As the USIM technologies are evolving to include high speed CPU, mass storage devices, and high speed serial interfaces, various services are to be available through those technologies. The high capacity USIM card is a combination of IC card and high capacity flash memory. Because the flash memory does not provide security, additional protection technologies need to be incorporated for privacy issues and data protection. In this paper, the authors defined the security models for each service that can be provided from high capacity USIM card. Consequently, the results of this paper are expected to be widely applied to development of high capacity USIM and the related commercial services as a foundation technology or references.
