Abstract (in Japanese) (See Japanese page) 
(in English) In designing symmetric key cryptography, it is essential to be sufficiently resistant to differential attacks. Differential attack is a decryption method that estimates the key based on the correlation that exists between the input difference and the output difference. In order to perform a difference attack, it is necessary to find the maximum difference characteristic probability. In addition, from the nature of the difference, it can be seen that there is a multipath in which the difference attack is effective for arbitrary input differences.Taking advantage of this, we discovered a multipath in which a full-round differential attack is effective against the block cipher DoT.
