RFC Extensible Authentication Protocol Method for Global System for Mobile Communications (GSM) Subscriber Identity Modules (EAP-SIM), January . 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 .

The highest security available is when the “private keys” of client-side certificate are housed in smart cards.

Information on RFC » RFC Editor

The standard also describes the conditions under which the AAA key management requirements described in RFC can be satisfied. The EAP method protocol exchange is done in a minimum of four messages. This 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.

Used on fast re-authentication only.

EAP-SIM, GSM Subscriber Identity Modules

Overview Figure 1 shows an overview of the EAP-SIM full authentication procedure, wherein optional protected success indications are not used. Mutual Authentication and Triplet Exposure A value that is used at most once or that is never repeated within the same cryptographic context. The lack of mutual authentication in GSM has also been overcome.

The EAP-POTP method provides two-factor user authentication, meaning that a rap-sim needs both physical access to a token and knowledge of a personal identification number PIN to perform authentication. EAP is an authentication framework, not a specific authentication mechanism. Format, Generation and Usage of Peer Identities Pseudonym Username The username portion of pseudonym identity, i.

Communicating the Peer Identity to the Server EAP-GTC carries a text challenge from the 416 server, and a reply generated by a security token. The password may be a low-entropy one and may be drawn from some set of possible passwords, like a dictionary, which is available to an attacker. The permanent ep-sim of the peer, including an NAI realm portion in environments where a realm is used.

The peer has derived the same keying material, so the authenticator does not forward the keying material to the peer along with EAP-Success. 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 Protocol for Carrying Authentication for Network Access.

Views Read Edit View history. 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. A pseudonym identity of the peer, including an NAI realm portion in environments where a realm is used. Used on full authentication only.

This greatly simplifies the setup procedure since a certificate is not needed on every client. EAP is an authentication framework for providing the transport and usage of keying material and parameters generated by EAP methods.

EAP-AKA and EAP-SIM Parameters

WPA2 and potentially authenticate the wireless hotspot. Cryptographic Separation of Keys and Session Independence Targeting the weaknesses in static WEP”. From the triplets, the EAP server derives the keying material, as specified in Section 7. It can eeap-sim 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 eap-si attack.

The GSM authentication and key exchange algorithms are not used in the fast re-authentication procedure. The IETF has also not reviewed the security of the cryptographic algorithms.

Hence, the secrecy of Kc is critical to the security of this protocol. For example, in IEEE Key establishment to provide confidentiality and integrity 4816 the authentication process in phase 2.

It does not specify an Internet standard of any kind.
