KNX Secure: security in the smart building

KNX Secure: security in the smart building
No manipulation and no recording of the data traffic: even in a smart building, data protection has the highest priority. For this reason, we use the world's first manufacturer and application-independent security standard for smart buildings. KNX Secure protects twice and secures all data with the AES128 algorithm.
1. Secured area
KNX Secure ensures high security with encryption and authentication in secured areas such as functional buildings or apartments and private utility rooms. Key management and isolation protect against unauthorised access.
2. Public area
Across public areas, the JUNG area and line coupler makes a secure KNX system possible. Despite physical accessibility, the data remain protected due to encryption, as the coupler separates the two KNX lines and secures them with KNX Secure.
Security due to intelligent JUNG topology

Doubly secure with KNX Secure

IP Secure
Independently of the medium, KNX IP Secure encrypts and authenticates all telegrams at the network level. The data transmitted are completely secure. Thus the communication between sensor and actuator in the IP network cannot be interpreted or manipulated. KNX IP Secure is the first manufacturer-independent security solution that is recognized as an international security standard in accordance with the EN ISO 22510 standard.
Data Secure
KNX Data Secure also encrypts the data on the bus line (twisted pair) or via wireless communication (RF). KNX secure prevents attack scenarios such as recording, replay attacks or man-in-the-middle attacks.
