This vulnerability is mitigated by manual Aja provisioning or by using server certificates for the PAC provisioning phase. Archived from the original on 26 November Protected success indications are discussed in Section 6. The “home environment” refers to the home operator’s authentication network infrastructure. The permanent identity is usually based on the IMSI.

Extensible Authentication Protocol

EAP-TLS is still considered one of the most secure EAP standards available, although TLS provides strong security only as long as the user understands potential warnings about false a,a, and is universally supported by all rffc of wireless LAN hardware and software. Permanent Identity The permanent identity of the peer, including an NAI realm portion in environments where a realm is used. There have also been proposals to use IEEE Brute-Force and Dictionary Attacks By using this site, you agree to the Terms of Use and Privacy Policy.


Communicating the Peer Identity to the Server Additionally a number of vendor-specific methods and new proposals exist. It supports authentication techniques that are based on the following types of credentials:. The EAP server may also include derived keying material in the message it sends to the authenticator. The EAP method protocol exchange is done in a minimum of four messages.

EAP Types – Extensible Authentication Protocol Types information

EAP is not a wire protocol ; instead it only defines message formats. AKA works in the following manner: If this process is successful the AUTN is valid and the sequence number used to generate AUTN is within the correct rangethe identity eao produces an authentication result RES and sends it to the home environment.

The packet format and the use of attributes are specified in Section 8. Retrieved from ” https: EAP-GTC carries a text challenge from the authentication server, and a reply generated by a security token.

Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and point-to-point connections. Because 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.

In this document, both modules are referred to as identity modules.

Fall Back on Full Authentication Key establishment to provide confidentiality and integrity during the authentication process in phase 2.


Archived from the original on February 9, Fast Re-Authentication Username The username 4817 of fast re-authentication identity, i. It does not specify an Internet standard of any kind.

Flooding the Authentication Centre In this case, the identity module calculates a sequence number synchronization parameter AUTS and sends it to the network.

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. The encrypted data is not shown in the figures of this section. For example, in IEEE Vectors may be stored in the EAP server for use at a later time, but they may not be reused. The 3rd Generation AKA is not used in the fast re-authentication procedure. EAP is in wide use.

EAP is an authentication framework, not a specific authentication mechanism. The standard also describes the conditions under which the AAA key management requirements described in RFC can be satisfied. In general, a nonce can be predictable e. When EAP is invoked by an
