20100290625	Secure group communications - A device for use in a system with multiple receiving units, and multiple intermediate units each configured to communicate with the device and at least some of the multiple receiving units, includes a communication module configured to send information toward and receive information from the receiving units and the intermediate units, a memory, and a processor coupled to the memory and the communication module. The processor is configured to: cause the communication module to send information toward each of the receiving units sufficient for the receiving units to obtain a key chain corresponding to that receiving unit, each key chain containing a plurality of keys, each key in each key chain being related to other keys in the respective key chains by at least one inverse of a one-way function; select a key from a key chain associated with a particular receiving unit and stored in the memory; and cause the communication module to send the selected key, and an indication of which receiving unit the selected key is associated with, toward the intermediate unit associated with the particular receiving unit.	11-18-2010

20100125899	REMOTE ACCESS TO LOCAL NETWORK VIA SECURITY GATEWAY - 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.	05-20-2010

20100049869	Methods and Apparatus for Event Distribution and Routing in Peer-to-Peer Overlay Networks - Methods and apparatus for event distribution and routing in peer-to-peer overlay networks. A method is provided for event distribution and routing in a peer-to-peer overlay network that comprises a plurality of nodes. The method includes identifying a plurality of buckets on the overlay network, wherein each bucket includes one or more nodes, respectively, identifying bucket groups, wherein each bucket group includes a selected number of buckets, respectively, distributing events based on the bucket groups, and updating a routing table based on the events. A node includes a transceiver and a processor coupled to the transceiver and configured to identify a plurality of buckets on the overlay network, wherein each bucket includes one or more nodes, respectively, identify bucket groups, wherein each bucket group includes a selected number of buckets, respectively, distribute events based on the bucket groups, and update a routing table based on the events.	02-25-2010
