摘要： A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.
摘要翻译：提供了一种用于广播消息安全性的新颖的组密钥分配和管理方案，其允许接入终端发送用组密钥加密的广播消息的单个副本。作为接入终端的有效的接入节点组的成员的接入节点可以解密和理解消息。组密钥由接入终端使用临时单播密钥生成并分发给其活动集中的接入节点，以在分发期间保护组密钥。每次从接入终端的活动接入节点集中移除接入节点时，都会提供一个新的组密钥。

摘要： A method is provided for securing a PMIP tunnel between a serving gateway and a new access node through which an access terminal communicates. A PMIP key hierarchy unique to each access terminal is maintained by the gateway. The gateway uses a first node key to secure PMIP tunnels when authentication of the access terminal has been performed. A PMIP key is generated based on the first node key and the PMIP key is sent to the new access node to assist in establishing and securing a PMIP tunnel between the gateway and the new access node. Otherwise, when authentication of the access terminal has not been performed, the gateway generates a second node key and sends it to an intermediary network node which then generates and sends a PMIP key to the new access node. This second key is then used to secure the PMIP tunnel.
摘要翻译：提供了一种用于保护服务网关和接入终端通过的新接入节点之间的PMIP隧道的方法。每个接入终端唯一的PMIP密钥层级由网关维护。当已经执行接入终端的认证时，网关使用第一节点密钥来保护PMIP隧道。基于第一节点密钥生成PMIP密钥，并将PMIP密钥发送到新的接入节点，以协助建立和保护网关与新接入节点之间的PMIP隧道。否则，当接入终端的认证尚未被执行时，网关生成第二节点密钥并将其发送到中间网络节点，然后生成PMIP密钥并将其发送到新的接入节点。然后第二个密钥用于保护PMIP隧道。

摘要： A novel key management approach is provided for securing communication handoffs between and access terminal and two access points. This approach provides for securely handing off communications between an access terminal and access point without risking exposure a master key for the access terminal. Temporary master keys are derived for low latency handoffs and secure authentication between a new access point and the access terminal. In one aspect, a distributive key management scheme is provided in which a current access point generates a new security key (based on its own security key) that is used by the next access point with which an access terminal communicates. In another aspect, a centralized key management scheme is provided in which a central authenticator maintains, generates, and distributes new security keys (based on a master security key associated with the access terminal) to access points.

摘要： An inbound message is received over a scalable adaptive modulation ("SAM") interface (104). The inbound message comprises a SAM layer 2 ("L2") header and data in which the SAM L2 header encapsulates. A hardware L2 address is identified for the first device from the encapsulated data and a SAM L2 address is identified for the second device from the SAM L2 header. Once both addresses are identified, an association between the hardware L2 address of the first device and the SAM L2 address of the second device is stored. Similarly, the association may be made between the hardware L2 address of the first device and the SAM L2 address of the first device, or between an Internet protocol ("IP") address of the first device and a SAM L2 address of a second device or the first device.

摘要： Router elements R1, R2 of a packet network 100 using a sparse mode multicast protocol are configured as candidate rendezvous points (RPs). The candidate RPs use a virtual IP address. In each shared subnet, there is selected from among the candidate RPs a single designated candidate rendezvous point (DCRP) and zero or more virtual candidate rendezvous points (VCRPs). The DCRP serves as an active candidate RP (and when elected, performs RP functions); and the VCRP(s) serve as backup to the DCRP. The VCRP(s) maintain state information to facilitate rapid takeover of DCRP functionality upon failure of the DCRP. In one embodiment, geographically separate domains 1006, 1008 are each implemented with separate active DCRPs, defining multiple, simultaneously active anycast RPs (DCRP1, DCRP2) with MSDP peering between the DCRPs. The DCRP(s) may include backup VCRP(s) for redundancy.
