  Mitsuru Matsui - Encyclopedia, History, Geography and Biography
Mitsuru Matsui is a Japanese cryptographer and senior researcher for Mitsubishi Electric Company.
While researching error-correcting codes in 1990, Matsui was inspired by Biham and Shamir's differential cryptanalysis, and discovered the technique of linear cryptanalysis, published in 1993.
The following year, Matsui was the first to publicly report an experimental cryptanalysis of DES, using the computing power of twelve workstations over a period of fifty days.

 Crypt::Misty1 - Crypt::CBC-compliant block cipher
Designed by Mitsuru Matsui, the inventor of linear cryptanalysis, Misty1 is the first cipher that is provably secure against linear and differential cryptanalysis.
It was developed by Mitsuru Matsui, and is described in the paper New Block Encryption Algorithm MISTY and in RFC2994.
In January of 2000, the 3GPP consortium selected a variant of Misty1, dubbed as KASUMI (the Japanese word for ``misty''), as the mandatory cipher in W-CDMA.

 Introduction to Cryptography - principles and systems
The differential cryptanalysis introduced by Eli Biham and Adi Shamir in late 1980's was the first attack that fully utilized this idea against block ciphers (especially against DES).
Later Mitsuru Matsui came up with linear cryptanalysis which was even more effective against DES.
There can be found Mitsuru Matsui's discussion of linear cryptanalysis of DES, and the ideas of truncated differentials by Lars Knudsen (for example, IDEA cryptanalysis).

 MISTY
The block cipher MISTY, developed by Mitsuru Matsui for the Mitsubishi Corporation, was the first cipher to demonstrate a novel method of obtaining a level of provable security against both differential and linear cryptanalysis.
A paper explaining these basic principles in the context of the closely related block cipher KASUMI is available on the web.
Note that keys consisting of eight identical 16-bit subblocks may be considered weak; but, of course, any keys belonging to a known small family would be weak against a brute-force search in any case.

It's based around a single PC that sits at a secure center, said Mitsuru Matsui, a senior manager with Mitsubishi Electric's information security technology department, at a Tokyo news conference.
A single key is issued by the PC to each box, both of which are connected via a fiber optic link to companion boxes at distant locations.
Current systems are limited to a distance of about 100 kilometers but with the center sitting between two networks the communications distance is effectively doubled.

In cryptography, MISTY1 (or MISTY-1) is a block cipher designed in 1995 by Mitsuru Matsui and others for Mitsubishi Electric.
MISTY1 is one of the selected algorithms in the European NESSIE project, and has been recommended for Japanese government use by the CRYPTREC project.
"MISTY" can stand for "Mitsubishi Improved Security Technology", it is also the initials of the researchers involved in its development: Matsui Mitsuru, Ichikawa Tetsuya, Sorimachi Toru, Tokita Toshio, and Yamagishi Atsuhiro [1].
