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].

Key establishment to provide confidentiality and integrity during the rdc process in phase 2. It supports authentication techniques that are based on the following types of credentials:. Overview Figure 1 shows an overview of the EAP-SIM full authentication procedure, wherein optional protected success indications are not used.

Message Sequence Examples Informative Archived from the original on Pseudonym Username The username portion of pseudonym identity, i.

The IETF has also not reviewed the security of the cryptographic algorithms. GSM authentication is based on a challenge-response mechanism. If the MAC’s do not match, then the peer.

References Publications referenced by this paper. Attacks Against Identity Privacy Mutual Authentication and Triplet Exposure The alternative is to use device passwords instead, but then the device is validated on the network not the user.

Targeting the weaknesses in static WEP”. Authentication vector GSM triplets can be alternatively called authentication vectors. In-band frc the peer with a shared secret to be used in secure phase 1 conversation. It is possible to use a different authentication credential and thereby rgc in each direction. For example, in IEEE In particular, the following combinations are expected to be used in practice:.


Archived from the original PDF on ea December Permanent Username The username portion of permanent identity, i. Eliminate the requirement in the client to establish a master secret every time a client requires network access. Note that the user’s name is never transmitted in unencrypted clear text, improving privacy. Used on fast re-authentication only. Since 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.

Slm is not a wire protocol ; instead it only defines message formats.

This phase is independent of other phases; hence, any other scheme in-band or out-of-band can be used in the future. The EAP-SIM mechanism specifies enhancements to GSM authentication and key agreement whereby multiple authentication triplets can be combined to create authentication responses and session keys of greater strength than the individual GSM triplets. The packet format and the use of attributes are specified in Section 8. By using this site, you agree to the Terms of Use and Privacy Policy.

Extensible Authentication Protocol – Wikipedia

The EAP method protocol exchange is done in a minimum of four messages. GSM is a second generation mobile network standard. Archived from the original on 26 November Network Working Group H. WPA2 and potentially authenticate the wireless hotspot.


Permanent Identity The permanent identity of the peer, including an NAI realm portion in environments where a realm is used. Requesting the Permanent Identity This document frequently uses the following terms and abbreviations: The version negotiation is protected by including the version list and the selected version in the calculation of keying material Section 7. If the peer has maintained state information rfd fast re-authentication and wants to use fast re-authentication, then the peer indicates this by using a specific fast re-authentication identity instead of the permanent identity or a pseudonym identity.

The requirement for a client-side certificate, however unpopular it may be, is what gives EAP-TLS its authentication strength and illustrates the classic convenience vs.

PANA allows dynamic service provider selection, zim various authentication methods, is suitable for roaming users, and is independent from the link layer mechanisms. Message Format and Protocol Extensibility Archived from the original on February 9, Authenticated Service Information for theā€¦. 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
