摘要： A spatio-temporal random voting scheme is provided that incorporates location distribution, spatial randomness, and temporal randomness in the collection of information from a plurality of sensing devices within the cognitive network. The region is divided into a plurality of sectors, where each sector is a portion of the region. A subset of sectors is selected from the plurality of sectors in the region to provide spatial randomness. A device is randomly selected from each sector in the subset of sectors to provide additional spatial randomness to the information collection process. Temporal randomness may be introduced by randomly selecting a timeslot within a sensing window period in which devices are to scan a frequency spectrum band to determine if a signal energy above a threshold is detected. Sensing reports are then collected from the selected sensing devices and used to determine whether the frequency spectrum band is available or in use.

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： 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： A logical tree structure and method for managing membership in a multicast group provides scalability and security from internal attacks. The structure defines key groups and subgroups, with each subgroup having a subgroup manager. Dual encryption allows the sender of the multicast data to manage distribution of a first set of encryption keys whereas the individual subgroup managers manage the distribution of a second set of encryption keys. The two key sets allow the sender to delegate much of the group management responsibilities without compromising security because a key from each set is required to access the multicast data. Security is further maintained via a method in which subgroup managers can be either member subgroup managers or participant subgroup managers. Access to both keys is provided to member subgroup managers whereas access to only one key is provided to participant subgroup managers. Nodes can be added without the need to generate a new encryption key at the top level which provides improved scalability.

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, apparatus, and systems to perform secure registration of a femto access point for trusted access to an operator-controlled network element. Method steps include establishing a security association for at least one said femto access point, making a request using the security association to an operator-controlled network element, which requests a secure registration credential from an authorizing component. The operator-controlled network element constructs a secure registration credential and sends the secure registration credential to the requesting femto access point, thus authorizing trusted access by the requesting femto access point to access operator-controlled network elements. Embodiments include establishing a security association via an IPsec security association received from a security gateway which is within an operator-controlled domain and using an operator-controlled database of IPsec inner addresses. In some embodiments the femto access point conducts message exchanges using one or more IMS protocols and components, including call session control function elements, which elements in turn may authorize a femto access point within the IMS domain, may or access non-IMS network elements for authorization.
