| Abstract(in English) | MISTY is a block cipher recently proposed by M.Matsui. But for it, K.Sakurai and Y.Zheng showed that 3 iterations of basic transformations of MISTY does not yield a pseudorandom permutation of Luby-Rackoff. In this reports, we show that 4 iterations of basic transformations of MISTY yields a pseudorandom permutation of Luby-Rackoff, and the Non-Pseudorandomness of 3L-round MISTY is due to its parallel computability, and by slightly changing the structure of MISTY so that it has no parallel computability, 3 iterations yield a pseudorandom permutation of Luby-Rackoff. |
