TOKYO, March 10, 2000-----Nippon Telegraph and Telephone Corporation (NTT)
and Mitsubishi Electric Corporation (Mitsubishi) announced today their joint
development of "Camellia," a next-generation symmetric-key encryption
algorithm (*1).
Next-generation symmetric-key encryption algorithms with high security and
efficiency on various platforms are indispensable for ensuring the secrecy
of corporate and individual private information in the advanced information
society.
The new next-generation encryption algorithm Camellia is a symmetric-key
encryption algorithm with a block size (*2) of 128 bits. It was developed by
NTT and Mitsubishi using NTT's cipher design technologies geared to high
speed software implementation, Mitsubishi's cipher design technologies for
compact and high-speed hardware implementation, and state-of-the-art
security evaluation technologies of both companies.
Camellia was designed to ensure security in usage for more than 20 years and
to provide high speed in software and hardware implementation as well as
compactness of hardware chips. Camellia therefore provides world's highest
level performance in terms of efficiency and practicality on various
platforms.
