Extensible Authentication Protocol

EAP is not a wire protocol ; instead it only defines message formats. Permanent Username The username portion of permanent identity, i. Message Sequence Examples Informative Note that the user’s name is never transmitted in unencrypted clear text, improving privacy.

The mechanism also includes network authentication, user anonymity support, result indications, and a fast re-authentication procedure. Second generation mobile networks and third generation mobile networks use different authentication and key agreement mechanisms.

From Wikipedia, the free encyclopedia. Since some cryptographic properties may depend on the randomness of the nonce, attention should be paid to whether a nonce is required to be random or not. A3 and A8 Algorithms The IETF has also not reviewed the security of the cryptographic algorithms.

On full authentication, the peer’s response includes either the user’s International Mobile Subscriber Identity IMSI or a temporary identity pseudonym if identity privacy is in effect, as specified in Section 4. Distribution of this memo is unlimited. The lack of mutual authentication in GSM has also been overcome. The derived bit cipher key Kc is not strong enough for data networks in which stronger and longer keys are required. The fast re-authentication procedure is described in Section 5.

Key establishment to provide confidentiality and integrity during the authentication process in phase 2. The alternative is to use device passwords instead, but then the device is validated on the network not the user.

Protocol for Carrying Authentication for Network Access. Table of Contents 1. Traditionally a smart card distributed by a GSM operator.

The requirement for a client-side certificate, however unpopular it may be, is what gives EAP-TLS its authentication strength and illustrates the classic convenience vs. The username portion of permanent identity, eap-aim. 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.

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

The 3rd generation AKA mechanism includes mutual authentication, replay protection, and derivation of longer session keys.

Used on full authentication only. The EAP-POTP method provides two-factor user authentication, meaning that a user needs both physical access esp-sim a token and knowledge of a personal identification number PIN to perform authentication. Fast re-authentication is based on keys derived on full authentication. 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.

GSM cellular networks use a subscriber identity module card to carry out user authentication. Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and point-to-point connections. Protected Extensible Authentication Protocol. It was co-developed by Funk Software and Certicom and is widely supported across ffc. In general, a nonce can be predictable e. This is a requirement in RFC eeap-sim 7.

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

GSM is a second generation mobile network standard. This greatly simplifies the setup procedure since a certificate is not needed on every client.

EAP-AKA and EAP-SIM Parameters

A value that is used at most once or that is never repeated within the same cryptographic context. The GSM authentication and key exchange algorithms are not used in the fast re-authentication procedure. An introduction to LEAP authentication”.
