Main characteristics of SIM card- Matching the standards of GSM11.11, GSM11.12, GSM11.14, GSM11.17.- Matching the standard of ISO7816.- Modularization design that is convenient to realize new functions.- Optimized file management system, which supports file access path selection.- STK data encrypt and checkout match the GSM03.48 standard absolutely.- Supporting the norm of the China mobile OTA2, the little assistant of no agony, mass storage telephone book, group sending short message etc.- Supporting inner backup mechanism to insure the data Integrality.- supporting T=0 transmission protocol, communication velocity supports 372/1 and 512/8.- Having the function that against inserting and pulling out of card when power on, and abnormal power off.
- Supporting the algorithm of DES, 3DES, COMP128-1 and have protection against attacking mechanism.
- Supporting the function of the circuitry encrypt and circuitry secrecy ,preventing communication data against being stolen or juggled unlawful .And it can be used to check out the data integrality.
- Agile individuation instructions not only insure they require of safety management but also can satisfy all kinds of customer’s requires of pluralistic STK functions.
- Perfect safety function and safety strategy, passed EAL4+safe authentication.
