Gemplus and TOGEWAnet present « WeRoam Enterprise Secure »

A smart card solution for both SIM based authentication and secure access to corporate domains via Public WLAN.

ITU Telecom World 2003, Geneva and Luxembourg, 9 October 2003 — Gemplus International S.A. (Euronext: LU0121706294 — GEM and NASDAQ: GEMP), the world’s leading provider of smart card based solutions and TOGEWAnet AG present WeRoam Enterprise Secure to provide access to Public WLAN using smart cards and client software. This solution is targeted at the enterprise market.

At ITU Telecom World 2003, Gemplus and TOGEWAnet will demonstrate how the SIM can manage user authentication to the Internet over Public WLAN, and then guide the user through to access the corporate Virtual Private Network (VPN) and Intranet.

Alex Mandl, CEO, Gemplus, said “WeRoam Enterprise Secure with TOGEWAnet is an exciting project for Gemplus as it clearly demonstrates how one card can manage the authentication to both the wireless network and the enterprise intranet. It promotes security for enterprises whose employees are often working away and is a new direction for the SIM.”

TOGEWAnet operates the solution themselves by providing the server infrastructure and acting as the SIM card issuer. Gemplus provides a solution including client software ensuring high security WLAN authentication via the EAP-SIM¹ protocol and strong VPN authentication via GemSAFE Libraries², a smart card reader and a SIM smart card.

Toni Stadelmann, CEO, TOGEWAnet, said, “As more and more enterprises enable their users to use Wireless technologies for anywhere anytime access to Corporate Systems over the Internet the need for centralized authentication, authorization and security increases. By combining the strengths of Gemplus in the field of smart card management and the knowledge and expertise of TOGEWAnet in the area of mobile communication we have been able to create an ideal solution which combines strong authentication and security in a Wireless environment. The cooperation with Gemplus has been very successful enabling us to produce the first joint secure service in less then four (4) months”.
