8 KNX Security
The KNX standard was extended by KNX Security to protect KNX installations from unauthorized
access. KNX Security reliably prevents the monitoring of communication as well as the
manipulation of the system.
The specification for KNX Security distinguishes between KNX IP Security and KNX Data Security.
KNX IP Security protects the communication over IP while on KNX TP the communication remains
unencrypted. Thus, KNX IP Security can also be used in existing KNX systems and with non-
secure KNX TP devices.
KNX Data Security describes the encryption on telegram level. This means that the telegrams on
the twisted pair bus or via RF (radio frequency) are also encrypted.
Encrypted telegrams are longer than the previously used unencrypted ones. For secure
programming via the bus, it is therefore necessary that the interface used (e.g. USB)
and any intermediate line couplers support the so called KNX long frames.
