RFC Extensible Authentication Protocol Method for 3rd Generation Authentication and Key Agreement (EAP-AKA), January Canonical URL. 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 .

The 3rd Generation AKA is not used in the fast re-authentication procedure. EAP-AKA includes optional identity privacy support, optional result indications, and an optional fast re-authentication procedure. WPA2 and potentially authenticate the wireless hotspot. The highest security available is when the “private keys” of client-side certificate are housed in smart cards.

Targeting the weaknesses in static WEP”. Nonce A value that is used at most once or that is never repeated within ama same cryptographic context. Fast re-authentication is based on keys derived 4817 full authentication. 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.

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. In general, a nonce can be predictable e.

This would allow for situations much like HTTPS, where rf wireless hotspot allows free access and does not authenticate station clients but station clients wish to use encryption IEEE Used on full authentication only. Permanent Username The username portion of permanent identity, i. Epa 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.

Attacks against Identity Privacy An introduction to LEAP authentication”.

PANA allows dynamic service provider selection, supports various authentication methods, is suitable for roaming users, and is independent from the link layer mechanisms. 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.

The “home environment” refers to the home operator’s authentication network infrastructure. Table of Contents 1.

RFC – part 1 of 4

Permanent Identity The permanent identity of the peer, including an NAI realm portion in environments where a realm is used. Retrieved from ” https: EAP is an authentication framework, not a specific authentication mechanism. This document frequently uses the following terms and abbreviations.

Fast Re-Authentication Identity A fast re-authentication identity of the peer, including an NAI realm portion in environments where rcf realm is used. Network authentication fails The AKA uses shared secrets between the Peer and the Peer’s home operator, together with a sequence number, to actually perform an authentication.

Protocol for Carrying Authentication for Network Access. It is worth noting that the PAC file is issued on a per-user basis. AKA is based on challenge-response mechanisms and symmetric cryptography.

This greatly simplifies the setup procedure since a certificate is not needed on every client. The alternative is to use device passwords instead, but then the device is validated on the network not the user. The protocol only specifies chaining multiple EAP mechanisms and not any specific method. Microsoft Exchange Server Unleashed. Communicating the Peer Identity to the Server The permanent identity is usually based on the IMSI.

In this case, the identity module calculates a sequence number synchronization parameter AUTS and sends it to the network. In addition to the full authentication scenarios described above, EAP-AKA includes a fast re-authentication procedure, which is specified in Section 5.

Extensible Authentication Protocol

When verifying AUTN, the identity module may detect that the sequence number the network uses is not within the correct range. Requesting the Permanent Identity The peer has derived the same keying material, so the authenticator does not forward the keying material to the peer along with EAP-Success.

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 akq of the permanent identity or a pseudonym identity.
