Security scheme for high capacity USIM-based services

Research output: Contribution to journalArticlepeer-review


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, we defined the security models for each service that can be provided from high capacity USIM card and proposed eligible architectures and security schemes for internal storage of the smartcard. Consequently, the results of this study are expected to be widely applied to development of high capacity USIM and the related commercial services as a foundation technology or references.
