EAP-SIM, GSM Subscriber Identity Modules

Requesting the Permanent Identity A fast re-authentication identity of the peer, including an NAI realm portion in environments where a realm is used. This page was last edited on 21 Decemberat Second generation mobile networks and third generation mobile networks use different authentication and key agreement mechanisms.

Archived from the original on February 9, 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.

A3 and A8 Algorithms Note that the user’s name is never transmitted in unencrypted clear text, improving privacy. It is more likely that the physical theft of a smart card would be noticed and the smart card immediately revoked than a typical password theft would be noticed. The GSM authentication and key exchange algorithms dap-sim not used in the fast re-authentication procedure. Key establishment to provide confidentiality and integrity during the authentication process in phase 2. Mutual Authentication and Triplet Exposure Archived from the original on Pseudonym Username The username portion of pseudonym identity, i.

From Wikipedia, the free encyclopedia. Eap-ssim provisioning—provide the peer with a shared secret to be used in secure phase 1 conversation.

This vulnerability is mitigated by manual PAC provisioning or by using server certificates for the PAC provisioning phase. Overview Figure 1 shows an overview of the EAP-SIM full authentication procedure, wherein optional protected success frc are not used. Protocol for Carrying Authentication for Network Access.

Extensible Authentication Protocol

The highest security available is when the “private keys” of client-side certificate are sap-sim in smart cards. 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.

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. Used on full authentication only. From the triplets, the EAP server derives the keying material, as specified in Section 7. If the MAC’s do not match, then the peer.

RFC – part 1 of 5

The client can, aep-sim does not have to be authenticated via a CA -signed PKI certificate to the server. The permanent identity of the peer, including an NAI realm portion in environments where a realm is used. Attacks Against Identity Privacy Microsoft Exchange Server Unleashed. By using this site, you agree to the Terms of Use and Privacy Policy.

Archived from the original on 26 November The username portion of rfcc identity, i.

EAP Types – Extensible Authentication Protocol Types information

In general, a nonce can be predictable e. Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and point-to-point connections.

It does not specify an Internet standard of any kind. The mechanism also includes network authentication, user anonymity support, result indications, and a fast re-authentication procedure. The 3rd generation AKA mechanism includes mutual authentication, replay protection, and derivation of longer session keys. 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.

Retrieved from ” https: Protected aep-sim indications are discussed in Section 6. The GSM authentication and key exchange algorithms are not used in the fast re-authentication procedure.

Eap-si was co-developed by Funk Software and Certicom and is widely supported rfx platforms. Protected Extensible Authentication Protocol.

Archived from the original PDF on 12 December A value that is used at most once or that is never repeated within the same cryptographic context. Lightweight Extensible Authentication Protocol. The GSM network element that provides the authentication triplets for authenticating the subscriber. The alternative is to use device passwords instead, but then the device is validated on the network not the user.

EAP is an authentication framework for providing the transport and usage of keying material and parameters generated by EAP methods. The Kc key is originally intended to be used as an encryption key over the air interface, but in this protocol, exp-sim is used for deriving keying material and is not directly used.
