Abstract (in Japanese) (See Japanese page) 
(in English) In Wyner's wiretap channel, information leakage is defined as mutual information between transmitter's messages and eavesdropper's received symbols.
However, calculating the mutual information as defined requires exponential time,
which makes it hard to know the amount of information leakage when the way of encoding is given.
For this problem, we introduced a new criterion named the information leakage given wiretapper's received symbols (conditional information leakage).
We discussed the security in binary symmetric channel (BSC) and binary erasure channel (BEC) using this criterion in the previous research.
In this paper, we study the security in binary symmetric erasure channel (BSEC).
