Abstract(in English)	Recently cryptanalysis for the block ciphers , particularly linear and differential cryptanalysis are improved. As a countermeasure for them, new methodology, for constructing block ciphers with security against differential and linear cryptanalysis are constructed, some of them are constructed by highly nonlinear functions and are called as "provably secure", but there is some doubt. In this paper, the fact is showed by the example, that by extending linear cryptanalysis perfect nonlinear functions can be attacked.
