摘要： A novel key management approach is provided for securing communication handoffs between and access terminal and two access points. This approach provides for securely handing off communications between an access terminal and access point without risking exposure a master key for the access terminal. Temporary master keys are derived for low latency handoffs and secure authentication between a new access point and the access terminal. In one aspect, a distributive key management scheme is provided in which a current access point generates a new security key (based on its own security key) that is used by the next access point with which an access terminal communicates. In another aspect, a centralized key management scheme is provided in which a central authenticator maintains, generates, and distributes new security keys (based on a master security key associated with the access terminal) to access points.

摘要： Methods and apparatuses are provided for facilitating group access controls in peer-to-peer or other similar overlay networks. A group administrator may create a group in the overlay network and may assign peer-specific certificates to each member of the group for indicating membership in the group. A group member peer node can access data objects in the overlay network using its respective peer-specific certificate to authenticate itself as a group member. The authentication is performed by another peer node in the network. The validating peer node can authenticate that the group member is the rightful possessor of the peer-specific certificate using a public key associated with the peer node to which the peer-specific certificate was issued. The validating peer node can also validate that the peer-specific certificate was properly issued to the group member using a public key of the apparatus that issued the peer-specific certificate.

摘要： A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.

摘要： A method is provided for securing a PMIP tunnel between a serving gateway and a new access node through which an access terminal communicates. A PMIP key hierarchy unique to each access terminal is maintained by the gateway. The gateway uses a first node key to secure PMIP tunnels when authentication of the access terminal has been performed. A PMIP key is generated based on the first node key and the PMIP key is sent to the new access node to assist in establishing and securing a PMIP tunnel between the gateway and the new access node. Otherwise, when authentication of the access terminal has not been performed, the gateway generates a second node key and sends it to an intermediary network node which then generates and sends a PMIP key to the new access node. This second key is then used to secure the PMIP tunnel.

摘要： Systems and methods are described herein for updating documents in a distributed network. When a new document needs to be added to the network, or when changes are to be made to an existing document, keywords are extracted from the document and used to generate update messages for each keyword. The nodes responsible for each keyword are determined. The individual update messages are consolidated into a composite update messages that is sent to a first node in the network. The first node extracts those portions of the composite message associated with it, and forwards the composite message to a second node in the network.

摘要： Techniques are provided to infer a context associated with a mobile device based on aggregated data from a set of other mobile devices. The set of mobile devices can include mobile devices currently or previously near a location of the mobile device. Each mobile device in the set of other mobile devices can collect sensor data and infer a low-level context (e.g., “sitting” or “standing”). The low-level contexts can be aggregated. Based on the aggregated low-level contexts, a high-level context (e.g., “at a party” or “watching television”) associated with the mobile device can be inferred or a low-level context associated with the mobile device can be refined.

摘要： Techniques disclosed herein provide for assisted context determination through the use of one or more servers remote to a mobile device. The one or more servers can receive location and/or other information from the mobile device and select, from a list of possible activities, a smaller list of activities a mobile device user is likely engaged in. The one or more servers can return the smaller list to the mobile device, which can use the smaller list to make a faster context determination. In creating the smaller list, the one or more servers can utilize information regarding a region in which the mobile device is located, which can be updated and modified using information received from mobile devices. Furthermore, the one or more servers can gather and share information from nearby mobile devices, enabling a mobile device to use information from nearby mobile devices to facilitate a context determination.

摘要： A mobile platform efficiently processes sensor data, including image data, using distributed processing in which latency sensitive operations are performed on the mobile platform, while latency insensitive, but computationally intensive operations are performed on a remote server. The mobile platform acquires sensor data, such as image data, and determines whether there is a trigger event to transmit the sensor data to the server. The trigger event may be a change in the sensor data relative to previously acquired sensor data, e.g., a scene change in an image. When a change is present, the sensor data may be transmitted to the server for processing. The server processes the sensor data and returns information related to the sensor data, such as identification of an object in an image or a reference image or model. The mobile platform may then perform reference based tracking using the identified object or reference image or model.
