Abstract(in Japanese) (See Japanese page)
Abstract(in English) It is well known that there is the Shannon limit for information theoretic security of the conventional symmetric key cipher. However, it is pointed out that the Shannon limit is not an absolute limitation. Hence it should be denoted that the conventional ciphers belong to the Shannon theoretical frame. If one can show a counter example, one may say that it is outside of the Shannon frame. Yuen protocol so called Y-00 is an example of the ciphers which get out of the Shannon frame. Y-00 consists of Gauss private randomization and quantum measurement theory. There are still negative campaign against Y-00 based on the irrelevant paper. This paper proves that Y-00 cannot be described by Shannon theory, showing an explicit example.
