Ann Arbor, MI — (press release excerpt) — Interlink Networks announced today that it has developed a wireless data authenticator based on the emerging Diameter protocol. This advanced implementation provides authentication, authorization, and accounting (AAA) functions in 3GPP2 wireless data networks. It is the first Diameter implementation available, and is designed for next generation mobile operators and OEMs for use in 3G wireless test labs.

Interlink Networks' AAA Diameter implementation is currently available on HP-UX and Linux platforms, and supports the Diameter base protocol and Mobile-IP application. Mobile operators, carriers, OEMs, and system integrators interested in utilizing this technology in their 3G wireless product development and testing labs should contact Interlink Networks for details on the company's Diameter Acceleration Program.

Diameter is an Internet protocol that supports seamless and continuous connectivity as mobile devices — such as PDAs, laptops, or cell phones with Internet data capabilities — move between service provider networks and change their points of attachment to the Internet. Using Diameter, the user is able to gain reliable access to the Internet, anytime and anywhere. Interlink Networks' Diameter implementation is essential in this environment because it authenticates the user, dynamically generates keys for securing registration messages, and utilizes specific features of the Diameter protocol.

Diameter offers wireless data service providers several advantages over the existing RADIUS AAA protocol, including better message transport, proxying, session control, and higher security for AAA transactions. Diameter was proposed as a standard at the IETF AAA Working Group in December 2001.
