Prevent reinstallation of an already in-use group key Track the current GTK and IGTK that is in use and when receiving a (possibly retransmitted) Group Message 1 or WNM-Sleep Mode Response, do not install the given key if it is already in use. This prevents an attacker from trying to trick the client into resetting or lowering the sequence counter associated to the group key.
