RFC (part 1 of 5): Extensible Authentication Protocol Method for Global System for Mobile Communications (GSM) Subscriber Identity Modules (EAP-SIM ). EAP-SIM RFC is a newly emerged EAP authentication The standard for EAP-SIM authentication is still in draft form with the IETF . but are not limited to, RFCs, the products of another standards body (e.g. 3GPP ), EAP-AKA’ AT_KDF Key Derivation Function values; Trusted Non-3GPP 12, AKA-Notification and SIM-Notification, [RFC][RFC].

Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and point-to-point connections.

Used on full authentication only. Second generation mobile dap and third generation mobile networks use different authentication and key agreement mechanisms. By clicking accept or continuing to use the site, you agree to the terms outlined in our Privacy PolicyTerms of Serviceand Dataset License. Targeting the weaknesses in static WEP”. EAP is not a wire protocol; instead it only defines message formats. The derived bit cipher key Kc is not strong enough for data networks in which stronger and longer keys are required.

PANA allows dynamic service provider selection, supports various authentication methods, is suitable for roaming users, and is independent from the link layer mechanisms.

The GSM network element that provides the authentication triplets for authenticating the subscriber. The IETF has also not reviewed the ep of the cryptographic algorithms. The password may be a low-entropy one and may be drawn from some set of possible passwords, like a dictionary, which is available to an ffc.


This document frequently uses the following terms and abbreviations: The lack of mutual authentication in GSM has also siim overcome. GSM authentication is ffc on a challenge-response mechanism. In general, a nonce can be predictable e. This vulnerability is mitigated by manual PAC provisioning or by using server certificates for the PAC provisioning phase.

EAP-GTC carries a text challenge from the authentication server, and a reply generated by a security token.

EAP-AKA and EAP-SIM Parameters

Message Format and Protocol Extensibility After the server is securely authenticated to the client via its CA certificate and optionally the client to the server, the server can then use the established secure connection “tunnel” to authenticate the client.

Distribution of this memo is unlimited. It is possible to use a different authentication credential and thereby technique in each direction. The EAP method protocol exchange is done in a minimum of four messages.

The highest security available is when the “private keys” of client-side certificate are housed in smart cards. Archived from the original on 26 November Wireless networking Computer access control protocols.


The 3rd generation AKA mechanism includes mutual authentication, replay protection, and derivation of longer session keys. EAP-SIM also extends the combined RAND challenges and other messages with a message authentication code in order to provide message integrity protection along with mutual authentication.

This phase is independent rvc other phases; hence, any other scheme in-band or out-of-band can be used in the future.

Integrity and Replay Protection, and Confidentiality Permanent Username The username portion of permanent identity, i. There have also been proposals to use IEEE Showing of 67 extracted citations.

This would allow for situations much like HTTPS, where a wireless hotspot allows free access and does not authenticate station clients but station clients wish to use encryption IEEE Randomness Requirements for Security Donald E. The lack of mutual authentication is a weakness in GSM authentication. BlunkJohn R. Protocol for Carrying Authentication for Network Access. The mechanism also includes network authentication, user anonymity support, result indications, and a fast re-authentication procedure.
