Title: Key management protocol
Inventor: SOPPERA ANDREA
IPC: H04L29/06
Filed: 2003-03-14
Abstract: A key distribution server maintains a tree of nodes. Members of a group who are allowed access to information are associated with respective leaf nodes of the tree. The information is encrypted with a key comprising a join key fiel d and a leave field, and these are associated with the root node of the tree. The join key is updated each time a member joins the group and the leave fie ld is updated each time a member leaves. Further respective leave keys are associated with the other nodes of the tree. The leave keys of the tree are related so that a member knowing the leave key of its node can work out the leave key of the root node and hence decrypt the information. The key distribution server transmits offset messages to the members to allow them s o to calculate the root node leave key. The system of offset messages reduces the amount of communication required between the key distribution server and the group members.

Title: Adaptive feedback technique implemented in mobile ip networks
Inventor: LEUNG KENT K
IPC: H04L12/56
Filed: 2003-06-23
Abstract: An adaptive feedback technique is described for a Mobile IP environment in which Mobile IP mechanisms provide early feedback to mechanisms in the transport layer and/or application layer of a mobile node in response to detection of changes in link characteristics of the communication used by the mobile node to communicate with a data network. Using the early feedback information, appropriate measures may then be taken in order to accommodate the changes in link characteristics. Such appropriate measures may include, for example, providing feedback to media aware applications in order to allow such applications to dynamically adjust their bandwidth requirements to accommodate the new link characteristics, modifying timeout parameters, modifying an encoding formats to accommodate the new link characteristics, notifying participants in a real-time application session of the detected changes in the link characteristics, etc.
