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

EAP Types – Extensible Authentication Protocol Types information

Requesting the Permanent Identity 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.

A pseudonym identity of the peer, including an NAI realm portion in environments where a realm is used. The Kc key is originally eapsim to be used as an encryption key over the air interface, but in this protocol, it is used for rfx keying material and is not directly used. The GSM network element that provides the authentication triplets for authenticating the subscriber. 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.

GSM authentication is based on a challenge-response mechanism. The peer has derived the eaps-im keying material, so the authenticator ewp-sim not forward eal-sim keying material to the peer along with EAP-Success. The permanent identity of the peer, including an NAI realm portion in environments where a realm is used.

This is a requirement in RFC sec 7. Fast Re-authentication Username The username portion of fast re-authentication identity, i. The username portion of permanent identity, i. Archived from the original on 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.

This phase is independent of other phases; hence, any rff scheme in-band or out-of-band can be used in the future. Ep-sim supports authentication techniques that are based on the following types of credentials:. The EAP method protocol exchange is done in a minimum of four messages. Integrity and Replay Protection, and Confidentiality Communicating the Peer Identity to the Server The username portion of pseudonym identity, i.

Protocol for Carrying Authentication for Network Access.

The protocol only specifies chaining multiple EAP mechanisms and not any specific method. When EAP is invoked by an The mechanism also includes network authentication, user anonymity support, result indications, and a fast re-authentication procedure.

Hence, the secrecy eqp-sim Kc is critical to the security of this protocol.
