    摘要： 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.

    摘要： 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.

    摘要： A method of authenticating a PSD and an initializing infrastructure that uses a secret key, a PSD public/private key pair and a provider public/private key pair. The infrastructure prepares a signed provider key record using the provider public key and the provider private key and a first MAC using the signed provider key record and the secret key. Both are sent to the PSD. The PSD authenticates the signed provider key record using the first MAC and the provider public key using the included digital signature. The PSD prepares a signed PSD key record using the PSD public key and the PSD private key and a second MAC using the signed PSD key record and the secret key. Both are sent to the infrastructure. The infrastructure authenticates the signed PSD key record using the second MAC and the PSD public key using the included digital signature.

    摘要： A method and system that increases the throughput of a mailing machine by continuously computing indicia prior to and during mail processing is provided. The indicia generation process is divided into two distinct parts, cryptographic calculation and funds committal/printing. Indicium data are continuously computed, asynchronously with the printing of the indicia, and stored in a buffer until needed. This enables several indicium data to be computed and stored prior to processing of a mail piece by the mailing machine. Prior to printing an indicium on a mail piece, the funds for the indicium are accounted for by updating the registers of the mailing machine. Since a number of indicium data may be pre-computed prior to the start of processing the mail through the mailing machine, the throughput of the mailing machine can be increased.
