RFC (part 1 of 5): Extensible Authentication Protocol Method for Global System for Mobile Communications (GSM) Subscriber Identity Modules (EAP-SIM ). EAP-SIM RFC is a newly emerged EAP authentication The standard for EAP-SIM authentication is still in draft form with the IETF . but are not limited to, RFCs, the products of another standards body (e.g. 3GPP ), EAP-AKA’ AT_KDF Key Derivation Function values; Trusted Non-3GPP 12, AKA-Notification and SIM-Notification, [RFC][RFC].

Used on fast re-authentication only.
Showing of 67 extracted citations. There have also been proposals to use IEEE Lightweight Extensible Authentication Protocol. Citation Statistics Citations 0 10 20 ’06 ’09 ’12 ’15 ‘ The 3rd generation AKA mechanism includes mutual authentication, replay protection, and derivation of longer session keys. In this document, the term nonce is only used to denote random nonces, and it is not used to denote counters.
Extensible Authentication Protocol
Archived from the original on EastlakeJeffrey I. Key distribution Cryptography Session key Documentation. EAP is not a wire protocol ; instead it only defines message formats. The client can, but does not have to be authenticated via a CA -signed PKI certificate to the server.
EAP-TLS is still considered one of the most secure EAP standards available, although TLS provides strong security epa 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 underlying key exchange is resistant to active attack, exp attack, and dictionary attack. Table of Contents 1. A proxy based authentication localisation scheme for handover between non trust-associated domains Mo LiKumbesan Sandrasegaran Mobile Computing and Communications Review Network Working Group H.
Authenticated Service Information for the…. The packet format and the use of attributes are specified in Section 8. The IETF has also not reviewed the security of the cryptographic algorithms. Fall Back to Full Authentication Targeting the weaknesses in static WEP”. The version negotiation is protected by including the version list and the selected version in the calculation of keying material Section 7. GSM cellular networks use a subscriber identity module card to carry out user authentication.
There are currently about 40 different methods defined. The EAP method protocol exchange is done in a minimum of four messages. It supports authentication techniques that are based on the following types of credentials:. Fast re-authentication is based on keys derived on full authentication. The authenticator typically communicates with an EAP server that is located on a backend authentication server using an AAA protocol. Since some cryptographic tfc may depend on the randomness of the nonce, attention should be paid to whether a nonce is required to be random or not.

Randomness Requirements for Security Donald E. Archived from the original on February 9, Archived from the original on 26 November Showing of 27 references. Second generation mobile networks and third generation mobile networks use different authentication and key agreement mechanisms.
The EAP-SIM mechanism specifies enhancements to GSM authentication and key agreement whereby multiple authentication triplets can be combined sjm create authentication responses and session keys of greater strength than the individual GSM triplets.
EAP is not a wire protocol; instead it only defines message formats. Distribution of this memo is unlimited. EAP-GTC carries a text challenge from the authentication server, and a reply generated by a security token. An introduction to LEAP authentication”.
EAP-AKA and EAP-SIM Parameters
Used on full authentication only. Skip to search form Skip to main content. This would allow 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 EAP is an authentication framework, not a specific authentication mechanism. Permanent Username The username portion of permanent identity, i. The protocol only specifies chaining multiple EAP mechanisms and not any specific method.
GSM authentication is based on a challenge-response mechanism. In particular, rvc following combinations are expected sjm be used in practice:. This vulnerability is mitigated by manual PAC provisioning or by using server certificates for the PAC provisioning phase.
This phase is independent of other phases; hence, any other scheme in-band or out-of-band can be used in the future. Microsoft Exchange Server Unleashed. Fast Sik Identity A fast re-authentication identity of sin peer, including an NAI realm portion in environments where a realm is used. Views Read Edit View history. In-band provisioning—provide the peer with a shared secret to be used in secure phase 1 conversation.
