摘要： A method and system for securing the communication link between the accounting device and printer of a metering system by authenticating the data being sent via the link utilizing a Nonlinear Feedback Shift Register (NLFSR) based system is provided. A NLFSR is provided in each of the accounting unit and printing unit of a metering system. The NLFSR in the accounting unit is utilized to generate a message authentication code (MAC) for the image data being sent from the accounting unit to the printing unit. The printing unit generates a corresponding MAC for the received image data using the NLFSR in the printing unit. The MAC generated by the printing unit is compared with the MAC generated by the accounting unit. If the MACs are similar, the image data is accepted as authentic and the printing unit will print the image corresponding to the image data.

摘要： An apparatus for evidencing an occurrence of a transaction is provided that includes a tamper indicating housing, a processing unit provided within the tamper indicating housing, and a cryptographic module also provided within the tamper indicating housing. The processing unit is adapted to: (i) determine current location information indicating a current location of the apparatus, (ii) obtain transaction information relating to the transaction, and (iii) compile a data block including at least the current location information and the transaction information. The cryptographic module is adapted to generate cryptographic evidence based on the data block. The processing unit may also be adapted to obtain current time information, and the data block may further include the current time information. The processing unit may also be adapted to obtain user authentication information, such as biometric information, and the data block may further include the user authentication information.

摘要： Methods and systems for authenticating website users without exposing passwords or other sensitive information to potential theft are provided. When the user's computer connects to a website server all communications are routed through a secure authentication device. When the authentication device identifies the need for user information to be submitted to the website server, the application retrieves the required information from memory and inserts the information into the appropriate location in the website forms. Since the secure connection to the website server is established in the secure boundary of the authentication device, the information is protected from being obtained by any malware that may reside in the user's computer.

摘要： An image encryption method that includes receiving image data based on an image, wherein the image data comprises a plurality of pixel values, and permuting a plurality of, and preferably all of, the pixel values using at least a secret key to create permuted image data. Also, an image decryption method that includes scanning a printed image to create scanned image data. The printed image is generated from permuted image data that is generated by permuting a plurality of first pixel values of first image data using at least a secret key, obtaining a plurality of second pixel values from the scanned image data, and reverse-permuting a plurality of the second pixel values using at least the secret key to create reverse-permuted scanned image data.
