Abstract (in Japanese) (See Japanese page) 
(in English) The privacy amplification is a technique to distill
a secret key from a random variable by a function
so that the distilled key and an eavesdropper's
random variable is statistically independent.
There are two kinds of security criteria for the
key distilled by the privacy amplification:
the weak security criterion and the
strong security criterion. As a technique to distill
a secret key, it is known that the encoder of a
Slepian-Wolf (the source coding with
full side-information at the decoder)
code can be used as a function
for the privacy amplification if we employ the weak
security criterion. In this paper, we show that
the encoder of a Slepian-Wolf
code cannot be used
as a function for the privacy amplification
if we employ the strong security criterion.
