Abstract: We present an efficient identity-based key management scheme for group communications (ID-GC). ID-GC out-performs all existing group key management schemes in terms of reducing the communication overhead for group management, e.g., adding or deleting group members. In average cases, ID-GC requires O(log N) messages for removing multiple members and 1 message for adding a new group member, where N is the group size. ID-GC scheme provides group forward/backward secrecy, and it is resilience to colluding attackers.
