Downloadable Program can Decrypt Z-Wave Encryption
« on: December 31, 2013, 10:18:30 pm »
I wanted to get opinions on this video. It shows a group making a program to decrypt the AES encryption of the Zwave doorlocks on the fly.

Any opinions?
Should we bother with security in our Zwave installations?

I don't believe it actually decrypts the packets on the fly.. But it is able to reset the encryption key to their choosing so essentially they take over the lock.

It appeared to exploit a bug in one vendor's lock.

Have a read of the master topic.
Dezwaved at the moment...
