DNAX-BCU: An Un-clonable Cost-conscious SoPC Implementation for Bus Coupling Units of the European Installation Bus

In this article a Bus Coupling Unit KNX/EIB standard for Building Automation Systems is presented. The proposed architecture exploits the flexility and computation power of the reconfigurable devices to overcome the limitations of the embedded platform proposed in the standard. Furthermore, the approach takes advantage from the facilities that the new in-system Flash FPGAs provide: a unique code for each device (DNA) and internal One-Time-Programmable registers.The proposed architecture is presented and an implementation of this system on a Spartan3-AN FPGA is reported and discussed.
