Improved Higher-Order Differential Attacks on MISTY1
Achiya Bar-On
Abstract
MISTY1 is a block cipher designed by Matsui in 1997. It is widely
deployed in Japan, and is recognized internationally as an European
NESSIE-recommended cipher and an ISO standard. Since its introduction,
MISTY1 was subjected to extensive cryptanalytic
efforts, yet no attack significantly faster than exhaustive key search is
known on its full version. The best currently
known attack is a higher-order differential attack presented by Tsunoo
et al. in 2012 which breaks a reduced variant of MISTY1 that contains
7 of the 8 rounds and 4 of the 5
