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 .

Table of Contents 1. If the peer has maintained state information for 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. Archived from the original PDF on 12 December In this document, the term nonce is only used to denote random nonces, and it is not used to denote counters.
EAP-AKA and EAP-SIM Parameters
Pseudonym Username The username portion of pseudonym identity, i. There are currently about 40 different methods defined. There have also been proposals to use IEEE The EAP method protocol exchange is done in a minimum of four messages. EAP-SIM also extends the combined RAND challenges and other messages with a message authentication code in order to provide message integrity protection along with mutual authentication.
GSM cellular networks use a subscriber identity module card to carry out user authentication. Rcf 3rd generation AKA mechanism includes mutual authentication, replay protection, and derivation of longer session keys.

Wireless networking Computer access control protocols. The IETF has also not reviewed the security of the cryptographic algorithms. Fall Back to Full Authentication Archived from the original on 26 November It is worth noting that eap-simm PAC file is issued on a per-user basis. Extensible Authentication Protocolor EAPis an authentication framework frequently used in wireless networks and point-to-point connections. The alternative is to use device passwords instead, but then the device is validated on the network not the user.
For example, in IEEE Used on full authentication only. GSM authentication is based on a challenge-response mechanism.
Extensible Authentication Protocol
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 document frequently uses the following terms and abbreviations: This is a requirement in RFC sec 7. Requesting the Permanent Identity The username portion of pseudonym identity, i. Flooding the Authentication Centre In-band provisioning—provide the peer ewp-sim a shared secret to be used in secure phase 1 conversation.
EAP is an authentication framework, not a specific authentication mechanism. The username portion of permanent identity, i. If the MAC’s do not match, then the peer. The protocol only specifies chaining ea-sim EAP mechanisms and not any specific method.
EAP is an authentication framework for providing the transport and usage of keying material and parameters generated by EAP methods. WPA2 and 416 authenticate the wireless hotspot.
EAP-AKA and EAP-SIM Parameters
The derived bit cipher key Kc ea-psim not strong enough for data networks in which stronger and longer keys are required. GSM is a second generation mobile network standard.
The lack of mutual authentication in GSM has also been overcome. The version negotiation is protected by including the version list and the selected version in the calculation of keying material Section 7. Retrieved from ” https: It was co-developed by Funk Software and Certicom and is widely supported across platforms.
The authenticator typically communicates with an EAP server that is located on a backend authentication server using an AAA protocol. The EAP-SIM mechanism specifies enhancements to GSM authentication and 418 agreement whereby multiple authentication triplets can be combined to create authentication responses and session keys of greater strength than the individual GSM triplets.
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.
