1. Introduction to Radiator SIM Module

This document describes how to install and configure the Radiator SIM Module.

Radiator SIM Module provides EAP-SIM (Extensible Authentication Protocol - Subscriber Identity Module), EAP-AKA (Extensible Authentication Protocol - Authentication and Key Agreement), and EAP-AKA' (Extensible Authentication Protocol - Authentication and Key Agreement Prime) support for Radiator RADIUS server. RADIUS is the de facto standard protocol for authenticating users and recording accounting information for wired and wireless LAN (Local Area Network)s. It is supported and used by most vendors, such as Cisco, Ericsson, Huawei, Juniper, Ruckus, Aruba, and Alcatel-Lucent.

Radiator SIM Module includes the following features:

3GPP AAA (Authentication, Authorisation, Accounting) Server SWm, S6b, SWa, and STa Diameter interfaces
For more information about Radiator 3GPP AAA Server, see Radiator 3GPP AAA reference manual .
IMSI privacy as defined by Wireless Broadband Alliance technical specification 'IMSI Privacy Protection for Wi-Fi'
3GPP Diameter SWx, Cx and Wx interfaces for direct HSS (Home Subscriber Server) connections
M3UA (MTP Level 3 User Adaptation Layer)/SIGTRAN interface for MAP (Mobile Application Part)-based authentication
MAP-based authorisation with UpdateGprsLocation and UpdateLocation operations for fetching MSISDN and other profile information
Support for converting AKA (Authentication and Key Agreement) vectors to SIM (Subscriber Identity Module) triplets
Support for MAP/SS7 (Signalling System No. 7) gateways for connecting to legacy AuC (Authentication Centre)/HLR (Home Location Register) servers over MAP, SIGTRAN, and other protocols
Support for full RADIUS accounting
Support for both IPv4 and IPv6
TCP (Transmission Control Protocol) and SCTP (Stream Control Transmission Protocol) for both IPv4 and IPv6

EAP-SIM is an EAP (Extensible Authentication Protocol) authentication protocol, designed to be used with existing GSM mobile phone authentication systems and SIM cards for mobile phones. The EAP-SIM standard allows Wireless LAN users to authenticate access to a Wireless LAN network using a mobile phone SIM card.

EAP-AKA is an EAP authentication protocol for authentication and session key distribution. It is based to the AKA mechanism: challenge-response and symmetric cryptography. EAP-AKA' is a variant of EAP-AKA, it is used for accessing 3GPP services via non-3GPP access.
