International. KNX, an international technical standard in the smart housing and building sector, has reached a new milestone in its development. KNX IP Secure has been recognized as an international security standard, with EN ISO 22510.
The new ISO standard was published at the end of November 2019 and was created specifically to cover open data communication for building automation and building management via KNXnet/IP.
"With continued progress in building and infrastructure smart grids, including trending topics such as sector coupling, smart grids, etc., there are an increasing number of data-driven use cases in KNX projects that rely on highly sensitive data and require particularly high levels of security. This is exactly where we started with KNX Secure, in which we expanded our already very secure standard with additional security mechanisms to meet the highest IT security demands," says Franz Kammerl, President of the KNX Association.
KNX Secure, which was already created in 2015, is based on international security algorithms standardized according to ISO 18033-3 and uses recognized encryption according to AES 128 CCM. KNX Secure essentially consists of two mechanisms: KNX IP Secure protects IP communication between KNX installations. For this purpose, KNX IP Secure extends the IP protocol in such a way that all telegrams and data transferred are fully encrypted. At the same time, KNX Data Secure effectively protects user data, including data exchanged with individual terminals, against unauthorized access and manipulation through encryption and authentication. Both mechanisms can be combined and used in parallel to achieve maximum safety in smart buildings.
