+
+This is a small script that can be used with a PC-based smart card
+reader to obtain GSM/UMTS authentication parameters from a SIM/USIM
+card.
+
+== prerequisites ==
+
+We assume that you have
+
+* A smart card reader compatible with pcsc-lite
+* Installed python program and pyscard library
+
+
+=== smart card reader ===
+
+Any reader supported by pcsc-lite will work. However, a reader
+compatible with the USB CCID device class is much recommended.
+
+Please verify that the hardware and driver setup is working, e.g. by
+using the 'pcsc_scan' tool included with pcsc-lite. You should get an
+output like:

+}}}
+
+then your card was not detected in the reader.
+
+If you don't even get any displayed readers, your hardware and/or driver
+setup are likely wrong.
+
+
+=== pyscard ===
+
+pyscard can be installed from packages of major Linux distributions.
+
+If you want to build it from source, it is available from
+http://pyscard.sourceforge.net/
+
+
+== running osmo-sim-auth ==
+

+Options:

+ -a AUTN, --autn=AUTN AUTN parameter from AuC
+ -r RAND, --rand=RAND RAND parameter from AuC
+ -d, --debug Enable debug output
+ -s, --sim SIM mode (default: USIM)
+}}}
+
+you can run the program in two modes:
+ * running GSM authentication (classic SIM card protocol)
+ * running UMTS authentication (USIM card protocol)
+
+=== classic GSM authentication ===
+
+This mode will use the "RUN GSM ALGORITHM" command as specified in GMS
+TS 11.11
+
+You have to specify
+ * the 16 byte RAND value from the AuC (-r) as 32 hex digits
+ * the '-s' flag to enable SIM mode
+
+{{{

+GSM Authentication
+SRES: 215fdb4d
+Kc: 6de816a759a42912
+}}}
+
+=== UMTS authentication ===
+
+This mode will use the "AUTHENTICATE" command as specified in 3GPP TS
+31.102
+
+You have to specify
+ * the 16 byte RAND value from the AuC (-r) as 32 hex digits
+ * the 16 byte AUTN value from the AuC (-a) as 32 hex digits
+
+==== successful operation ====
+
+In this case, the tool will output the following values obtained from
+the card:
+ * RES authentication result value
+ * CK ciphering key
+ * IK integrity key
+ * Kc for inter-RAN handover from UMTS -> 2G
+
+Secondly, the tool will re-run the authentication in "2G authentication
+context" in order to obtain the SRES result. This value would be used
+if a 3G/2G dual-mode phone registers on a 2G network.
