as z-wave introduces the security model (AES ENCYPTION)but yet not implemented IT in the products, i think that it is quite vulnerable to
crack the z wave network.
for example, by launching the sniffer attack while the establishment of the network and distribution of the network key.
similarly one can tepmered the existing node and transfer the keys to some intruders (physical attack).
as zwave consist of alot of secure and unsecure nodes. the flooding techniques or replay of messages can also disturb the network.
at last the social attacks can effect the privacy of any zwave network. for example one can predict the owner activities by flow of trafic in between the sensor
nodes and then transform this information to some other situation. for example if you sniff your neighbour node activities then you may be able to predict when he is at home and when he goes to sleep and when he goes to wrk etc..
my question is that does any one ever suffered due to security limitation in z-wave or any one know how zwave thandels the above discribed situations ??
