following subsequent to manufacture of the first module and the second module: initiating a communication session between the first module and the second module; transmitting the unique identifier from the second module to the first module; and deriving the unique key in the first module using the unique identifier and the universal key. A method for synchronization of cryptographic keys between modules of a distributed system and a method of manufacturing a postage evidencing system are also provided.

A postage evidencing system including a plurality of domains for partitioning a population of postage meters according to an operating characteristic, a data center, a postage meter in operative communication with the data center and a printer in operative communication with the postage meter. The postage meter is initialized to operate in a particular domain while the printer is capable of operating in each of the plurality of domains. To update or enable a domain in the printer, the postage meter transmits an indication of the particular domain to the data center. Then, the data center encrypts the indication and transmits the indication to the postage meter which in turn forwards the encrypted indication to the printer. The printer decrypts the encrypted indication and using the indication enables a respective domain in the printer corresponding to the particular domain of the postage meter. A method for updating domains in a postage evidencing system is also provided.

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.

A mailing machine that includes a docking system for the User Interface Controller (UIC) that provides a safety interlock to protect the user from accessing potentially hazardous voltages when the UIC is removed is provided. A docking board provides a connection between the mailing machine and the UIC. The UIC mates with a docking connector on the docking board. Potentially hazardous signal levels pass through a relay on the docking board to the docking connector. A supply voltage for the relay's coil passes through docking board to the UIC and back to the relay on the docking board. If the UIC is removed, the supply voltage for the relay's coil will be removed, causing the relay to open and preventing any of the potentially hazardous signals from being transmitted to the docking connector on the docking board.

A mailing system is includes of a mailing machine operating under the control of a microcontroller having a communication port with a first channel and a second channel. The mailing system also includes a meter vault which operates under the control a microcontroller mounted in a secure housing and having a communication port with a first channel and a second channel. A printer is included which operates under the control of a microcontroller mounted in a secure housing and having a communication port having a first channel and a second channel. A printer interface is included for providing a number of independent communication paths. A first path provides communication between first channel of the mailing machine and the first channel of the meter vault. A second path provides communication between the second channel of the mailing machine and the second channel of the printer, and a third path for providing communications between the second channel of meter vault and the first channel of the printer.

A system for generating direct offers includes a computer system adapted to generate a group of offers, a list of targeted recipients that may be potential customers, and a set of business rules for selecting appropriate ones of the offers based at least in part on certain personal recipient information. The system also includes a third party computer system and a database that stores in confidence personal information for each of the targeted recipients. The third party computer system is adapted to receive the offers, the list of targeted recipients, and the set of business rules, select an appropriate one of the offers, if any, for each targeted recipient according to the business rules based at least in part on the personal information of the targeted recipients, and construct and cause to be sent a final offer for each of the targeted recipients for which an offer has been selected.

A mailing system includes a mailing machine having a printing mechanism for printing an indication of postage value on a mailpiece and structure for controlling relative movement between the printing mechanism and the mailpiece to ensure the mailpiece is properly positioned relative to the printing mechanism during printing of the indication of postage value; a meter vault having a securely sealed housing, and apparatus, within the securely sealed housing, for accounting for the printed indication of postage value, wherein the meter vault is removably mounted in the mailing machine for easy removal via a plug-in connector; and a printing mechanism control module for securely controlling printing by the printing mechanism based on data received from the meter vault, the printing mechanism control module being removably mounted in the mailing machine for easy removal via a quick disconnect connector; wherein the meter vault and the printing mechanism control module are in electrical communication via the mailing machine. The mailing system can also include ciphered communications between the vault and the printing mechanism.

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.
