Abstract (in Japanese) (See Japanese page) 
(in English) This paper deals with the secret key capacity of secret key agreement scheme using multiple antennas. It is assumed that one of two authorized stations has multiple antennas (array antenna), while the other and eavesdropper have single antenna. In multipath propagation environments, a series of received signals is obtained by changing antenna weight at random. Then, it is assumed that the distributions of received signals are Gaussian distribution. The formula of upper and lower bound of secret key capacity is derived based on the system model in the case of one and two eavesdroppers. This paper also examined the secret key capacity by computer simulation. As a result, it is shown that theoretical result agrees well with the simulated.
