28、ensible Authentication Protocol is a general authentication framework, which supports multiple authentication methods. EAP typically may run directly over data link layers such as PPP (see RFC 1661 6) or IEEE Std 802.1X-2004 7 and IEEE Std 802.11-1999 8. As described in RFC 3748 1, EAP implementatio
29、ns consist of three main components: A lower layer that is responsible for transmitting and receiving EAP frames between the peer and the authenticator. EAP has been run over a variety of lower layers (including PPP, IEEE 802 LANs, IEEE 802.11 WLANs, and L2TP (see RFC 2661 5). An EAP layer that rece
30、ives and transmits EAP packets via the lower layer, implements duplicate detection and retransmission, and delivers and receives EAP messages to and from EAP methods. EAP methods that implement the authentication algorithms and receive/transmit EAP messages via the EAP layer. ETSI ETSI TS 102 310 V9
31、.1.0 (2012-09)7Release 9 The UICC offers suitable possibilities for the implementation of some of these EAP methods in the peer side, since it provides the required protection of credentials and authentication algorithms. This is even more important when the following conditions apply: The authentic
32、ation methods require the usage of credentials that are stored in the UICC. For security reasons, these credentials are not to be revealed in clear in an unprotected peer environment (e.g. a laptop or mobile terminal). The present document defines the principles that shall be implemented in the UICC
33、 in order to enable that UICC applications may support one or more of these EAP methods. 5 Architecture 5.1 Architectural Principles The following architectural principles are applied: The authenticator is able to perform an EAP authentication process (using an specific EAP method) with a UICC appli
34、cation implementing this method. That means that the authentication is performed end-to-end between the authenticator and the UICC application. The peer is composed of several components: - The UICC EAP Framework provides information to the terminal about the existing UICC applications that provide
35、UICC EAP clients. - A UICC application provides one or more UICC EAP clients. - A UICC EAP client implements one specific EAP method.

37、 following EAP related Data Objects: Application EAP support types list: defining the EAP methods supported by the corresponding UICC application. Application EAP Dedicated File list: defining a list of Dedicated Files, each of them associated to one supported EAP method. Likewise, each EAP method i
38、s associated to one DF. Each of this DF are hereafter referred as DFEAP. Application EAP Label: Defining a user readable label defining the EAP clients.

42、 M Coding: Application EAP supported types list: - Contain a list of supported EAP type (as defined in RFC 3748 1) each of them coded in one byte except for expanded types that are coded on 8 bytes. EXAMPLE 1: An UICC application supporting EAP-MD5 (see RFC 3748 1) and EAP-TLS (see RFC 2716 3) provi
43、des the following “Application EAP supported types list“: square4 040Dcorresponding to EAP-MD5 (Type=4) and EAP-TLS (Type=13). Application EAP Dedicated Files list: - Contain a list of file identifiers of each DFEAPassociated to a particular supported EAP type. Each of them coded in two bytes. ETSI
44、ETSI TS 102 310 V9.1.0 (2012-09)9Release 9 EXAMPLE 2: Using the previous example, A DF 6D34 for EAP-MD5 and a DF 6D35 for EAP-TLS will result in the following EAP Dedicated Files list: square4 6D346D35. Application EAP label: - The application label is a DO that contains a string of bytes provided b
45、y the application provider to be shown to the user for information. 5.3 EAP-capable-application selection The terminal shall use the information in EFDIRfile if available to present the list of EAP-capable applications to the user or to any application that may request an EAP authentication. The ter
46、minal shall then select the corresponding EAP-capable-application to start an EAP authentication. Once selected, all EAP-Client state machines of the application are reset. 5.4 Key derivation It is possible for many EAP methods to derive key material after successful authentications. These keys may
47、be used for subsequent processes (e.g. for WEP encryption in IEEE Std 802.11-1999 8). Keys derived from an authentication shall be retrieved by the terminal by inspecting the file EFEAPKEYS. 5.5 Authentication Status The terminal may retrieve the authentication status of the EAP client in the select
48、ed UICC application by inspecting the mandatory file EFEAPSTATUS. 6 EAP related Commands The following clauses specify the additional commands needed to implement the EAP framework in the UICC. 6.1 EAP Authenticate 6.1.1 Command description The function is used to transfer the EAP packets from the t
49、erminal to the selected UICC EAP client (i.e. EAP client in the selected UICC application that corresponds to the given EAP type). The UICC EAP client shall provide a response EAP packet (as defined in RFC 3748 1) or a warning status word according to the authentication method being used. The UICC EAP client shall maintain the state machine of the authentication process as described for the particular EAP method used. The function is related to a particular UICC application supporting
