  • Publication number: 20110265174
    Abstract: One embodiment of the present invention provides a system for facilitating session migration. During operation, the system receives a communication packet from a client destined to a remote server. The system determines whether the communication packet belongs to a pre-existing communication session, and whether session state information associated with the session is available locally. In response to the communication packet belonging to a pre-existing communication session and the session state information being unavailable locally, the system constructs an interest requesting the session state information, disseminates the interest over a network, and receives the session state information.

  • Patent number: 8023654
    Abstract: A method for securing human to human communication over a network includes receiving, by a first computer, an incoming authenticated data stream from a second computer over a first communication channel, the incoming authenticated data stream having been computed using an incoming digital experiential data stream and a first imprint, and extracting the first imprint from the incoming authenticated data stream. The incoming authenticated data stream is then presented for sensory experience by a human. An outgoing digital experiential data stream is then input and the method computes a second imprint associated with the first computer and computes an outgoing authenticated data stream using the outgoing digital experiential data stream and the second imprint. A second communication channel is then secured from the first computer to the second computer using the first imprint, the second communication channel suitable for sending the outgoing authenticated data stream to the second computer.

  • Publication number: 20110196896
    Abstract: A system is provided to facilitate tag-based organization of documents. During operation, the system receives an original user query. The system extends the query to include documents with an IN-tag and exclude documents with an OUT-tag. The system then performs a search based on the extended query to indicate a collection of documents which satisfy the extended query. The system further allows a user to add a document to the collection of documents or remove a document from the collection of documents. Next, the system modifies a tagging property of the document.

  • Publication number: 20110087882
    Abstract: Apparatus and methods are provided for protecting network resources, particularly in association with automatic provisioning of new client devices. A global PKI (Public Key Infrastructure) scheme is rooted at a globally available server. Roots of PKIs for individual organizations also reside at this server or another globally available resource. To enable access to an organization's network, one or more authenticators are deployed, which may be co-located with access points or other network components. After a client device enabler (CDE) and an authenticator perform mutual authentication with certificates issued within the global PKI, the CDE is used to provision a new client device for the organization. After the client is provisioned, it and an authenticator use certificates issued within the per-organization PKI to allow the client access to the network.

  • Patent number: 7916861
    Abstract: A method for establishing a secondary communication channel between at least two computing devices over a network medium through use of a primary channel connects a first computing device with a first telephonic unit and a second computing device with a second telephonic unit. If the two telephonic units are in communication with each other over a primary channel, and communication channels are established between the computing devices and their respective telephonic units, then the first computing device transmits its location information to the second computing device over the primary channel. A connection is then established between the second computing device and the first computing device over a secondary communication channel.

  • Publication number: 20100332977
    Abstract: One embodiment provides a system to facilitate directed reading of a selected portion of an original document by a recipient. During operation, the system creates a transfer document based at least on the original document and the selected portion. The transfer document, when viewed by the recipient, enables the following operations: opening the transfer document to the selected portion without requiring manual navigation to the selected portion, highlighting the selected portion, obscuring a context surrounding the selected portion based at least on a distance metric from the selected portion, and directly navigating from one highlighted portion to another highlighted portion in the transfer document without requiring manual navigation within obscured contexts. After the system creates the transfer document, it sends the transfer document to the recipient.

  • Patent number: 7822863
    Abstract: A method of accessing a data resource identifies the data resource, the data resource accessible through a first device and associated with a resource locator, the first device configured to provide access to the data resource responsive to possession of a whitelisted credential. The method includes receiving a second-device credential from a second device by a personal domain controller, the personal domain controller and the first device within a first trusted relationship and provides, by the personal domain controller, the second-device credential to the first device for whitelisting subject to the first trusted relationship. The method uses, by the second device, the second-device credential to access the data resource responsive to the resource locator.

  • Publication number: 20090285209
    Abstract: A system for facilitating voice calls over a content centric network (CCN) receives from a CCN user an expressed interest in receiving voice calls directed to the CCN user, wherein information in the CCN can be addressed, located, and disseminated by its content identifier and wherein data packets in the CCN are self-authenticating. Next, the system receives from a second network a packet for a voice call directed to the CCN user. The system then forwards to the CCN user the packet received from the second network with a CCN identifier corresponding to the interest expressed by the CCN user and forwards a packet from the CCN user for the voice call to the second network.

  • Publication number: 20090288163
    Abstract: One embodiment of the present invention provides a system for controlling the spread of interests and content in a content centric network (CCN). During operation, the system maintains a routing policy for content data. The system also receives a packet associated with a piece of content or an interest for the content. Next, the system determines that the structured name included in the packet is within the namespace specified in the routing policy. The system further determines that the packet satisfies the condition in the routing policy. Subsequently, the system routes the packet based on in part the action corresponding to the condition as specified in the routing policy.
