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 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.
摘要翻译：提供了一种在封闭的系统邮资计费器中防止重放攻击的方法和系统。包括“新鲜度”数据以及从仪表发送到打印机的每个标记信息，从而使打印机能够检测“过时”标记数据，即先前产生和正在重播的标记数据，并禁止打印副本标记。新鲜度数据包括打印机在初始化期间产生的随机随机数以及打印机可以针对来自先前打印的标记的序列数据的序列数据。如果在当前的标记消息中，随机数不同，或者当前序列数据不大于或等于来自先前打印的标记的序列数据，表明当前标记数据可能已经被生成并且是重播，则打印机将不会打印当前的标记数据。

摘要： 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.

摘要： A method and system for printing a 2D-barcode corresponding to a binary data array and a substrate imprinted with such barcode. The barcode has I first columns of modules and J rows of modules transverse to columns. Each module having a one-to-one correspondence with a bit in a data array and comprising X columns and Y rows of pixels. All pixels are unprinted if said corresponding data bits for a module is not asserted; and otherwise: for pixel columns P(1) through P(X−H) and rows P(1) through P(Y−V), where H is in the range 0 to X−1 and V is in the range 0 to Y−1, all pixels are printed; for first columns P(X−H+1) through P(X) and rows P(1) through P(Y−V), all pixels are printed if a corresponding data bit for an adjacent module in the next module column is asserted; and for columns P(X−H+1) through P(X), rows P(Y−V+1) through P(Y) are not printed if a corresponding data bit for an adjacent or diagonally adjacent module in a next first is not asserted. H and V are not both equal to 0.

摘要： A method of printing a string of characters includes receiving a sequence of character data codes. Each character data code corresponds to a respective character to be printed in the string of characters. The method also includes transcoding the sequence of character data codes to generate a sequence of glyph codes. Each glyph code corresponds to a respective glyph. Each glyph corresponds to at least part of a respective character. At least some of the glyphs correspond to less than a complete character. The method further includes using the sequence of glyph codes to generate print image data and printing an image on the basis of the print image data.
