| Abstract(in English) | As an information-theoretically secure key distribution system for wireless communication, a secret key agreement system exploiting ESPAR antenna was proposed. In this paper, we propose directivity set preparation method, and adaptive directivity set selection method according to noise environment. This two method aim to improve Imac (information mutual anti-tapping condition). As a 16bit-key simulation result, the directivity set preparation method saves transmitted power by 5.7dB compared with the mean of random selection. And the adaptive directivity set selection method saves 7.1dB. |
