EAP Types – Extensible Authentication Protocol Types

From Wikipedia, the free encyclopedia. There have also been proposals to use IEEE EAP is an authentication framework, not a specific authentication mechanism. Message Format and Esp Extensibility If the peer has maintained state information for re-authentication and 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.

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

By using this site, you agree to the Terms of Use and Privacy Policy. Archived from the original on 26 November In addition to the full authentication scenarios described above, EAP-AKA includes a fast re-authentication procedure, which is specified in Section 5.

In this document, both modules are referred to as identity modules. Microsoft Exchange Server Unleashed. Terms and Conventions Used in This Document This document frequently uses the following terms and abbreviations.


Protection, Replay Protection, and Confidentiality The “home environment” refers to the home operator’s authentication network infrastructure. If the result is correct, IK and CK can be used to protect further communications between the identity module and the home environment. EAP-GTC carries a text challenge from the authentication server, and a reply generated by a security token.

The packet format and the use of attributes are specified in Section 8. PANA allows dynamic service provider selection, supports various authentication methods, is suitable for roaming users, and is independent from the link layer mechanisms.

Protocol for Carrying Authentication for Network Access. Table of Contents 1.

Archived from the original PDF on 12 December Permanent Identity The permanent identity of the peer, including an NAI realm portion in environments where a realm is used. If this process is successful the AUTN is valid and the sequence number used to generate AUTN is within the correct alathe identity module produces an authentication result RES and sends it to the home environment.

This would wap for situations much like HTTPS, where a wireless hotspot allows free access and does not authenticate station clients but station clients wish to use encryption IEEE In the 3rd generation mobile networks, AKA is used for both radio network authentication and IP gfc service authentication purposes.

AKA is based on challenge-response mechanisms and symmetric cryptography. R UIM is an application that is resident on devices such as smart cards, which may be fixed in the terminal or distributed by CDMA operators when removable.

Pseudonym Username The username portion of pseudonym identity, i. The EAP-POTP method provides two-factor user authentication, meaning that a user needs both physical access to a token and knowledge of a personal identification number PIN to perform authentication.

Used on re-authentication only. A value generated by the peer upon experiencing a synchronization failure, bits. On full authentication, the peer’s identity response includes either the user’s International Mobile Subscriber Identity IMSIor a temporary identity pseudonym if identity privacy is in effect, as specified in Section 4.


These include the following: EAP is in wide use. There are currently about 40 different methods defined. In this document, the term nonce is only used to denote random nonces, and it is not used to denote counters. GSM cellular networks use a subscriber identity module card to carry out user authentication.

This phase is independent of other phases; hence, any other scheme in-band or out-of-band can be used in the future.

Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and point-to-point connections. Arkko Request for Comments: Because some cryptographic properties may depend on the randomness of the nonce, attention should be paid to whether a nonce is required to efc random or not.

The EAP method protocol exchange is done in a minimum of four messages.

This is a requirement in RFC sec 7. In certain circumstances, shown in Figure 4it dap possible for the sequence numbers to get out of sequence. From the vector, the EAP server derives the keying material, as specified in Section 6. Note that the user’s name is never transmitted in unencrypted clear text, improving privacy.

EAP-AKA includes optional 4817 privacy support, optional result indications, and an optional fast re-authentication procedure. For example, in IEEE 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
