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 .

Lightweight Extensible Authentication Protocol. In addition, the private key on a smart card is typically encrypted using a PIN that only the owner of the smart card knows, minimizing its utility for a thief even before the card has been reported stolen and revoked. A fast re-authentication identity of the peer, including an NAI realm portion in environments where a realm is used. The EAP server may also include derived keying material in the message it sends to the authenticator. The protocol only specifies chaining multiple EAP mechanisms and not any specific method.
Wireless networking Computer access control protocols. The version negotiation is protected by including the version list and the selected version in the calculation of keying material Section 7.
EAP-AKA and EAP-SIM Parameters
Because protected success indications are not used in this example, the EAP server sends the EAP-Success packet, indicating that the authentication was successful. The derived bit cipher key Kc is not strong enough for data networks in which stronger and longer keys are required. Archived dap-sim the original PDF on 12 December Archived from the original on 26 November Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and point-to-point connections.
It provides a protected communication channel, when mutual authentication is successful, for fap-sim parties to communicate and is designed for authentication over insecure networks such as IEEE EAP-GTC carries a text challenge from the authentication server, and a reply generated by a security token. EAP is in wide use. In particular, the following combinations are expected to be used in practice:.
The packet format and the use of attributes are specified in Section 8. If the MAC’s do not match, then the peer. Used on full authentication only.
Microsoft Exchange Server Unleashed. An introduction to LEAP authentication”. Rvc Kc key is originally intended to be used as an encryption key over the air interface, but in this protocol, it is used for deriving keying material and is not directly used. The fast re-authentication procedure is described in Section 5. If the peer has maintained state information for fast re-authentication rap-sim wants to use fast re-authentication, then the peer indicates this by using a specific fast re-authentication identity instead of the permanent identity or a pseudonym identity.
Distribution of this memo is unlimited. The 3rd generation AKA mechanism includes mutual authentication, replay protection, and derivation of longer session keys.
After the fap-sim 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. It is possible to use a different authentication credential and thereby technique in each direction. It can use an existing and widely deployed authentication protocol and infrastructure, incorporating legacy password mechanisms and authentication databases, while the secure tunnel provides protection from eavesdropping and man-in-the-middle attack.
Archived from the original on 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 attacker. The lack of mutual eap-siim is a weakness in GSM authentication. Permanent Username The username portion of permanent identity, i.
Requesting the Permanent Identity Rfx greatly simplifies the setup procedure since a certificate is not needed on every client. Views Read Edit View history. For example, in IEEE PANA allows dynamic service provider selection, supports various authentication methods, is suitable for roaming users, and is independent from the link layer mechanisms. Format, Generation and Usage of Peer Identities The permanent identity is usually based on the IMSI.
Used on full authentication only. WPA2 and potentially authenticate the wireless hotspot.
EAP-SIM, GSM Subscriber Identity Modules
The GSM authentication and key exchange algorithms are not used in the fast re-authentication procedure. Permanent Identity The permanent identity of the peer, including an NAI realm portion in environments where a realm is used. Pseudonym Identity A pseudonym identity of the peer, including an NAI realm portion in environments where a realm is used.
The standard also describes the conditions under which the AAA key management requirements described in RFC can be satisfied.
