Abstract: System and method for securely backing up and reliably retrieving vault data in a metering system that includes a host processor operatively coupled to a vault. Whenever a transaction is completed by the vault, the vault cryptographically signs the vault data, including ascending register, descending register and piece count and sends the cryptographically signed vault data to the host processor where it is stored in a data file assigned to the vault. Each storage of the cryptographically signed vault data is indexed to create a historical log of vault transactions. If the vault is lost or damaged so that vault data cannot be retrieved from the vault, the cryptographically signed vault data is retrieved from the host processor data file and verified.

Abstract: A system for providing items of value, charging the items to a smart card, and for recharging the smart card. The system includes a station for providing the items of value, which may be postal services, and debiting the cost of the items to a smart card; the smart card being charged with funds equivalent data. The station also communicates with a Data Center for recharging the smart card. Users of the system communicate with the data center to request recharge of a particular smart card and in response to an authorized request the data center generates an encrypted authorization message which includes an identification number, the amount of recharge requested, and control data which preferably includes a control sum formed by adding the amounts stored in a descending register, which stores the amount available on the smart card, and an ascending register which stores the total of the amounts by which the card has been charged since initialization. Thus, the authorization message may be used only once.

Abstract: A method for printing a postal indicia on a mailpiece includes moving a printing mechanism and the mailpiece relative to each other during a plurality of passes; and printing with the printing mechanism at least a corresponding portion of the postal indicia during each of the plurality of passes, each of the corresponding portions being in overlapped relationship to the other corresponding portions so that the combined effect of the corresponding overlapped portions is a postal indicia which is detectable by a facer/canceler machine as a valid postal indicia. Furthermore, during no more than one of the plurality of passes is its corresponding portion of the postal indicia detectable by the facer/canceler machine as the valid postal indicia. An apparatus incorporates the above method.

Abstract: A method and apparatus for generating cryptographic keys for a postal manifest and for synchronizing cryptographic keys for transmitting postal data securely on a communication link is presented. The techniques for generating a key and for synchronizing keys use the same apparatus but use slightly different data to create a cryptographic key.The postal data center maintains a unique set of data for each server station. Using this set of data along with a manifest sequence number (or communication transaction number) and the date, a cryptographic key is created. Each server station stores a fixed master key, KO, a permutation table, Pt, and ID, and GMT date. Using the manifest sequence number (or the communication transaction number) a row of the permutation table is altered and the master key KO is scrambled with the permutation table top get a new key K2. With K2, the date, server ID, and manifest sequence number (our communication transaction number) are encrypted.
