Keynote Speech
Mr. Norio Wada
President and CEO, NTT
NTT Chief To Create Anti-Cyberterorrist Network

TOKYO (Nikkei)--Norio Wada, president of Nippon Telegraph and Telephone Corp. (9432), stressed in his keynote speech Tuesday at the Global Information Summit 2003 that it is important to build a telecommunications network invulnerable to a cyberterrorist attack.

The following are excerpts from his speech.

Although the arrival of the broadband era is being touted, there are still many hurdles to clear before we can transmit images and other data freely and safely. To cope with the situation, NTT crafted a new Internet strategy late last year.

The strategy seeks to create a next-generation network using fiber optics, dubbed Rena, by 2005. The Rena will be an interactive communications network, which boasts the quality and reliability of a fixed-telephone network as well as the flexibility and low cost of an Internet protocol network.

The Rena network can be connected with any electronic equipment, not to mention personal computers and telephones, ensuring the safe transmission of voice, text and video data.

The fiber optic network, in which communications speed is not influenced by distance, is the most suitable means for interactive communications. ADSL (asymmetrical digital subscriber line) is not good enough because of the slow speed it sends data.

There are two big problems with the existing Internet protocol network, however: The possible cutoff of communications in the case of a disaster or a cyberterrorist assault.

The Rena network will overcome these defects, however. It will be equipped with a system to prevent the invasion of malicious worms into the network, when it is assaulted by cyberterrorists, by automatically tracing the sender.
