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

摘要： Disclosed is a method for user identity authentication for a peer device joining a peer-to-peer overlay network. In the method, a credential server of the overlay network receives a registered user identity from a joining peer device. The credential server verifies the registered user identity with an identity provider. Upon receiving, at the credential server, successful verification of the registered user identity from the identity provider, the credential server issues to the joining peer device a signed certificate for use by an authenticated peer device in the overlay network to authenticate the registered user identity of the joining peer device, wherein the signed certificate is signed by a private key of the credential server.
