| Abstract(in English) | The schemes of secret key agreement based on channel characteristics have been proposed for countermeasure against eavesdropper in radio communication systems using carrier modulation. This paper proposes the new scheme of secret key agreement for UWB system using impulse waves, because it is difficult to apply the conventional scheme to UWB system. The proposes scheme employs the differences of arrival time among direct wave and delay waves, which are measured at both authorized radio station changing the transmitter and receiver side. The proposed scheme also employs the countermeasure for the detection error of delay waves which differ the arrival times at both radio stations. The computer simulation is carried out to evaluate the performance of the proposed scheme in the wireless PAN environment. The computer simulation shows that the proposed scheme can achieve the key agreement without errors at signal-to-noise ratio of 25dB. |
