KNX Secure Header

Welcome to KNX Secure!

This page offers you all information and material about security measurements, which are implemented in the KNX Standard. KNX Secure guarantees you the highest security, which is available in the market for home and building control.

It contains all necessary information for you to either develop KNX devices according to the highest security standards, or make your own installation safer. Check out the various tabs and also the download section for more information.

Why is security in home and building important?

They exist – the hackers – who intrude in building technology. Jesters switch on the lights at the neighbour’s and boast of it. However, criminal energy and related knowhow can cause immense damage. Therefore, KNX Security is a red-hot subject. Already up to now KNX complies with the security requirements, as long as installers of Home and Building Control take care of the recommended protective measures against manipulations. Yet, new media like LAN and WLAN with internet access, wireless operation concepts and applications in sensible areas increase the risk of damage by unwanted intruders.

What is KNX Secure?

The safety requirements of KNX installations are growing. Critical and confidential information is increasingly transmitted due to extended application areas. These are for instance:

  • information on consumption data that should not be seen by third parties,
  • signals of locking systems (e.g. door contacts) which have to be protected against manipulation,
  • KNX devices for critical functions, which only shall communicate with authenticated participants,
  • data protection in security applications; here the code for the access system or even for setting/unsetting an alarm system may only be sent in encrypted and not in clear form.

How to protect in future even better media and devices of KNX installations will be an increasing challenge for planners, installers and manufacturers.

According to these but also to other requirements KNX has developed new security concepts: KNX Data Secure and KNX IP Secure. Both of them are based on worldwide established security protocols and can be integrated seamlessly into existing KNX systems.
