Nikkei English News, 24 September 1996.
Mitsubishi unveils Japan's fastest encryption chip
Mitsubishi Electric Corp. said it has developed an LSI
that can encrypt data at a speed of 450 megabits per
second, which is four times faster than any other
encryption chip developed in Japan and brings domestic
technology in line with DES, the U.S.-developed
encryption system that has become the standard in the
U.S. and Europe.
Because the chip performs the same as DES, Mitsubishi
will promote it as a domestic product for encryption
needs in Japan, with an eye on the growing market for
corporate intranets and high-speed data communications.
It said it will prepare for volume production during this
The company fabricated the chip as a gate array using a
0.5 micron CMOS process and its own proprietary
encryption algorithm MISTY. Operating at a maximum
input/output speed of 40 megahertz, the chip can handle
32 bits per clock cycle.
