Abstract: Network architecture supports hosting and content distribution on a global scale. The architecture allows a Content Provider to replicate and serve its most popular content at an unlimited number of points throughout the world. The inventive framework comprises a set of servers operating in a distributed manner. The actual content to be served is preferably supported on a set of hosting servers (sometimes referred to as ghost servers). This content comprises HTML page objects that, conventionally, are served from a Content Provider site. A base HTML document portion of a Web page is served from the Content Provider's site while one or more embedded objects for the page are served from the hosting servers, preferably, those hosting servers near the client machine. By serving the base HTML document from the Content Provider's site, the Content Provider maintains control over the content.

Abstract: A technique for generating, for a given message to be signed, an authentic cryptographic signature that can be authenticated, by a recipient of the signed message, as having originated from a signor of the message; and appropriately authenticating such a signature. Specifically, this technique, given a message, such as, e.g., a numerical product copy identifier (83, 93), forms an authentic signature (87, 97), based on public-key cryptosystem, through use of generator value selected from points on an elliptic curve over a finite field. The authentic signature is generated using the generator value in conjunction with three keys; namely, a public key, a private key and a secret key, and thus substantially increases the security associated with cryptographic signatures generated through a conventional two-key public-key cryptosystem. A unique product copy indicia can be formed by concatenating the identifier, for a given product copy, with its corresponding authentic signature. During subsequent user installation of that copy to a computer (200), the user enters the indicia when prompted by execution of an installation program which, in turn, privately authenticates the signature contained in the indicia in order to continue or prematurely terminate the installation.

Abstract: The present invention concerns fusion of Fc domains with biologically active peptides and a process for preparing pharmaceutical agents using biologically active peptides. In this invention, pharmacologically active compounds are prepared by a process comprising: a) selecting at least one peptide that modulates the activity of a protein of interest; and b) preparing a pharmacologic agent comprising an Fc domain covalently linked to at least one amino acid of the selected peptide. Linkage to the vehicle increases the half-life of the peptide, which otherwise would be quickly degraded in vivo. The preferred vehicle is an Fc domain. The peptide is preferably selected by phage display, E. coli display, ribosome display, RNA-peptide screening, or chemical-peptide screening.

Abstract: A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload offload mobile traffic it provides a platform for new communication services. A proxy switch includes signaling message handling logic for receiving signaling messages from the MSC and BS in accordance with said mobile signaling protocol. Message transmission logic issues messages to the MSC and BS. A FSN and a BSN are provided for communication with the MSC, and another FSN/BSN pair are provided for communication with the BS. Logic detects whether a received message is a change over order message (COO) from one of the MSC and BS, indicating a break in a first signaling link between the proxy switch and the one of the MSC and BS, and logic generates and sends a COA message to the one of the MSC and BS containing the BSN maintained by the switch for communication with the one of the MSC and BS. Fault emulation logic forces a break in a second signaling link between the proxy switch and the other of the MSC and BS, wherein the second signaling link is configured to correspond to the first signaling link, and generates and sends a new COO message to the other of the MSC and BS.
