Abstract: Extensive research has been performed in recent years for the identification of wireless devices from their radio frequency (RF) emissions. The main idea of identifying a wireless device through its RF emissions is that the electronic circuits and the RF components have specific characteristics determined by the production and manufacturing processes. These characteristics, which result in unique differences, can be used to distinguish a wireless device from another. The RF components can include filters, amplifiers, oscillators and other electronics, which are used to compose and transmit the RF signal. The differences on the electronic components are randomly generated, and are mainly due to imperfections in the material or the component itself The possibility of identifying wireless devices from their RF fingerprints can be used for multi-factor authentication, where a wireless device can be authenticated not only on the basis of conventional cryptographic methods but also by processing the RF fingerprints. Another potential application is to fight against the distribution of counterfeit products.
