Abstract: An exemplary embodiment of a method (10) for authenticating software in a cable modem makes use of a secure key and certificate stored in flash memory. In this exemplary embodiment, the code employs a key to validate (16) a signature that is generated for each new build of the code. During build of the code, the code is digitally signed (12) using e.g., a Motorola RSA private key. The message digest and the signature are then stored at the end of code file itself (13). Each time the modem (52) reboots, the code can validate (16) that the image in flash has not been modified. This validation function (16) can be accomplished e.g., by calling an RSA Signature Verification function to confirm that the signature in the header equals the message digest signed by the manufacturer's private key or the manufacturer's CVC.

Abstract: Processing and packaging for perishable goods (436), such as beef, in a conduit (15514) wherein oxygen is substantially excluded and suitable gases such as carbon dioxide are provided at a suitable pressure and in such a manner as to increase the quantity of the gases dissolved in the perishable goods (436) to extend the shelf life of the goods and decontaminate the goods.
