Protection, Replay Ama, and Confidentiality The password may be a low-entropy one and may be drawn ep some set of possible passwords, like a dictionary, which is available to an attacker. 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 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 credentials, and is universally supported by all manufacturers of wireless LAN hardware and software.

The alternative is to use device passwords instead, but then the device is validated on the network not the user.

The permanent identity is usually based on the IMSI. In this document, the term nonce is only used to denote random nonces, rgc it is not used to denote counters. In addition to the full authentication scenarios described above, EAP-AKA includes a fast re-authentication procedure, which is specified in Section 5.

EAP Types – Extensible Authentication Protocol Types information

Eliminate the requirement in the client to establish a master secret every time a client requires network access. The packet format and the use of attributes are specified in Section 8. Protected Extensible Authentication Protocol.

This page was last edited on 21 Decemberat 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.

Note that the user’s name is never transmitted in unencrypted clear text, improving privacy. Archived from the original on In-band provisioning—provide the peer with a shared secret to be used in secure phase 1 conversation.

WPA2 and potentially authenticate the wireless hotspot. Table of Contents 1. 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. EAP-AKA includes optional identity privacy support, optional result indications, and an optional fast re-authentication procedure.

This vulnerability is mitigated by manual PAC provisioning or by using server certificates for the PAC provisioning phase. Permanent Username The username portion of permanent identity, i.

Extensible Authentication Protocol

Communicating the Peer Identity to the Server AKA works in the following manner: Vectors may be stored in the EAP server for use at a later time, but they may not be reused. Message Format and Protocol Extensibility It is possible to use a different authentication credential and thereby technique 417 each direction.


Message Sequence Examples Informative Requesting the Permanent Identity Protocol for Carrying Authentication for Network Access. EAP is not a wire protocol; instead it only defines message formats.

A value generated by the peer upon experiencing a synchronization failure, bits. The 3rd Generation AKA is not used in the fast re-authentication procedure. The authenticator typically communicates with an EAP server that is located on a backend authentication server using an AAA protocol.

The EAP method protocol exchange is done in a minimum of four messages. Terms and Conventions Used in This Document AKA is based on challenge-response mechanisms and symmetric cryptography.

From Wikipedia, the free encyclopedia. Brute-Force and Dictionary Attacks Fast Re-Authentication Username The username portion of fast re-authentication identity, i. The vector may be obtained by contacting an Authentication Centre AuC on the mobile network; for example, per UMTS specifications, several vectors may be obtained at a time.

Protected success indications are discussed in Section rdc. Figure 2 shows how the EAP server rejects the Peer due to a failed authentication.
