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.
