摘要： The present invention provides location privacy against third parties while allowing route-optimized communication between the correspondent node and the mobile node. The mobile node's home address is hidden from an external observer thereby thwarting traffic analysis based attacks where a Home Address is correlated with a Care of Address of a mobile node (MN). A “privacy label” is used in place of a home address associated with the mobile node. The privacy label is supplied by the mobile node to the correspondent node in a way that that allows the privacy label to be bound to the home address, but does not allow the home address to be visible during the exchange. The privacy label may be also used to help prevent against replay attacks.
摘要翻译：本发明提供了针对第三方的位置隐私，同时允许通信节点和移动节点之间的路由优化通信。移动节点的归属地址被外部观察者隐藏，从而阻止基于业务分析的攻击，其中归属地址与移动节点（MN）的地址关联相关联。使用“隐私标签”代替与移动节点相关联的归属地址。隐私标签由移动节点以允许隐私标签绑定到家庭地址的方式提供给通信节点，但是不允许家庭地址在交换期间可见。隐私标签也可用于帮助防止重放攻击。

摘要： An apparatus, system, and method are directed to managing connectivity in a network by expediting the ability of a mobile node to send Internet Protocol (IP) packets subsequent to a handover. The mobile node is configured to determine an unconfirmed address for use on an access router. Upon establishing a link-layer connection, and before establishing a network-layer connection with the access router, the mobile node employs the unconfirmed address to send an IP packet to the access router. Employing the unconfirmed address prior to network-layer connectivity enables the reduction of handover latencies. If the access router determines that the unconfirmed address conflicts with an existing address, the access router provides a message to the mobile node indicating the conflict in addresses. In response to the message, the mobile node performs actions to resolve the address conflict.
摘要翻译：设备，系统和方法旨在通过加速移动节点在切换之后发送因特网协议（IP）分组的能力来管理网络中的连接性。移动节点被配置为确定在接入路由器上使用的未确认地址。在建立链路层连接之后，在与接入路由器建立网络层连接之前，移动节点采用未确认地址向接入路由器发送IP分组。在网络层连接之前采用未确认的地址，可以减少切换延迟。如果接入路由器确定未确认地址与现有地址冲突，则接入路由器向移动节点提供指示地址冲突的消息。响应该消息，移动节点执行解决地址冲突的动作。

摘要： A system and method is provided that enables the transfer of policy resource tokens (PRT) in the process of a handover of a mobile node in a wireless network. The system includes a granting agent that grants the PRT to a first access router to enable the mobile node to access network resources. In one embodiment, in the process of handing over the mobile node, the first access router provides the PRT to the second access router, thereby reducing data latency, and a disruption for an application executing on the mobile node. In another embodiment, the mobile node provides the PRT to the second access router after connectivity is established. A PRT data structure also is provided that includes a data field of profile types. A profile type describes context authorization information for granting access to a network resource.

摘要： An embodiment of the invention is a method and corresponding system for improved network address translation (NAT) operation, to enable efficient translation for packets destined for communication systems within a domain utilizing network addresses that are incompatible with source and destination addresses indicated in packets delivered from the global Internet. Since the addresses are not compatible with global Internet addresses, delivery cannot be accomplished except by some method of address translation. Traditional systems have not been constructed to enable such inbound translations, providing, instead, only communication outbound from the incompatibly addressed domain towards the global Internet. The example embodiment employs history and pattern matching between observable characteristics of the inbound payload, associated over time with specific destinations. The example embodiment may also employ DPI search techniques known from widely deployed systems in use today, to identify a field on which the pattern matching may operate.

摘要： A method of structuring vectorized data obtained by scanning a drawing or other document comprising the steps of displaying on a computer controlled display screen a template image comprising template lines and nodes corresponding to the acquired image data and selecting portions of the acquired image data to be designated for inclusion in a restructured image data set by using a screen cursor to select the corresponding template lines displayed on the screen. Inclusion designations are subsequently and selectively removed as desired from portions of the acquired image data from the structured data set by using the cursor to select the corresponding lines and nodes on the screen. When the desired portions of the acquired data set are selectively designated for inclusion in the restructured data set, all remaining designated data is copied into the restructured image data.
