Method and system for dynamic server document encryption

Abstract: A method and system are provided for secure document delivery over a wide area network, such as the Internet. A sender directs a Delivery Server to retrieve an intended recipient's public key. The Delivery Server dynamically queries a certificate authority and retrieves the public key. The public key is transmitted from the Delivery Server to the sender. The sender encrypts the document using a secret key and then encrypts the secret key using the public key. Both encrypted document and encrypted secret key are uploaded to the Delivery Server, and transmitted to the intended recipient. The intended recipient then uses the private key associated with the public key to decrypt the secret key, and uses the secret key to decrypt the document. In an alternative, equally preferred embodiment of the invention, the sender uses the public key to encrypt the document. In yet another embodiment, the server transmits the document to the Delivery Server for encryption.

Method and system for providing a networked collaborative work environment

Abstract: A system and method for providing a collaborative work environment includes servers and client workstations. Client workstations receive data objects from one or more servers and combine the received data objects with stored templates to render HTML pages representing at least a portion of a common project. Users may view, edit, and create common documents for the projects and upload them to the server using a drag-and-drop interface. Additionally, since all file transfers take place using HTTP, project groups can span corporate organizations as well as time zones and geographic boundaries.

Basic support for cooperative work on the World Wide Web

Abstract: The emergence and widespread adoption of the World Wide Web offers a great deal of potential in supporting cross-platform cooperative work within widely dispersed working groups. The Basic Support for Cooperative Work (BSCW) project at GMD is attempting to realize this potential through development of web-based tools which provide cross-platform collaboration services to groups using existing web technologies. This paper describes one of these tools, theBSCW Shared Workspace system?a centralized cooperative application integrated with an unmodified web server and accessible from standard web browsers. The BSCW system supports cooperation through “shared workspaces”; small repositories in which users can upload documents, hold threaded discussions and obtain information on the previous activities of other users to coordinate their own work. The current version of the system is described in detail, including design choices resulting from use of the web as a cooperation platform and feedback from users following the release of a previous version of BSCW to the public domain.

Securely downloading and executing code from mutually suspicious authorities

Abstract: An apparatus, system and method for secure code-downloading and information exchange, in the full generality of complex code dependencies while considering the implications of mutual distrust and hot-swapping. Included are secure techniques wherein an authority signs code from another party upon which that authority depends in order to establish that a trusted execution environment, is being preserved. Trusted code is employed to ensure that proprietary data is destroyed, disabled, and/or made unreadable, when a change causes the trusted execution environment to cease holding to a certain security level. A carefully constructed key structure is employed to ensure that communications allegedly from particular code in a particular environment can be authenticated as such. Authenticity of code that decides the authenticity of public-key signatures, and/or the authenticity of other code is cared for. In particular, the loading code that performs these tasks may itself be reloadable. Authenticity is maintained in physically secure coprocessors with multiple levels of dependent software that is independently downloadable by mutually suspicious authorities, and in physically secure coprocessors whose software has sufficient richness and complexity so as to be certainly permeable. Recoverability is provided for physically secure coprocessors from code of arbitrary evil running at arbitrary privilege.

Remote resource management system for automatically downloading required files from application server depending on contents of selected files on requesting computer

Abstract: A remote resource management system for maintaining resources shared in a distributed computing system, which downloads only such resources that are the most suitable for an application requested by a user. When a user selects an application at a terminal computer, an application server computer providing the selected application will determine the most suitable resources for the selected application by consulting a resource linkage manager disposed therein. The application server transfers information advising the suitable resources, together with a download agent, to the terminal computer. In the terminal computer, the download agent determines whether the resources should be newly downloaded or not, referring to local resource management information that describes what resources exist in the terminal computer. If downloading is necessary, the resource management system locates the necessary resource files by using a downloadable resource management directory in a resource server computer. The resource files are downloaded from downloadable resource storage in the resource server computer, and installed into the terminal computer system according to a specified installation mode. When the installation is finished, the download agent will be unloaded, and the application runs with the downloaded resources.

Method for automatically regenerating information at a client system in the event of power or communication disruption between the client system and the server

Abstract: A method and computer program product for automatically regenerating information at a client system without user intervention in the event of power disruption or disruption in communication between the client system and a server. A first communication session is established between the client system and the server. The status of the power connection of the client system is monitored as well as monitoring the status of the communication link between the client system and the server. If there is no disruption in the power connection or communication link at the client system, the server automatically downloads data blocks from the server for storage at the client system. On the other hand, if the power connection or communication link is disrupted, a sustaining device is enabled to ensure that writing of any current block of data from the server is completed, and thereafter, upon resuming power or the communication link at the client system, the server then resumes downloading of only those remaining data blocks from the server that had not been downloaded at the time of disruption.

Network server platform/facilities management platform caching server

Abstract: The location of large caches of memory located at the network server platform can reduce traffic on the network trunks or Internet backbone. In some instances these memory caches might be located at the facilities management platform. Those users supported on a specific network server platform no longer would be required to download regularly used information from the Internet backbone minimizing congestion on the network. These memory caches can be supplemented or refreshed with new data on a regular basis based on the requirements or changing requirements of the users. The close location of regularly accessed data allows for faster downloads and minimizes congestion on the communication network. In addition to user requested information, push information can be stored in these caches for fast downloading to the users.

System for providing enhanced grade of service for connections over a large network

Abstract: We have realized that for a connection over a large data network, such as an Internet connection that couples a web access device to a terminal server connected to an applications server, delays associated with the process of downloading large data files over such a connection, occur primarily in the leg of the connection that couples the applications server to a terminal server while little congestion is typically observed in the leg of the connection that couples the Internet access device to the terminal server. The aforementioned delay is reduced by establishing a separate connection from the applications server to the Point Of Presence server outside or independently of the backbone of the large data network thereby allowing users to receive enhanced grade of service for file transfer operations.
