| Abstract(in English) | As a countermeasure against eavesdropping in wireless communications the wireless steganography technique has been proposed and the fundamental performance of the technique was evaluated. In this paper, we proposed a new wireless steganography using nonlinear amplifier in OFDM system. By computer simulations we evaluate the performance of the proposed system such as the transmission characteristics of the cover signal and the embedded signal between authorized stations, and the anti-steganalysis performance against eavesdroppers. As result, the wireless steganography using nonlinear amplifier in OFDM system is superior to the conventional wireless steganography in terms of transmission characteristics between authorized stations and the tapping resistance to the steganalysis by eavesdroppers because of a use of nonlinear amplifier to hide the embedded signal. |
