KNX: maximum data protection for smart buildings

Officially recognised by international standardisation bodies as meeting the highest security requirements in cyber security worldwide, KNX Secure is being showcased at ISE. KNX Secure meets standard EN 50090-4-3 and, internationally, relies on security algorithms standardised according to ISO 18033-3, such as AES 128 CCM encryption, in order to effectively prevent attacks on the digital infrastructure of buildings and to achieve the highest level of data protection

Franz Kammerl, president of the KNX Association, commented: “In the past, burglars would enter buildings through doors or windows. Nowadays they enter through radio and communications networks. As buildings have become increasingly digitally networked, the nature of potential dangers has also changed. Only KNX has been delivering the most appropriate responses to these.”

KNX Secure essentially consists of two mechanisms. KNX IP Secure protects the IP communication between the KNX installations. For this purpose, KNX IP Secure extends the IP protocol in such a way that all transferred telegrams and data are completely encrypted. At the same time, KNX Data Secure effectively protects user data, including data exchanged with the various terminals, against unauthorised access and manipulation by means of encryption and authentication. Both mechanisms can be combined and used in parallel to achieve maximum safety.
