    摘要： A method is provided for establishing mutual authentication and secure communications between a microprocessor-based transaction evidencing device (100) and a microprocessor-based server (120) coupled thereto. A session key K S is generated at the transaction evidencing device (100) and encrypted with a first key K 1 to form a first message. The first message is sent to the server (120) and decrypted using a second key K 2 . In response to the first message a second message is generated at the server (120) and encrypted using the session key K S . The encrypted second message is sent to the transaction evidencing device (100) and decrypted using the session key K S . A response to the second message is generated at the transaction evidencing device (100) and is signed using a third key K 3 . The signed response is encrypted with the session key K S and transmitted to the server (120). The encrypted signed response is decrypted using the session key K S and the signature is verified using a fourth key K 4 .

    摘要： A method for improving print quality for a 2-D bar code includes determining (305) printer type, including print resolution, for a printer that will print 2-D bar code and entering (315) paper type for the envelope. A suggested 2-D bar code module size is calculated (320) based on the paper and the printer type. A test sample 2-D bar code is printed (320) at the suggested 2-D bar code module size. The printed test sample is scanned (335) and then evaluated (340) for print quality and readability. The method can also suggest (350, 325) a 2-D bar code module size to the user.

    摘要： A system and method for efficient uncorrectable error detection in flash memory is described. A microcontroller including a non-volatile flash memory utilizes an Error Correction Code (ECC) having a certain error detection and correction bit strength. The user data is first processed by a hash function and hash data is stored with the user data. Then, the user data and hash data are processed by the ECC system. In detection, the hash ensures that a relatively low bit-strength ECC system did not incorrectly manipulate the user data. Such a hash integrity check provides an efficient, robust detection of incorrectly corrected user data resulting from errors beyond the correction but strength of the ECC system utilized.

    摘要： A method for removing postal funds from a postage meter (10) provides an accounting unit (20) of a postage meter (10) with indicium-related information which is invalid for mailing. The accounting unit (20) generates a digital signature, which is an encrypted value of the postal funds removed from the postage meter (10) and other postal data including the indicium-related information. The accounting unit (20) through a Host PC (12) sends to a data center (5) the amount of the postal funds removed from the postage meter (10) and the digital signature. The data center (5) verifies that the digital signature has been generated using the indicium-related information. The meter (10) is disabled when the digital signature cannot be verified. When the digital signature is verified a request for a refund is sent by the data center (5) to a postal authority. An example of the indicium-related information is an invalid destination postal code or an invalid origination postal code.
