= GRcard SIM =
The GRcard SIM is a programmable GSM SIM card.
It uses a mixture of TS11.11 / ISO7816-4 and proprietary commands for programming
There is limited card programming support both in http://cgit.osmocom.org/cgit/pysim/ as well as the more interactive http://cgit.osmocom.org/cgit/cyberflex-shell/
== Command reference ==
To understand this reference, it is assumed that you are familiar with basic knowledge on smartcard
technologies, such as standard ISO 7816-3/-4 APDUs and GSM TS 11.11.
=== Setting the ICCID ===
Uses a standard UPDATE BINARY (D6) command on the EF.ICCID (2FE2)
Security: ADM2
=== Setting the IMSI ===
Uses a standard UPDATE BINARY (D6) command on the EF.IMSI (7F20/6F07)
Security: ADM2
=== Setting the Access Class ===
Uses a standard UPDATE BINARY (D6) command on the EF.ACC (7F20/6F78)
Security: ADM2
=== Setting the SMS Parameters ===
Uses a standard UPDATE RECORD (DC) command on the EF.SMS (7F10/6F42)
Security: ADM2
=== Setting the A3/A8 algorithm ===
Uses a standard UPDATE RECORD (DC) command on the non-standard (2700/6F70) EF
The record has a size of 1 byte and is defined as follows:
* 01 - COMP128v1
* 02 - COMP128v2
* 03 - COMP128v3
Security: ADM2
=== Setting the Ki ===
Uses a non-standard APDU {{{80 D4 02 00 10}}}, followed by 16 bytes of Ki
Security: none
=== Setting the PIN1 and PUK1 ===
Uses a non-standard APDU {{{80 D4 00 01 10}}} followed by 8 bytes of PIN1 and 8 bytes of PUK1
Security: none
=== Setting the PIN2 and PUK2 ===
Uses a non-standard APDU {{{80 D4 00 02 10}}} followed by 8 bytes of PIN2 and 8 bytes of PUK2
Security: none
=== Setting the ADM1 + AUK1 ===
Uses a non-standard APDU {{{80 D4 01 04 12 03 00}}} followed by 8 bytes of ADM1 and 8 bytes of AUK1
Security: none
=== Setting the ADM2 + AUK2 ===
Uses a non-standard APDU {{{80 D4 01 05 12 03 00}}} followed by 8 bytes of ADM2 and 8 bytes of AUK2
Security: none
=== Create File ===
Uses a non-standard APDU {{{80 CF 00 P2 LEN FID SIZE OPT1 ACC OPT2}}}, specified as follows:
* Parameter P2:
* 00: Create DF
* 01: Create linear record EF
* 02: Create transparent EF
* 03: Create cyclic record EF
* 04: used to create EF.0001 with size {{{0A20}}}
* FID: The 2 byte File ID
* SIZE: 2 bytes for the transparent EF size; or 1 byte for the number of records, and 1 byte for the record size for linear or cyclic EF
* OPT1: Always {{{0100}}}
* ACC: Access conditions (3 bytes), According to TS 11.11, Section 9.3
* OPT2: Always {{{FF}}}
In case a Directory or EF.0001 is created, OPT1, ACC and OPT2 are replaced with 8-bytes all-zero {{{00000000000000}}}
Security: ADM0
=== Erase Card ===
Uses a non-standard APDU {{{80FE000014 31323334353600001301FF0000000000000000EA}}}
Security: none
=== Authenticate as ADM0 ===
Uses a non-standard APDU {{{80 F6 00 00 08 PIN}}}, where per default PIN is {{{0000000000000000}}}
