The main goal of this work is to incorporate security in an existing Ultra Wide Band (UWB) network. The authors present an embedding method where a tag is added at the physical layer and superimposed to the UWB-impulse radio signal. The tag should be added in a transparent way so that guaranteeing compatibility with existing receivers ignoring the presence of the tag. They discuss technical details of the new embedding method. In addition, they discuss embedding strength and they analyze robustness performance. They demonstrate that the proposed embedding technique meets all the system design constraints.
