摘要： Methods and apparatus for reducing the effectiveness of chosen location attacks in a peer-to-peer overlay network. A method includes determining that new node identifiers are to be generated for a plurality of nodes in the network, inputting parameters to a hash function to generate a selected node identifier, and adopting a location in the network associated with the selected node identifier. Another method includes receiving a node identifier associated with a selected node, inputting parameters associated with the selected node to a hash function to generate a corresponding node identifier, comparing the node identifier with the corresponding node identifier, and determining that the selected node is a potential attacker if the node identifiers do not match. Another method includes detecting responsibility for initiating an update to one or more node identifiers, generating parameters to generate the node identifiers, and transmitting the parameters on the network.

摘要： Methods and apparatus are described herein for performing AND/OR searching using multiple keywords. A query is received at a first node in a network having multiple keywords. The first node determines a set of documents matching a first of the multiple keywords, and computes an ideal Bloom filter representing those keywords. The first node sends the query and the Bloom filter to a second node, which determines its search results for a second of the multiple keywords in accordance with the Bloom filter.

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： 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： A method for using Internet mobility protocols with non Internet mobility- protocols, e.g., in a 3GPP or an SEA/LTE system, is described. A first gateway node comprising a home Agent (304) as well as a Legacy Gateway Node (LGN 302)m which may be a Gateway GPRS Support Node (GGSN), communicates with a second gateway node comprising a Local Mobility Agent (LMA 314) as well as a Legacy Serving Node (LSN 312), which may be a Servicing GPRS Support Node (SGSN), using a first protocol. The first protocol is a non Internet mobility protocol, e.g., the GPRS tunneling protocol GTP. A home address (HoA) for a mobile node is managed by the second gateway node. Updates regarding the location of the mobile node within a domain are received using a second protocol. The second protocol is an Internet mobility protocol, e.g., Mobile IP (MIP). Intra-domain mobility for the mobile node is managed by the second gateway node using the second protocol. To manage the local mobility the Local Mobility Agent (LMA 314) uses a local mobility protocol, e.g., Hierarchical Mobile IP (HMIP), Fast Mobile IP (FMIP), Proxy Mobile IP (PMIP), or Network-based Local Mobility Management (NETLMM).
