摘要： Storage authorization and access control of data stored on a peer-to-peer overlay network is provided. A publishing node (502) stores data on a storage node (506) in the overlay network. The publishing node (502) is adapted to facilitate data storage authorization by generating a resource identifier (516) as a function of a usage string associated with a data type' to be stored. A storage request (504) is generated that includes the resource identifier (516) and data to be stored (518). The storage request may be sent to the storage node (506). The storage device (506) receives the storage request (504) sent by a publishing node (502), including a resource identifier (516) and data to be stored (518). Independent storage authorization is performed by the storage node (506) at an overlay level by verifying (510, 512) the resource identifier. The data in the storage request is stored at the storage node if the resource identifier is successfully verified.

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： Multiple protocol tunnels (e.g., IPsec tunnels) are deployed to enable an access terminal that is connected to a network to access a local network associated with a femto access point. A first protocol tunnel is established between a security gateway and the femto access point. A second protocol tunnel is then established in either of two ways. In some implementations the second protocol tunnel is established between the access terminal and the security gateway. In other implementations the second protocol tunnel is established between the access terminal and the femto access point, whereby a portion of the tunnel is routed through the first tunnel.

摘要： Methods and apparatus for enhanced overlay state maintenance in a peer-to- peer overlay network. A first method includes inferring that a first node is leaving the overlay network, and transmitting a decrement message to decrement a size counter value. A second method includes identifying a set of nodes associated with a first node of an overlay network, obtaining a segment length associated with each node of the set of nodes, and determining a size of the overlay network by dividing the total number of nodes in the set of nodes by the sum of the segment lengths. A third method includes identifying a set of nodes associated with a first node of an overlay network, obtaining a size estimate associated with the first node and with each node of the set of nodes, and determining a size of the overlay network by averaging the size estimates.

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： 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 multi-party commitment method is provided whereby a joining node uses contributions provided by contributor nodes in a peer-to-peer overlay network to generate a node identifier. The joining node generates a first contribution and sends a join request to an introducer node (or a plurality of contributor nodes), where the join request seeks to obtain one or more contributions for generating the node identifier within an identifier space of the overlay network. A hash of the first contribution may be included as part of the join request. In response, the joining node may receive a plurality of contributions, wherein the contributions are bound to each other and the first contribution by a prior external multi-node commitment operation. The joining node can then generate its node identifier as a function of the first contribution and the received contributions. Consequently, collusion between nodes and malicious manipulation during ID generation can be frustrated.
摘要翻译：提供多方承诺方法，由此加入节点使用由对等覆盖网络中的贡献者节点提供的贡献来生成节点标识符。加入节点生成第一贡献并向引导者节点（或多个贡献者节点）发送加入请求，其中加入请求试图获得用于在覆盖网络的标识符空间内生成节点标识符的一个或多个贡献。第一个贡献的散列可以作为加入请求的一部分包含在内。作为响应，加入节点可以接收多个贡献，其中贡献彼此相关并且第一贡献通过先前的外部多节点承诺操作。随后加入节点可以根据第一贡献和接收到的贡献生成其节点标识符。因此，ID生成期间节点之间的串通和恶意操作可能会受挫。
