The Internet is now an indispensable information infrastructure for organizations. The telecommunication infrastructure [e.g. ADSL (asymmetric digital subscriber line), cable TV, etc.] providing broadband network services offering multimedia data contents like movies and voice over the Internet has also become widespread. As a result, many important services are being provided on the Internet. At the same time, however, networks have experienced rapid increases in virus attacks and illegal accesses. Thus, broadband networks are in need of improved information security. “Security 3A,” which stands for “Authentication,” “Authorization,”and “Administration,” is a comprehensive approach to ensuring the security of broadband networks. It takes advantage of technologies such as encryption and authentication. Hitachi is currently engaged in the development of security 3A systems for the broadband era.
