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.

The system comprises a plurality of execution nodes each configured to execute a network function by registering; and a manager node for registering each of the plurality of execution nodes, assigning a node identifier (Node ID) to each of the plurality of execution nodes, periodically polling each of the plurality of execution nodes for a status, and issuing control instructions to each of the plurality of execution nodes based upon the status of a respective execution node. Each of the plurality of execution node responds to the polling by transmitting its status to the manager node. The status includes runtime information and pre-configuration information.

摘要： A mechanism by which handoff delay can be minimized while not compromising the IMS/MMD security and also protecting the media if required by certain applications is presented. Methods for mitigating delay during SA re-association and mitigating the IPSec tunnel overhead for signaling and media at the Mobile Node are given. In one embodiment, SA keys can be transferred from the old P-CSCF to new P-CSCF, enabling the establishment of SAs before Mobile Node physically moves to the new subnet in a network. Proactive handover is used. In another embodiment, SA keys are transferred from S-CSCF to new P-CSCF. In this case, the SA keys are transferred to the new P-CSCF by S-CSCF through a context transfer mechanism well in advance so that SAs may be established before Mobile Node physically moves to new subnet. In another embodiment, methods for mitigating IPSec tunnel overhead are presented.

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.
摘要翻译：提供方法和系统以促进域内迁移。第一网络或域包括移动节点的归属代理或SIP代理。第二网络包括两个或多个子网络和至少一个移动性代理（MA）。每个子网包括相关联的子网代理。为了通信，移动节点首先向子网代理注册，接收地址转交地址和全局转交地址，然后向MA注册。然后，移动节点可以向归属代理提供全局转交地址。本地转交地址可以实现与移动节点的通信，而无需确定到移动节点的特定路由。从子网代理接收到的全局转交地址可能包括MA的地址。因此，移动节点可以从任何子网转换到另一个子网，而不需要与归属代理相关的关于转换的信息进行通信，并且不与移动节点和归属代理之间的安全关联的MA信息通信。

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.
