RFC Extensible Authentication Protocol Method for Global System for Mobile Communications (GSM) Subscriber Identity Modules (EAP-SIM), January . 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 .

It provides a protected communication channel, when mutual authentication is successful, for both parties to communicate and is designed for authentication over insecure networks such as IEEE Ea-psim peer has derived the same keying material, so the authenticator does not forward the keying material to the peer along with EAP-Success.

The username portion of fast re-authentication identity, i. Protected Extensible Authentication Protocol.

EAP-AKA and EAP-SIM Parameters

The EAP server may also include derived keying material in the message it sends to the authenticator. Integrity and Replay Protection, and Confidentiality The requirement for a client-side certificate, however unpopular it may be, rcc what gives EAP-TLS its authentication strength and illustrates the classic convenience vs.

Protected success indications are discussed in Section 6. From the triplets, the EAP server derives the keying material, as specified in Section 7.


EAP Types – Extensible Authentication Protocol Types

Overview Figure 1 shows an overview of the EAP-SIM full authentication procedure, wherein optional protected success indications are not used. GSM authentication is based on 486 challenge-response mechanism. The lack of mutual authentication in GSM has also been overcome. GSM is a second generation mobile network standard.

Wireless networking Computer access control protocols.

Retrieved from ” https: The IETF has also not reviewed the security of the cryptographic algorithms. Used on full authentication only. It is possible to use a different authentication credential and thereby technique in each direction. 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 Archived from the original on February 9, This phase is independent of other phases; hence, any other scheme in-band or out-of-band can be used in the future.

If the peer has maintained state information for fast re-authentication and wants to use fast re-authentication, then the 418 indicates this by using a specific fast re-authentication identity instead of the permanent identity or a pseudonym identity.

EAP-SIM, GSM Subscriber Identity Modules

It wap-sim co-developed by Funk Software and Certicom and is widely supported across platforms. EAP-GTC carries a text challenge from the authentication server, and a reply generated by a security token. PEAPv1 was defined in draft-josefsson-pppext-eap-tls-eap through draft-josefsson-pppext-eap-tls-eap[36] and PEAPv2 was defined in versions beginning with draft-josefsson-pppext-eap-tls-eap Mutual Authentication and Triplet Exposure A3 and A8 Algorithms Attacks Against Identity Privacy WPA2 and potentially authenticate the wireless hotspot.

Views Read Edit View history. Used in GSM to identify subscribers.

An introduction to LEAP authentication”. Communicating the Peer Identity to the Server Targeting the weaknesses in static WEP”. EAP is not a wire protocol; instead it only defines message formats.

A fast re-authentication identity of the peer, including an NAI realm portion in environments where a realm is used.
