Background to the Joint
R&D
To realize e-governance and the ubiquitous environment listed in "e-Japan
Priority Policy Program", there is a pressing need to establish a fundamental
technology to realize a truly secure communication environment, and to support
the advanced information sharing society. Encryption and electronic authentication
are central to this technology."Secure and efficient implementation technology" is a vital R&D goal for achieving practical use. However, R&D has been faced with a trade-off between "security" and "efficiency". Therefore, Hitachi, Mitsubishi Electric and NTT launched the joint project and now they have succeeded in developing an implementation technology with the world's strongest security level while matching the efficiency of the existing products in the market. In March 2003, EU (European Union) approved NESSIE, a project to select the next-generation cryptographic algorithms. They selected "Camellia" jointly developed by Mitsubishi Electric and NTT, "MISTY1" by Mitsubishi Electric, and "PSEC-KEM" by NTT as recommended algorithms. Meanwhile, ISO (International Organization for Standardization) has been promoting the standardization of encryption goals by the Spring of 2004 at the earliest. In their deliberations, they have nominated not only "Camellia", "MISTY1" and "PSEC-KEM", but also "MULTI-S01" and "MUGI" by Hitachi, for international encryption standards. In addition, they have also been selected as recommended cryptographic algorithms by CRYPTREC: the cryptography evaluation project for e-governance by MPHPT (Ministry of Public Management, Home Affairs, Posts and Telecommunications) and METI (Ministry of Economy, Trade and Industry). Since the late 1990's, the U.S. and Japanese governments, EU and ISO, have actively promoted these encryption algorithm validation, selection, and standardization activities. They are now being almost completed, and the cryptographic algorithms that will be widely used in the first half of the 21st century are being listed up. The above Japanese cryptographic algorithm's excellent efficiency and their high commercial viability (LSI implementation) are highly regarded throughout these activities and it is likely that one or more of these Japanese company's algorithms will be widely used. Currently, ISO and CRYPTREC recognize that they need to emphasize "secure implementation", and they plan to establish the corresponding validation criteria and validation standards. As concern over "secure implementation of cryptosystems" increases, "CRESERC" is expected to be set into various application areas that require information security (for example, e-governance and ubiquitous communication systems) as the world's leading implementation technology in the field.
Hitachi, Mitsubishi Electric and NTT mutually
carried out this joint R&D by sharing their preeminent technology on
the basis of their shared advantage: the mathematical theory of elliptic
curve cryptosystems. Their roles are as follows:
These three companies plan to launch products
incorporating each company's preeminent technology in e-governance system
and ubiquitous-related security products based on their joint R&D results,
namely "CRESERC".

-- Hitachi, Ltd. (President: Etsuhiko Shoyama), Mitsubishi
Electric Corporation (President and CEO: Tamotsu Nomakuchi)
and Nippon Telegraph and Telephone Corporation (President:
Norio Wada) hereafter, Hitachi, Mitsubishi Electric and
NTT, respectively, announced their success in mutually
researching and developing an implementation technology
of an elliptic curve cryptosystem (ECDSA signature). They
named the technology "CRESERC". To establish this technology,
Hitachi, Mitsubishi Electric and NTT founded a project
team to research and develop a secure and efficient implementation
for elliptic curve cryptosystem (ECDSA signature). This
is the world's first case of well-established leaders
in the field of cryptography collaborating in the development
of implementation technology by integrating their advanced
skills and technologies.
