3 firms develop next-generation encryption technology.

TOKYO, July 28 Kyodo

Hitachi Ltd., Mitsubishi Electric Corp. and Nippon Telegraph and Telephone Corp. (NTT) said Monday they have jointly developed a next-generation encryption technology for exchanging electronic data and documents.

The companies said they developed an implementation technology of an elliptic curve cryptosystem, which features more greatly enhanced security functions than the current systems and is expected to be a standard for e-governance and e-commerce in Japan in the future.

The elliptic curve cryptosystem utilizes mathematical operations over elliptic curves and encrypts data using short key lengths at high efficiency while maintaining a high level of security.

The three firms said it was the world's first success in developing an implementation technology in the field of cryptography by integrating advanced skills and technologies of leading high-tech companies.
