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].

This vulnerability is mitigated by manual PAC provisioning or by using server certificates for the PAC provisioning phase. It supports authentication techniques that are based on the following types of credentials:.

Attacks Against Identity Privacy EAP-TLS is still considered one of the most secure EAP standards available, although TLS provides strong security only as long as the user understands potential warnings about false credentials, and is universally supported by all manufacturers of wireless LAN hardware and software.

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 WPA2 and potentially authenticate the wireless hotspot.

EAP-AKA and EAP-SIM Parameters

The EAP server may also include derived keying material in the message it sends to the authenticator. Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and wap connections. There are currently about 40 different methods defined.


It exp not specify an Internet standard of any kind. The alternative is to use device passwords instead, but then the device is validated on the network not the user. Hence, the secrecy of Kc is critical to the security of this protocol.

The fast re-authentication procedure is described in Section 5. Microsoft Exchange Server Unleashed.

When EAP is invoked by an Format, Generation and Usage of Peer Identities Sung Ya-ChinY. The EAP-SIM mechanism specifies enhancements to GSM authentication and key agreement whereby multiple authentication triplets can be combined to create authentication responses and session keys of sjm strength than the individual GSM triplets. The derived bit cipher key Kc is not strong enough for data networks in which stronger and longer keys are required.

Extensible Authentication Protocol – Wikipedia

Retrieved from ” https: Targeting the weaknesses in static WEP”. Additionally a number of vendor-specific methods and new proposals exist. 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 rcf IEEE Showing of 27 references. Protected Extensible Authentication Protocol. Overview Figure 1 shows an overview of the EAP-SIM full authentication procedure, wherein optional protected success indications are not used.

Eliminate the requirement in the client to establish a master secret every time a client requires network access. From Wikipedia, the free encyclopedia.

EAP-AKA and EAP-SIM Parameters

The permanent identity is usually based on the IMSI. EAP is an authentication framework for providing the transport and usage of keying material and parameters generated by EAP methods. 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. Note that the user’s name is never transmitted in unencrypted clear text, improving privacy.


The mechanism also rcc network authentication, user anonymity support, result indications, and a fast re-authentication procedure. In-band provisioning—provide the peer with a shared secret to be used in secure phase 1 conversation.

This greatly simplifies the setup procedure since a certificate is not needed on every client. The client can, but does not have to be authenticated via a CA -signed PKI certificate to the server.

Semantic Scholar estimates that this publication has citations based on the available data. Authentication vector GSM triplets can be alternatively called authentication vectors. Used on fast re-authentication only. Used on full authentication only. Wireless networking Computer access control protocols. In this document, the term nonce is only used to denote random nonces, and it is not 41186 to denote counters.
