Abstract (in Japanese) (See Japanese page) 
(in English) With the spread of the wireless communications, secret key agreement schemes on physical layer attracts attentions for protecting communications from eavesdropping. As an example, there is a scheme quantizing time-varying received signal strength or channel coefficient to generate keys. Another is a scheme using multi-antenna at an authorized station in the case of the static channel. This scheme updates channel coefficients of equivalent channel between single antennas every discrete sample with weights of antennas to generate artificially fading. These have problems that noises change keys near threshold when received signal strength is quantized. This paper focuses the secret key agreement scheme using multiple-antenna and shows performance of noise reduction and impact on eavesdropping resistance with averaging operation.
