Secure mobile tokens - the future
Secure mobile tokens are widely used in consumer products. The most popular one is the Subscriber Identity Module (SIM) security module used in GSM mobile phones. In the future, IUCC security modules would be used for 3G mobile phones. The use of secure mobile tokens in commercial environments besides mobile voice call and SMS-based services is still an emerging market. Existing security module technology will follow the technology roadmap in the near future and expand functionality and performance while still under heavy cost pressure in the consumer market. New technologies combining existing services or integrating standard Internet protocols would show up and allow for new devices and scenarios based on advance secure mobile tokens like secure multimedia card (SMMC) or secured FLASH disks. The success story of the SIM technology in GSM mobile networks is currently followed by UICC and USIM technology in 3G networks and plans exist to make use of secure mobile tokens for securing WLAN access and usage as well as to make use of it for general heterogeneous network access, regardless of it being DSL, fixed line, GSM, WLAN or Universal Mobile Telecommunications Systems (UMTS).
