Baltimore Technologies, AU-System and Gemplus Deliver World’s First Digital Signature Over Next Generation Wireless Networks

March 23, 2001

HANNOVER, Germany — Three leading wireless solution providers, Baltimore Technologies (NASDAQ:BALT – news; LSE:BLM.), AU-System (SSE:AUS.), and Gemplus (NASDAQ:GEMP – news), today announced the world’s first and most advanced security and authentication technologies featuring digital signatures over General Packet Radio Services (GPRS) networks.

This ground-breaking development in secure mobile commerce has been achieved in partnership with Ericsson, using the R520 handset, and will be demonstrated at the CeBIT trade show in Hannover, Germany from 22-28 March.

Security and bandwidth have been two critical success factors in the uptake of mobile commerce across the globe. GPRS provides at least four times greater bandwidth than typical GSM based connections and introduces core network changes in preparation for 3G networks. The new mobile commerce and business services require even greater security which is now being addressed jointly by Baltimore Technologies, AU-System and Gemplus.

E-security for mobile devices is provided by digital certificates, which are issued using a Wireless Public Key Infrastructure (WPKI) by network operators and content providers. These digital certificates are stored on the mobile devices using S/WIM (Subscriber Wireless Identity Module), the latest development in chip cards. The combination of WPKI and GPRS enables the provision of secure mobile services in the next generation mobile market.

According to Bo Albertson, Marketing Director Communications, Ericsson Mobile Communications, “Ericsson regards mobile e-commerce as one of the exiting new applications enabled by the combination of sufficient security level in the phone and the greatly enhanced data transmission rates offered by GPRS. This project gives powerful proof of the phone becoming a personal trusted device allowing for new exciting services and applications and we are very pleased to participate with the R 520 handset.”

“GPRS allows customers to access more data-enriched services with the added benefits of ‘always on, faster download’,” stated John Fallon, Director of Wireless at Baltimore Technologies. “This combined offering from three leading wireless solution providers makes available a comprehensive integrated security solution in tandem with the launch of 2.5G networks this year across the world.”

“This is a major break-through in wireless security, which is becoming increasingly important as GPRS and 3G networks are enabling new mobile applications,” says Christer Bjork, Business Area Manager at AU-System. “The solution is a great example of how AU-System, together with leading mobile vendors, can create viable solutions based on emerging technologies and enable a fast time-to-market.”

“The availability of secure and trusted solutions will be a major contribution to the success of m-commerce. Gemplus has leading experience in S/WIM cards and thanks to this partnership, takes wireless networks to new levels of security forging a Bond of Trust between consumers, financial institutions and mobile operators,” said Patrick Imbert, Mobile Commerce Director, Gemplus.

The solution has been developed based on cutting-edge technologies from a consortium of leading vendors within the mobile communications industry, Baltimore Telepathy wireless e-security from Baltimore Technologies, GemXploreTM Trust S/WIM cards from Gemplus and consultancy services from AU-System, to achieve a complete end-to-end security solution based on the latest WPKI and WIM standards

About GPRS

GPRS is a major step on the road towards 3G networks utilising an Internet Protocol IP backbone and packet based communication and thus is often referred to as 2.5G. Bandwidth is significantly greater than traditional GSM networks opening up a far greater range of services for mobile users, all of which require enhanced security. Such networks offer subscribers “always on” connectivity, eliminating repetitive and time-consuming reconnections making mobile intranet services possible, such access to corporate databases and resources on the move.
