Product Description:
SIM card is One consistent with GSM specifications "smart card", It is actually a chip card that contains the microprocessor, internal five modules, and each module corresponds to a function: CPU (8-bit), the program memory ROMR (3 ~ 8 kb), working memory RAM (6 ~ 16 kb), data memory EEPROM (128 ~ 256 kb) and serial communication unit. SIM card can achieve storage data (phone book, SMS, etc.) and in safe conditions (personal identification number PIN, the authentication key Ki correct) completion of customer identity authentication and encryption algorithms customer information process. These functions are microprocessor having aSIM card from the operating system is complete.
SIM card by the integrated circuit module and the plastic card body mass composition, in line with ISO7816 series of standards
SIM card chip embedded in the circuit board top, and then packaged into the card body inside
The card body material: ABS, PET/ PVC
SIM card can be classified by size: ID-1 cards and Plug-in Card .
GSM SIM Card important parameter Include :
1 .IMSI (15 digits ) ,2 .ICCID(20 digits ) 3. KI 4. SMSC . 5 MDN
2.Algorithm -A3&A8 ,COM 128-1 ,COM128-2 ,COM128-3
Above data can program with PC/SC Card Reader program .
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 the 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.
