Realising secured data transmission in KNX salvatore cavalieri

The paper deals with the problem of making secure data transmission inside home and building automation environment; as known, here data exchanged may be critical, as they may regard commands to actuators and/or private and secret information. The need to protect critical data has led to introduce secure transmissions inside communication systems used for home/building automation applications. The paper deals with this problem taking into account the KNX communication system, which, at this moment, doesn´t foresee any security and authentication mechanisms. A security and authentication solution will be presented and assessed comparing it with the current state of the art.
