EAP-SIM

This EAP authentication type uses the Subscriber Identity Module (SIM) used on Global System for Mobile (GSM) communications mobile networks. GSM is a secondgeneration mobile network standard. The SIM card, as it is fondly called, is a type of smart card that is distributed by the mobile network operators to their subscribers.

EAP-SIM was developed by the Third Generation Partnership Project (3GPP). The IETF document RFC 4186 describes EAP-SIM.

EAP-SIM builds on and extends the traditional GSM security mechanisms. It extends normal GSM authentication by providing a mechanism for the parties to authenticate each other mutually.
