RF identification and security technique for highly-secure UWB information systems

A simple and reliable technique for securing information systems is presented in this paper. This technique is based on extracting fingerprints from the measured transmission parameters of a microstructured multi-port device. A possible scenario for on-chip implementation of such approach is discussed as well. Similarity measures between all generated fingerprint-tuples are thoroughly studied and investigated. The generalized correlation matrix concept is also employed in order to have a complete insight of the uniqueness and similarity between the generated RFID functions. All measurements are performed in the UWB frequency range. The proposed technique can be a promising candidate for omnipresent physically secured embedded chip information applications.
