Schlumberger
new security solution for W-LAN networks
Posted: 29 June 2003
Secure access and high speed are the differentiators of
the new W-LAN service Schlumberger will demonstrate at GSM Brazil
SchlumbergerSema, the information technology (IT) business segment
of Schlumberger Limited, announced it has launched a W-LAN (Wireless
Local Area Network) network solution with secure access through
its EAP-SIM smart card.
The solution, developed by Schlumberger, uses the EAP-SIM smart
card for user login authentication and was demonstrated at GSM Brazil
(June 26 to 27).
W-LAN networks offer high-speed access (11 Mbps) to Intranet and
Internet through radio frequency.
By using the EAP-SIM card for password authentication, the user
gains security for wireless communications.
With authentication criteria carried on the smart card itself rather
than stored on the server, the data is encrypted before it is sent
through the radio frequency, ensuring that mobile communications
achieve a high level of security.
The Schlumberger solution brings an important advancement to the
wireless market, where security over mobile networks has been elusive,
and one of the factors that should help expand usage of W-LAN networks
in the corporate environment.
Besides the card, Schlumberger has also developed the authentication
server and the gateway -- the user front door -- to complement the
W-LAN security card solution.
By using radio frequency for data access and transmission, the
Schlumberger W-LAN system does not require physical connections
for network installation.
This cost efficient and practical solution is ideal for companies
that operate in rented buildings or who have remote workers needing
access to the Internet or company Intranets from hotels, airports,
restaurants, or other public places once there are W-LAN hotspots
or antennae in place.
The complete W-LAN solution from Schlumberger aims to help mobile
services operators leverage the W-LAN market around three competencies:
capacity to authenticate clients; capacity to roam among networks;
and capacity to rate customers and roaming among partners.
The Schlumberger product portfolio will allow operators to provide
corporate customers with value-added services at competitive prices.
"Our expertise in smart cards, secure networking, IT and billing
solutions makes us the only player able to provide assistance in
all the critical areas for mobile services operators," said
Natália Fakhri, Schlumberger MobileCom marketing manager
for Latin America.
