    摘要: A media-independent handover key management architecture is disclosed that uses Kerberos for secure key distribution among a server, an authenticator, and a mobile node. In the preferred embodiments, signaling for key distribution is based on re-keying and is decoupled from re-authentication that requires EAP (Extensible Authentication Protocol) and AAA (Authentication, Authorization and Accounting) signaling similar to initial network access authentication. In this framework, the mobile node is able to obtain master session keys required for dynamically establishing the security associations with a set of authenticators without communicating with them before handover. By separating re-key operation from re-authentication, the proposed architecture is more optimized for a proactive mode of operation. It can also be optimized for reactive mode of operation by reversing the key distribution roles between the mobile node and the target access node.

    摘要: An inventive system and method for group communication among devices in M2M networks comprises associating one or more of the devices with a gateway having a unique identifier, initiating registration of the devices at an M2M network using the unique identifier of the gateway, providing from the network a temporary identifier to the gateway and associating, in the network, the temporary identifier with the gateway, attaching the devices to the network using the temporary identifier, and communicating information between the network and the device through the gateway. In one aspect, the devices can be classified into sub-groups and each sub-group has a sub-group head that can be attached to the gateway so that the devices can communicate with the network through the sub-group head instead of the gateway. Each sub-group can be associated with a unique temporary identifier, in addition to the temporary identifier associated with the gateway.

    摘要: The present invention, among other things, obviates the effects of an attack on a wireless network through appropriate isolation and recovery. An aspect of the present invention can include a system and method of isolating a victim of malicious behavior in a wireless access network, and in particular WLAN networks. By having software on the victim's device, the system provides the capability of recovering the victim from the effects of the intruder, and prevents the victim from being affected by subsequent attacks by the intruder. The preferred embodiments include two key components: a local monitor and a global monitor.

    摘要: Methods and systems are provided for facilitating intra-domain mobility. A first network or domain includes a home agent or SIP proxy of a mobile node. A second network includes two or more subnetworks and at least one mobility agent (MA). Each subnetwork includes an associated subnet agent. To communicate, the mobile node first registers with a subnet agent, receives a local care-of-address and a global care-of-address, and then registers with an MA. The mobile node may then provide the global care-of-address to the home agent. The local care-of-address may enable communication with the mobile node without determining a specific route to the mobile node. The global care-of-address received from the subnet agent may include the address of the MA. Accordingly, the mobile node may transition from any of the subnetworks to another subnetwork without communicating to the home agent information about the transition and without communicating to the MA information about a security association between the mobile node and the home agent.

    摘要: The Dynamic Registration and Configuration Protocol (DRCP) provides a framework for registering and passing configuration information to roaming mobile hosts. DRCP is compatible with DHCP can switch to using DHCP protocol if only DHCP servers are present in the network. Most importantly, DRCP allows rapid configuration by moving address consistency checking from the critical path. Other novel features of DRCP allow: a) clients to know when to get a new address independent of the layer-2 access technology, b) efficient use of scarce wireless bandwidth, c) clients to be routers, d) dynamic addition or deletion of address pools to any DRCP node, and e) message exchange without broadcast.
