Abstract (in Japanese) (See Japanese page) 
(in English) There is increasing interesting about Secret key Agreement Scheme based on radio wave propagation characteristics as physical layer security. In the secret key generation based on the sampling time series of the fading fluctuation, the decision of the sampling interval is important from the viewpoint of the independence of the time series and the efficiency of key generation, but the appropriate sampling interval is not sufficiently studied. This paper investigates the upper limit of the sampling interval which does not occur in the loss of information, and investigates the lower limit of the sampling interval where the independence of the time series is maintained. This paper also investigates the secret key capacity of the key generated form multilevel quantization. The simulation results show that 1/2 and 1/4 of the maximum Doppler frequency are appropriate sampling intervals in quadrature detection and envelope detection, respectively. The simulation results also show that sufficient secret key capacity can be obtained by multilevel quantization.
