Message integrity means that the receiver can be sure that the message received was sent by a secure node in the network and that this message has not been altered. Messages sent by radio transmitters outside the network will be recognized as fakes.
Confidentiality means that only secure nodes in the network can read the actual contents of the message. For all other radio receivers, the payload of encrypted messages sent appears as random data.
Data Freshness means that the message has been sent recently.
The Z-Wave security solution comprises of two parts:
Each part or combinations provides protection, detection or reaction against a number of security attacks.
Security is achieved by transforming outgoing messages using encryption and a message authentication code (MAC).
To maintain backward compatibility and interoperability, both the secured and non-secured Z-Wave devices can operate in the same Z-Wave network.
The Z-Wave security solution supports networks with mixed secure and non-secure communication in order to leverage on the existing non-secure products. Both secure and non-secure nodes can participate in the routing algorithm.
It is up to the implementation of each application to decide which commands should be supported using security encapsulation. For example, a device may choose to support all its command classes non-secure if it is being included to a non-secure network, but no command classes non-secure if it is included securely.
