Mitsubishi Electric has been strongly promoting
the information security business since 1996, the year MISTY1 was published.
In 2000, KASUMI, which is a variant of MISTY, was adopted as the mandatory
standard for the 3G mobile system W-CDMA. MISTY is now internationally
acknowledged as a strong and practical cipher. Also in 2000, Mitsubishi
Electric and NTT jointly designed the Camellia. Mitsubishi Electric is
currently offering these algorithms to various standardization bodies
such as the ISO, NESSIE and CRYPTREC for proposal. The Japan Ministry
of Public Management, Home Affairs, Posts and Telecommunications and the
Ministry of Economy, Trade and Industry have officially approved MISTY1
and Camellia for Japanese governmental use. It is most likely that the
NESSIE portfolio will be highly regarded as a vital component in the ISO
decision-making process while Mitsubishi Electric's encryption technology
becomes increasingly used on a worldwide scale.

MISTY
 MISTY was developed
by Mitsubishi Electric in 1995 and is a family name of two encryption algorithms
MISTY1 and MISTY2, which has the world's highest-level of security and practicability.
MISTY1 and MISTY2 are both a 64-bit block cipher with a 128-bit key, which
can be used for data communication and electronic commerce in open networks.
The MISTY specifications have been published in full.
Camellia
Camellia is a next-generation 128-bit block encryption
algorithm jointly developed by Mitsubishi Electric and NTT, and supports
three key sizes: 128, 192 and 256 bits. The Camellia specifications have
been published in full. Camellia was designed not only for high security
levels suitable for the next generation but also for high performance in
any target platform such as embedded systems, where low power consumption
is mandatory and server computers, where utmost speed is a top priority.
