Extensible Authentication Protocol, or EAP, is an authentication framework frequently used in EAP Transport Layer Security (EAP-TLS), defined in RFC , is an IETF open standard that uses the . EAP-AKA is defined in RFC .

For example, in IEEE Views Read 44187 View history. Used on full authentication only. It is more likely that the physical theft of a smart card would be noticed and the smart card immediately revoked than a typical password theft would be noticed. Format, Generation, and Usage of Peer Identities Pseudonym Username The username portion of pseudonym identity, i.

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. Dap cellular networks use a subscriber identity module card to carry out user authentication.

Extensible Authentication Protocol

These include the following: The authenticator typically communicates with an EAP server that is located on a backend authentication server using an AAA protocol. Archived from the original on February 9, Message Format and Protocol Extensibility It provides a protected communication channel, when mutual authentication is successful, for both parties to communicate and is designed for authentication over insecure networks such as IEEE This phase is independent of other phases; hence, any other scheme in-band or out-of-band can be used aep the future.

The encrypted data is not shown in the figures of this section. It is possible to use a different authentication credential and thereby technique in each direction. Network Working Group J. 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.


EAP Types – Extensible Authentication Protocol Types

Archived from the original PDF on 12 December In this document, both modules are referred to as identity modules. Because protected success indications are not used in this example, the EAP server sends the EAP-Success packet, indicating that the authentication was successful.

EAP is in wide use. 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.

Attacks against Identity Privacy AKA is based on challenge-response mechanisms and symmetric cryptography. Pseudonym Identity A pseudonym identity of the peer, including an NAI realm wap in environments where a realm is used.

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. The 3rd Generation AKA is not used in the fast re-authentication procedure.

Microsoft Exchange Server Unleashed. Vectors may be stored in the EAP server for use at a later time, but they may not be reused. The mobile network element that can authenticate subscribers in the mobile networks. In general, a nonce can be predictable e.

EAP is not a wire protocol; instead it only defines message formats. From the vector, the EAP server derives the keying material, as specified in Section 6. Targeting the weaknesses in static WEP”. PANA allows dynamic service provider selection, supports various authentication methods, is suitable for roaming users, and is independent from the link layer mechanisms.


Fast Re-Authentication Identity Akx fast re-authentication identity of the peer, including an NAI realm portion in environments where a realm is used. If the result is correct, IK and CK can be used to protect further communications between the identity module and the home environment. In certain circumstances, shown in Figure 4it is possible for the sequence numbers to get out of sequence.

After the server is securely authenticated to the client via its CA certificate and optionally the client to the server, the server can then use the established secure connection “tunnel” to authenticate the client.

This is a requirement in RFC sec 7. Protected success indications are discussed in Section rcf.

It is worth noting that the PAC file is issued on a per-user basis. It supports authentication techniques that are based on the following types of credentials:.

There have also aia proposals to use IEEE Archived from the original on 26 November The requirement for a client-side certificate, however unpopular it may be, is what gives EAP-TLS its authentication ea; and illustrates the classic convenience vs. Brute-Force and Dictionary Attacks Flooding the Authentication Centre In the 3rd generation mobile networks, AKA is used for both radio network authentication and IP multimedia service authentication purposes.
