This European Standard defines security for HBES communication.It is based on ISO/IEC 24767-2, Home network security / Secure Communication Protocol Middleware (SCPM).Having a secure HBES solution has several advantages.-It makes the HBES RF Communication Medium more secure:HBES RF Radio Frames in plain communication can easily be traced (by sniffer for example).-It allows for secure applications.Secure communication is interesting in shutter - and door control and anti-intrusion security, in order to prevent intrusive commands (burglars...).It is also interesting in metering to protect for example electrical consumption data.This document does not define any type of application.
