ABSTRACT:
In one embodiment, a method of forming a secure group from a plurality of nodes for communicating with a user A comprises performing a discover protocol, wherein after performing the discover protocol, all nodes belong to at most one small group and wherein all nodes in each small group share a common key. The method further comprises selecting a leader for each small group. The method further comprises, for each of the leaders, generating a respective common key for the user A and that respective leader. The method further comprises generating a key tree having a plurality of levels, wherein the keys for the lowest level of the key tree are the common keys generated for each leader and wherein the keys for each successive layer are generated by combining pairs of keys from lower levels of the key tree.
