strong security protocols for data privacy, integrity and network access control. Standards such as [802.1X], [IEEE 802.16e], [IKEv2], require the Extensible Authentication Protocol (EAP) [RFC 3748] as the framework for authentication purposes, with a mutual authentication between a client (supplicant, subscriber's terminal, VPN user) and an authentication server (AS). EAP methods MAY be implemented in smart cards. This draft describes a standard interface to EAP methods embedded in ISO7816 smart cards. These devices are generally considered as one of the most secure computing platform. As an illustration the NIST issued a set of specifications [NIST-PIV], dealing with the Personal Identity Verification (PIV) integrated circuit card. Annex one provides a reference example for a SIM based authentication [EAP-SIM]. Annex two gives a reference example for a MD5 based authentication. Annex three presents a reference example for a TLS based authentication [EAP-TLS]. Annex four describes the user's profile according to the ASN.1 [ASN.1] syntax. Annex five illustrates an MD5 authentication scenario that works with an EAP smartcard. Annex six shows ISO 7816 data exchanges with EAP-TLS smartcards. Annex seven presents ISO 7816 data exchanges with EAP- AKA [EAP-AKA] smart cards. Urien & All Informational Expires August 2009 [Page 5] EAP-Support in Smartcard February 2009 2 Relationships with RFC 3748 2.1 EAP multiplexing model According to [RFC 3748], EAP implementations conceptually consist of the four following components: 1- Lower layer. The lower layer is responsible for transmitting and receiving EAP frames between the peer and authenticator. EAP has been run over a variety of lower layers including - PPP; - Wired IEEE 802 LANs [IEEE-802.1X]; - IEEE 802.11 wireless LANs [IEEE-802.11]; - IEEE 802.16e Wireless Metropolitan LANs [IEEE-802.16e]; - UDP (L2TP [L2TP] and IKEv2 [IKEv2]) 2- EAP layer. The EAP layer receives and transmits EAP packets via the lower layer, implements duplicate detection and retransmission, and delivers and receives EAP messages to and from EAP methods. 3- EAP peer and authenticator layers. Based on the Code field, the EAP layer de-multiplexes incoming EAP packets to the EAP peer and authenticator layers. Typically, an EAP implementation on a given host will support either peer or authenticator functionality. 4- EAP method. EAP methods implement the authentication algorithms and receive and transmit EAP messages. Since fragmentation support is not provided by EAP itself, this is the responsibility of EAP methods. 2.2 EAP smartcards An EAP smart card implements one or several EAP methods, and works in cooperation with a Smartcard Interface Entity, that sends and receives EAP messages to/from this device. The simplest form of this interface is a software bridge that transparently forwards EAP messages to smart card.

The interface between EAP methods and the Peer-Layer is introduced in [RFC 4137] and comprises two main procedures: - methodState() initializes a method or gets its current state. This function is realized by two EAP-Smartcard procedures named SC.Reset- State and SC.Get-State. - eapReqData() forwards EAP messages to methods, and optionally returns a response. The EAP smartcard uses the SC.Process-EAP command for that purpose. Upon success, the method computes a set of values, whose use is more precisely defined in [EAP-KEY], and which are made available for other EAP layers: - The Master Session Key (MSK) used as a shared secret, involved in cryptographic material generation. The SC.Get-Session-Key command returns this value. - An additional key, the Extended Master Session Key (EMSK), never shared with a third party. This key is cached by the EAP-Smartcard. - Application Master Session Keys (AMSK) introduced by in [EAP-EXT] and obtained through a key distribution function (KDF) using EMSK and other values, as input parameters. This key is collected by the SC.Get-AMSK command. - Method-ID used as a unique identifier of an EAP conversation. It's typically obtained by the concatenation of two random values generated by server and client entities. This value is obtained via the SC.Get-Exported-Parameter command. - Server-ID corresponding to the identity, if any, of the server. For example it's the subject field of an X.509 certificate. This value is obtained via the SC.Get-Exported-Parameter command. - Peer-ID used for the identity of the client, if any. It could be the subject field of an X.509 certificate. This value is obtained via the SC.Get-Exported-Parameter command. Urien & All Informational Expires August 2009 [Page 8] EAP-Support in Smartcard February 2009 - Channel Bindings used as elements of information, typically relative to the IEEE 802.1x access point (Called-Station-Id, Calling-Station-Id, NAS-Identifier, NAS IP-Address, etc.). They are optionally mirrored during an EAP session, from server to client. This value is obtained via the SC.Get-Exported-Parameter command. 3.2 Other services An EAP-Smartcard has a physical interface with the EAP-Peer layer and produces output values as described in the previous section. However other management services are required for practical reasons: - Content Management. It's the set of operations needed to download credentials required by a particular method (X.509 certificates, cryptographic key,...). - Security Management. This service manages mechanisms (PIN code, biometric techniques,...) that restrict EAP-Smartcard use to authorized bearers. - Identity Management. When several methods are available, this service allows selecting one of them. 3.3 Out Of Band (OOB) facilities EAP sessions may tunnel protocols such as NAP (Network Access Protection) or NAC (Network Admission Control). It is likely that these transported messages will be encrypted and protected according to mechanisms managed by EAP methods. OOB facilities are services that enable Smartcard Interface Entities to exchange OOB messages (such as NAP or NAC) tunneled by smart card embedded EAP methods. 4 User's Identity The user's identity is a pointer to a tuple of values that comprises - The EAP-ID (the parameter returned in the EAP-Response Identity message), - The method type, - Credentials (certificates, private keys, shared secrets...) associated to this particular type. It may be of various types: - A network SSID as described in the 802.11 standard [IEEE 802.11]. - A user's identification (UserID) e.g. an ASCII string. A network access identifier, NAI [RFC 4282] may be used as UserID. - A pseudonym, e.g. a friendly name. Urien & All Informational Expires August 2009 [Page 9] EAP-Support in Smartcard February 2009 - Etc... 5 EAP smartcard services Mandatory services MUST be implemented in any smartcard that claims conformance with this draft. Optional services are not required by basic authentication operations. Secure services MAY be protected by a PIN code. Non secure services MUST be freely accessible. 5.1 Add-Identity Status: Optional. Security: Secure(ISSUER). The smartcard is initially manufactured without any user's identity. The personalization software or the Identity Management software, adds in the smartcard a user's identity that can be retrieved by other commands. 5.2 Delete-Identity Status: Optional Security: Secure(ISSUER) The smartcard contains a list of one or several user's identity that can be retrieved by the Identity Management software. The command deletes one entry of the identity list. 5.3 Get-Preferred-Identity Status: Optional Security: Non Secure. The smartcard contains at least one user's identity. The Identity Management software gets from the smartcard the initial and preferred user's identity. If the user has more than one identity, the Identity Management software uses the Get-Next-Identity to read all available identities. 5.4 Get-Current-Identity Status: Mandatory Security: Non Secure The smartcard contains at least one user's identity related to the user's network subscription. The Identity Management software gets from the smartcard its current user's identity. 5.5 Get-Next-Identity Status: Mandatory Security: Non Secure The smartcard may contain one or more user's identities according to the user's network subscriptions. The Identity Management software MAY prompt the user's identity and a subsequent selection allows the smartcard to process the appropriate EAP authentication type. The Urien & All Informational Expires August 2009 [Page 10] EAP-Support in Smartcard February 2009 Get-Next-Identity command allows the Identity Management software to read all the available user's identities. The Get-Next-Identity command MAY inform the Identity Management software when all user's identities have been read. Otherwise the Identity Management software detects the identity list end, when it gets again the first identity. 5.6 Set-Identity Status: Mandatory Security: Secure(BEARER) Once the Identity selection is processed, the Identity Management software needs to set the smartcard EAP framework, according to the selected user's identity. The Set-Identity sets the smartcard EAP state machine to the AUTHENTICATING state. 5.7 Get-Profile-Data Status: Optional Security: Secure(BEARER) The Identity Management software MAY request the subscriber's profile information. The Get-Profile-Data returns all related information available in the smartcard. Details of the subscriber's profile information are given in annex 4. The implementation of the information may be ruled by ASN.1 BER coding specification [ASN.1] or by an XML dialect [XML]. 5.8 Process-EAP Status: Mandatory Security: Secure(BEARER) The EAP process is described in the RFC 3748 specification and involves several EAP requests and responses packets, 1) EAP request/response Identity; 2) A suite of EAP request/response related to a particular authentication scenario; and 3) EAP success or failure. The Set-Identity restarts the smartcard EAP framework state machine for further processing using the EAP-Packets method. An incoming EAP/Request/Identity restarts the smartcard EAP framework state machine for further processing using other EAP- Packets methods. The smartcard receives RFC 3748 frames. It retrieves the appropriate EAP authentication type and its associated identifier. The smartcard maintains the EAP state machine and returns an EAP NAK packet if this state sequence is broken. In that case it reaches the NOT-AUTHENTICATED state. Urien & All Informational Expires August 2009 [Page 11] EAP-Support in Smartcard February 2009 Any EAP request is silently ignored if the state machine was not started. The last step of the protocol retrieves the Session Key from the smartcard. 5.9 Process-EAP-OOB Status: Optional. Security: Secure (BEARER) EAP method may tunnel Out Of Band messages used by protocols such as NAP or NAC. According to [RFC 4282] an EAP packet includes a length field that indicates the whole packet size. OOB data are appended to EAP packets, and their optional presence is implicitly notified by the use of the Process-EAP-OOB command. 5.10 Get-Session-Key Status: Mandatory. Security: Secure(BEARER) At the end of a successful authentication the Smartcard Interface Entity needs to update the appropriate crypto suite (if any) using the master session key (MSK). The Get-Session-Key returns MSK to the Smartcard Interface Entity. In the 801.1X context, MSK should be interpreted as the unicast key. In the 802.11i or WPA context MSK should be interpreted as the PMK (Pairwise Master Key). 5.11 Get-State. Status: Optional. Security: Secure(BEARER) This command returns the current smartcard state: 1) IDENTITY-NOT-SET, no user's identity has been selected. 2) AUTHENTICATING, an authentication session is in progress. 3) AUTHENTICATED, last authentication session was successful. 4) NOT-AUTHENTICATED, last authentication session failed. 5.12 Reset-State. Status: Optional. Security: Secure(BEARER) If the current state is IDENTITY-NOT-SET, this command has no effect. Urien & All Informational Expires August 2009 [Page 12] EAP-Support in Smartcard February 2009 Otherwise this command forces the EAP smartcard in the AUTHENTICATING state. 5.13 Method Functions Status: Optional. Security: Secure(BEARER) These facilities are dedicated to test issues and SHOULD BE forbidden in operational environments. The following services MAY be supported: -X509 Certificate storage -Random generator -Private key encryption -Private key decryption -Public key encryption -Public key decryption -Symmetric key encryption -Symmetric key decryption 5.14 Multiple EAP Identity selection Status: Optional. Security: Secure(BEARER) Multiple EAP authentications MAY be processed simultaneously in the same smartcard. If this capability is supported, the following rules apply: 1) Multiple EAP Identities MAY be selected at the same time. 2) Each selected EAP identity is associated with a short identifier returns by the Set-Identity command. The Smartcard Interface Entity software SHALL include this short identifier when necessary, in order to inform which of the selected EAP identities the command is targeted to. The smartcard software SHALL maintain a separate EAP state machine for each of the different selected EAP identities. 5.15 Get-Exported-Parameters Status: Optional. Security: Secure(BEARER) According to [EAP-KEY], EAP methods export a set of parameters that MAY be used by other EAP layers. In this draft, each attribute is identified by an index, and is read thanks to the Get-Exported- Parameter(index) command. Urien & All Informational Expires August 2009 [Page 13] EAP-Support in Smartcard February 2009 Six indexes are defined, that are associated to the following attributes: Index 1: Peer-ID. The peer identity authenticated by the EAP method. Index 2: Server-ID: It's the optional server identity, authenticated by the EAP method. Index 3: Method-ID. EAP method specifications deriving keys MUST specify a temporally unique method identifier known as the Method-ID. Index 4: Session-ID. The Session-ID uniquely identifies an EAP session between an EAP peer (as identified by the Peer-ID) and server (as identified by the Server-ID). Index 5: Key-Lifetime. While EAP itself does not support key lifetime negotiation, it is possible to specify methods that do. Index 6: Channel Bindings. Channel Bindings include lower layer parameters that are verified for consistency between the EAP peer and server. In order to avoid introducing media dependencies, EAP methods that transport Channel Binding data MUST treat this data as opaque octets. 5.17 Get-AMSK According to [RFC 4017] EMSK is an "additional keying material derived between the EAP client and server that are exported by the EAP method. The EMSK is at least 64 octets in length. The EMSK is not shared with the authenticator or any other third party. The EMSK is reserved for future uses that are not yet defined". It has been suggested in [EAP-EXT] to derive Application-specific Master Session Keys (AMSKs) from EMSK. As an illustration AMSK MAY be obtained by a Key Derivation Function (KDF), such as AMSK = KDF(EMSK, label, length) As pointed in [HOKEY-EMSK] "Different uses for keys derived from the EMSK have been proposed. Some examples include hand off across access points in various mobile technologies, mobile IP authentication and higher layer application authentication". This document introduces Specific Root Keys (USRK), and defines a special class of USRK, called a Domain Specific Root Key (DSRK); each DSRK is a root key used to derive Domain Specific Usage Specific Root Keys (DSUSRK). Urien & All Informational Expires August 2009 [Page 14] EAP-Support in Smartcard February 2009 EMSK / \ USRK DSRK / \ DSUSRK1 DSUSRK2 The USRK key derivation function is based on a pseudo random function (PRF) that has the following function prototype: KDF = PRF(key, data), key=EMSK and DSUSRK = KDF(DSRK, key label, optional data, length) In [WiMAX-Forum-Stage2] the Mobile IP Root Key (MIP-RK) is generated at the EAP-Authentication Server which is collocated with the HAAA and at the EAP-Peer located in the MS. MIP-RK = HMAC-SHA1(EMSK, "MIP APPLICATION ROOT KEY") The Get-AMSK(index, data) is a generic command, used to compute AMSK key, (as defined in [HOKEY-EMSK], [WiMAX-Forum-Stage2]) identified by an index and optionally associated to data, needed to its calculation. 6 Client and Server facilities EAP smartcard may offer two classes of services, - Client smartcards process EAP requests and returns EAP responses - Server smartcards process EAP responses and returns EAP requests 7 IEEE 802.16 services The [IEEE 802.16] security is based on the PKM (Privacy Key Management) protocol which requires, on the user's side, an X509 certificate and a private RSA key. [IEEE 802.16e] MAY support a version of PKM, referred as PKM-EAP, which at the end of authentication scenario, produces a MSK key, according to [RFC 3748] An IEEE 802.16 service is a couple of credentials (X509Certificate, Private RSA Key), associated to a given identification label, and therefore working with a particular EAP method. Two services are defined. 7.1 Get-Certificate Status: Optional. Security: Secure(BEARER) Urien & All Informational Expires August 2009 [Page 15] EAP-Support in Smartcard February 2009 This command reads the X509 certificate, associated with an identification label, which is either implicit or identified by an index. 7.2 Private-Key-Decryption Status: Optional. Security: Secure(BEARER) This command decrypts a message encrypted with the client public key, according to [PKCS1] 8 Relationships with the Smartcard Interface Entity. The Smartcard Interface Entity is a piece of software that establishes a logical bridge with smartcards. It MUST be able to detect a smartcard. If the device is not present, or if it silently discards an EAP message, then the Smartcard Interface Entity MUST reject all incoming request messages by the NAK code. 9 ISO 7816-4 APDUs This section of the document provides an implementation of the previous descriptions for ISO 78176-4 compatible smartcards. The section does not preclude of the transport protocol used between the smartcard and the reader. Thus, this specification does not mandate- to-implement any transport protocol such as T=0 or T=1, which are not in the scope of this document. It should be noticed that all values are in hexadecimal representation. Annexes of this document give implementation examples. Note: The class byte value defined in this section ('A0') SHALL be interpreted as an implementation example. Other values MAY be used respecting conventions, defined in ISO 78176-4. Urien & All Informational Expires August 2009 [Page 16] EAP-Support in Smartcard February 2009 9.1 ISO 7816 Status Word According to ISO 7816, the status word SW1, SW2 is a two bytes word, giving information about current operation either success or failure. '90' '00' indicates an operation success '98' '04' indicates one of the following events, - Access Condition not fulfilled, e.g. a pin code presentation is required. - Unsuccessful user PIN verification, at least one attempt left. '98' '40' indicates one of the following events - Unsuccessful user PIN verification, no attempt left - Smartcard blocked '9F' 'xx' indicates that xx bytes (mod 256) are ready for reading. - Operation result MUST be fetched by the ISO Get Response APDU (CLA = 'C0', P3= 'XX') '67' 'XX' - Incorrect parameter P3 '6B' 'XX' - Incorrect parameter P1 or P2 '6D' 'XX' - Unknown instruction code (INS) given in the command '6E' 'XX' - Wrong instruction class (CLA) given in the command '6F' 'XX' - Technical problem, not implemented... '61 ''XX' - Operation result MUST be fetched by the ISO Get Response APDU (CLA = 'C0', P3= 'XX') '6C ''XX' - Operation must be performed again, with the LE parameter value sets to 'XX'. '70' '00' - Packet silently discarded. '70' '01' - Authentication failure 9.2 Segmentation/Reassembly rules 9.2.1 Segmentation When a command transfers a payload, whose size is greater than 255 bytes, the less significant bit of the P1 byte is used as a More flag. - This bit is equal to zero for a non fragmented payload or a last fragment (More = 0 = False). - This bit is set to one (More = 1 = True) for a payload fragment. Urien & All Informational Expires August 2009 [Page 17] EAP-Support in Smartcard February 2009 See annexes for examples. 9.2.2 Reassembly - When a command reads less than 256 bytes, or in the last bloc case, the returned payload ends by the 9000 Status Word. - When a command returns more than 256 bytes, each payload bloc (except for the last one) ends by the 9yxx Status Word, in which xx indicates the length of the next bloc and y MAY have any value between 1 and F. The GET (INS=C0) command (A0C00000xx) is used to read the next bloc. - See annexes for examples. 9.3 PIN Management Some services require that the smartcard's bearer presents its PIN code. Smartcard returns the '98' '04' status word when it's necessary to check the PIN code, before accessing to a particular service (see previous section). A PIN code is typically a four/eight digits decimal number, ASCII encoded, and ranging between '0000' and '9999'. 9.3.1 Verify PIN +--------+-----+----------+----+----+----+----+ |Command |Class| INS | P1 | P2 | Lc | Le | +--------+-----+----------+----+----+----+----+ | Verify | A0 | 20 or 2A | 00 | 00 | 08 | 00 | +--------+-----+----------+----+----+----+----+ The ISO APDU Verify is used when a PIN code presentation is required.

If "multiple EAP Identity selection" is supported, P2 (AA value) shall indicate the short identifier associated with the selected EAP identity to which the command is targeted.

When the size of a returned EAP message is greater than the value indicated by the EAP length field, additional data should be interpreted as OOB messages. Success and failure packets do not imply any response. A success Status Word ('9000') shall be produced by the smartcard, when a "Success EAP packet" is processed. An alert status word ('7000') MAY be sent from the smartcard once a "Failure EAP packet" is received. EAP Identity packets are independent of the authentication type; this section of the document provides the packet details. The rest of the EAP packet being authentication protocol dependent, they are detailed in the informative annex of this document.

EAP packets are pushed in smart cards thanks to the EAP Authenticate command. For compatibility reasons, this command MAY be supported according to the following rules : - The Class byte is set to 0xA0 - The INS byte is set to 0x88 - The P1 byte is set to a NULL value - The P2 byte is not interpreted - The P3 byte is the segment length The [TS 102 310] standard works with implicit segmentation mechanisms. When an EAP request is greater than the maximum ISO 7816 size (255 bytes) it is fragmented in several segments whose size is less than 255. The first segment includes the packet length; therefore the transfer process is completed when the total length of exchanged data reaches this value. Here is a brief example. First Segment, A0 88 00 00 FF [segment 1] Other Segment, A0 88 00 00 FF [segment k] Last Segment, A0 88 00 00 xx [segment n] EAP-Length = P3-1 + P3-k +P3-n 9.14 Process-EAP-OOB This command has the same effects than Process-EAP, excepted that OOB data are concatenated to the incoming EAP message. +--------+-----+-----+----+----+----+----+ |Command |Class| INS | P1 | P2 | Lc | Le | +--------+-----+-----+----+----+----+----+ | | A0 | 80 | 00 | AA | XX | YY | +--------+-----+-----+----+----+----+----+ Lc indicates the ingoing EAP message length plus the OOB data size.

They are typically carried by one party (the end user, such as an employee or customer) but are controlled by another party (the issuer, such as an enterprise or service provider). Applications running on the Smart Card are controlled by the issuer, and serve to protect the interests of the issuer. 10.1 Security Claims Security claims expressed in this section are imported from [EAP-SC] Integrity Protection: no Replay Protection: no Confidentiality: yes (section 10.9.2) Key Derivation: yes (section 10.9.3) Key Strength: no Dictionary Attacks: yes (section 10.9.5) Fast Reconnect: no Cryptographic Binding: yes (section 10.9.6) Session Independence: no Fragmentation: no Channel Binding: yes (section 10.9.7) 10.2 Smart Card Technology The Smart Card consists of a microprocessor and non-volatile memory chipset enclosed in a physically tamper resistant module. This module is then embedded in a plastic card, or the module may be integrated into an alternative form factor, such as a USB device. 10.3 Tamper Resistant Storage and Execution Smart cards provide protective measures against physical and logical attacks against the processor and non-volatile memory. This enables the secure storage of end user cryptographic keys and user credentials, and secures execution of security sensitive operations such as encryption and digital signatures. The EAP-SC Authentication Method MUST store all secret cryptographic keys on the smart card in non-volatile memory. The EAP-SC Authentication Method MUST execute in the smart card all cryptographic functions that use stored secret cryptographic keys. Urien & All Informational Expires August 2009 [Page 30] EAP-Support in Smartcard February 2009 The EAP-SC Authentication Method MUST NOT export any secret cryptographic keys from the smart card. 10.4 Multi Factor Authentication Smart cards generally require a Smart Card handler to authenticate to the Smart Card in order to access data or application functionality. This makes it possible to enforce multi factor user authentication by combining something the user has (the smart card) with something the user knows (such as PIN) or is (Biometric authentication). The EAP Authentication Method MUST enforce the use of the user PIN or Biometric before user credentials may be accessed or used. 10.5 Random Number Generation Smart Cards generally contain a hardware based true random number generator independent of external or internal clocks and immune to outside interferences. The quality of the hardware generator is further enhanced by logical processing to ensure excellent statistical properties; and these properties are checked regularly on-board. The EAP Authentication Method MUST use the Smart Card Random Number Generator anywhere Random Numbers are required. 10.6 Cryptographic Capabilities Smart cards provide certified, built-in implementation and optimized execution of common cryptographic algorithms such as AES, DES, RSA, and ECC... The EAP Authentication Method MUST use the built-in Smart Card cryptographic capabilities for the execution of any cryptographic functionality. 10.7 Secure Provisioning Smart cards provide a secure method of provisioning credentials, applications and trusted network information from the issuer or service provider to the end user, and managing this information after the card has been issued. Smart cards support automated personalization (including card initialization, loading of card data and printing) enabling issuance in very large numbers. The EAP-SC Authentication method MUST implement support for pre- issuance personalization, as for example by supporting [GLOBAL PLATFORM] or similar functionality. The EAP-SC Authentication method SHOULD implement support for post-issuance card and application management. 10.8 Certification The processes for designing and manufacturing smart cards are subject to rigorous security controls. This makes possible the Urien & All Informational Expires August 2009 [Page 31] EAP-Support in Smartcard February 2009 certification of Smart Card functionality and applications by standardization organizations. The EAP-SC Authentication method MUST be implemented on a Smart Card platform that has been evaluated for security by a standards organization program such as [FIPS] or [COMMON CRITERIA]. 10.9 Smart Cards and EAP Security Claims EAP-SC enhances the security of Authentication Methods by enabling the enforcement of security policies on the End User platform. The overall security of EAP-SC is dependent on the security of the Authentication Method implemented on the Smart Card. The following section discusses certain EAP Security Claims and how they are enhanced by Smart Card security features. 10.9.1 Mutual Authentication Mutual authentication processes are generally based upon the use of random numbers. Smart Cards enhance the security of these processes by providing true random number generation. 10.9.2 Confidentiality Smart Cards improve the robustness of EAP messages encryption, by providing tamper resistant storage for the encryption keys and secure execution of the encryption algorithms. 10.9.3 Key Derivation Smart Cards improve the confidentiality of the key derivation process by providing tamper resistant storage for the master keys and secure execution of the key derivation algorithms. 10.9.4 Man-in-the-Middle Attacks Smart Cards improve security against Trojan Horse attacks by providing a logically tamper resistant environment for the full implementation of EAP methods and secure execution of the encryption algorithms. 10.9.5 Dictionary Attacks Smart Cards access is commonly protected via pin codes with a limited number of retries; permanent blocking of the device is enforced when the number of retries is exceeded. This mechanism provides enhanced protection against dictionary attacks aiming at discovering passwords. 10.9.6 Cryptographic Binding Urien & All Informational Expires August 2009 [Page 32] EAP-Support in Smartcard February 2009 Smart Cards provide tamper resistant storage for cryptographic keys and secure execution of the tunnel creation algorithms thus enhancing the cryptographic binding process. 10.9.7 Channel Binding Smart Cards can be used as a secure out of band distribution method for channel parameters and therefore enhance the channel binding process. 10.9.8 Protection Against Rogue Networks Smart Cards facilitate the provisioning and secure storage of information about trusted parties, such as the root certificates of trusted networks. This protects the end user against rogue networks and enables the enforcement of network roaming policies. 10.9.9 Authentication Method Security The overall security of EAP-SC is dependent on the encapsulated EAP- SC Authentication Method. Weaknesses in the underlying method, such as weaknesses in integrity protection, replay protection or key strength, are detrimental to the overall security. 11 Intellectual Property Right Notice To be specify according to the Author and Participants.

EAP-TLS smartcards securely store at least the following items - Client X509 certificate - Client Private RSA Key - Certification Authority Public Key According to the smartcard computing capacities, two modes are defined in this draft (see details in annex 6) - Mode 1: smartcard supports five functions : - Public Key Encryption, with the server public key - Private Key Encryption, with the client private key - Public Key decryption, with the Certification Authority (CA) public key - Reading of the client's certificate - Random Number Generator - Mode 2: smartcard fully processes the EAP-TLS protocol 14.1 Unix Time issue. As mentioned in [RFC 5216] TLS RFC the client hello message includes a 32 byte random number, whose first 4 bytes are interpreted as the Unix Time.

A single TLS record may be up to 16384 octets in length, but a TLS message may span multiple TLS records, and a TLS certificate message may in principle be as long as 16MB. The group of EAP-TLS messages sent in a single round may thus be larger than the maximum RADIUS packet size of 4096 octets, or the maximum 802 LAN frame size. Urien & All Informational Expires August 2009 [Page 39] EAP-Support in Smartcard February 2009 The chaining and extended length mechanisms identified in this document provide enough extension to manage incoming and outgoing EAP-TLS packets. Then, authenticator shall not necessary follow a specific fragment policy regarding whether EAP-TLS is provided by the smartcard or not. However, in order to prevent multiple segmentation and re-assembly operations, the maximum EAP message length of no fragmented packets issued by smartcard SHALL be set to an adapted value. As defined in EAP-TLS, when the smartcard receives an EAP-Request packet with the M bit set, it MUST respond with an EAP-Response with EAP-Type=EAP-TLS and no data.
