I think that this is not the Secure Z-Wave Binding.
This seems to me that this is the latest “regular” snapshot binding (I will double check also)
Did you follow the installation instructions here: OH2 Z-Wave refactoring and testing... and SECURITY - #6 by chris
You need to copy the network key (use HABmin), delete your Z-Wave things (PaperUI), uninstall the Z-Wave binding (PaperUI) and then install the new *.jar file manually.
Let me know if you need help with any of the above
