Kavitha Kamarthy has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: In one embodiment, a Home Agent receives a Mobile IP registration request from a group member, where the group member is a Mobile Node. The Home Agent generates a mobility binding for the group member that associates the group member with a care-of address, wherein the group member is a member of one or more groups. The Home Agent generates a Mobile IP registration reply, where the Mobile IP registration reply identifies one or more key servers. Each of the one or more key servers serves at least one of the one or more groups and is adapted for distributing group cryptography material to members of each group that is served by the corresponding key server. The Home Agent sends the Mobile IP registration reply to the group member, thereby enabling the group member to obtain cryptography material for at least one of the one or more groups from at least one of the one or more key servers to enable the group member to use the cryptography group material to securely communicate with other group members.
Abstract: In one embodiment, group member devices may be divided into at least one cluster, wherein each cluster includes a primary key server designated to synchronize with a master key server. Each cluster further includes at least one registration server configured to communicate with member devices in the group within the cluster and to synchronize with the primary key server.

Abstract: A system and method directed to carrying out dynamic secured group communication is provided. The method includes obtaining a first packet that includes a first header. The first header includes a first source address of a first source node of a first network, and a first destination address of a first destination node of the first network. The method also includes forming a frame that includes the first header in encrypted form, combining the first header and the frame to form a second packet, and forming a second header. This second header includes a second source address of a second source node of a second network, and a second destination address of a second destination node of the second network. The method further includes encapsulating the second packet with the second header to form a third packet, and communicating the third packet into the second network from the second source node for termination to the second-destination node.

Abstract: Various systems and method are disclosed for automatically disseminating key server contact information in a network. For example, one method (e.g., performed by a discovery server) involves generating a discovery message that includes at least one list of one or more key servers and then sending that discovery message to one or more members of a key management protocol group. Each list of key servers can include contact information for one or more key servers and indicate the priority of each key server relative to other key servers within the list.
