2 Overview
All wireless LAN technologies derived from IEEE 802.11 or IEEE
802.16 specifications, need strong security protocols for data
privacy, integrity and network access. The 802.1X specification
describes the risks and the protocols for the protection of the
exchanged data during the network connection.
802.1X specification requires the Extensible Authentication Protocol
(EAP) to be used as the framework for application dependent
authentication processes with a mutual authentication between the
supplicant and the authenticator. It is obvious that the role of the
supplicant in this specification could partly be implemented in the
smartcard as an authentication processing mean. The flexibility of
EAP [RFC 3748] specification does not provide a Mandatory-to-
Implement solution. The structure of the EAP frames allows the
applications to identify the EAP type of consequently to operate the
appropriate authentication.
This draft describes a standard interface to an EAP implementation
embedded in a smartcard. This device is generally considered as the
most secure computing platform.

4 Relationship with RFC 3748
4.1 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];
- UDP (L2TP and ISAKMP)
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 demultiplexes 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.
4.2 EAP smartcards
An EAP smartcard implements an EAP method and works in cooperation
with a smartcard interface entity, that sends and receives EAP
messages to/from this component. The simplest form of this interface
is a software bridge that forwards EAP messages to smartcard.
According to EAP methods complexity and smartcard computing
capacities, protocols sub-sets, that don’t deal with security
features may be computed by the smartcard interface entity.

5 Identification label
802.1X specification [IEEE 801.1X] requires an authentication
between the authentication server (AS) and the supplicant. The
authentication is embedded in the Extensible Authentication Protocol
(EAP) [RFC 3748] specification. The authentication consists of a
challenge response between both parties, without consideration of
the involved crypto-suite. Before starting the mutual
authentication, the AS needs the supplicant identity to establish
the session. The AS or the authenticator sends an EAP Request
Identity to the supplicant that returns its system identity. A user
may own several identities associated to corporate, personal
networks or operators' networks.
The identification label is a pointer to a system identity (the EAP-
ID value returned in the EAP-Identity.response message) stored in
smartcard; it may be of various types:
1. A network SSID as described in the 802.11 standard [IEE 802.11].
2. A user's identification (UserID) e.g. an ASCII string (as
described in section 6). A network access identifier, NAI [RFC 2486]
may be used as UserID.
3. A pseudonym, e.g. a friendly name.

According to the network environment, the supplicant software needs
to set the appropriate identity
The subsequent sections give the description of the methods used by
a supplicant for processing an 802.1X authentication using the
smartcard.
Annex one provides a reference implementation example for a SIM
based authentication. Annex two provides a reference implementation
example for a MD5 based authentication. Annex three provides a
reference implementation for a TLS based authentication. 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 smartcards.
6 UserID Coding Rules
This section describes the structure and the architecture of the
UserID.
A UserID consists of 2 fields separated by the Internet symbol "@".
The right hand side of the "@" symbol is the UserID realms while the
left hand side is an application dependent and unique identification
number.
EAP/SIM has defined the UserID where the application identification
is "1IMSI". Other UserID such as eMail address can be used by the
application.
7 Secure, non-Secure, mandatory and optional 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 are protected by a PIN code. Non secure services
MUST be freely accessible.
7.1 Add-Identity
Status: Optional.
Security: Secure(ISSUER).
This command and the Delete-Identity are part of the user's identity
management protocols. The smartcard is initially manufactured
without any identification label. The personalization or the
supplicant software adds in the smartcard user's identification
label that can be retrieved by other smartcard command.
7.2 Delete-Identity
Status: Optional
Urien & All Informational - Expires April 2006 8
EAP-Support in Smartcard October 2005
Security: Secure(ISSUER)
This command and the add-Identity are part of the user's identity
management protocols. The smartcard contains a list of one or
several identification labels that can be retrieved by the
supplication software. The command deletes one entry of the
smartcard list.
7.3 Get-Preferred-Identity
Status: Optional
Security: Secure(BEARER)
The smartcard contains at least one user's identity. The supplicant
software gets from the smartcard the initial and preferred
identification label. If the user has more than one identity the
supplicant software uses the Get-Next-Identity to read all the
available other user's identities.
7.4 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 supplicant software gets from the
smartcard its current identification label.
7.5 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 supplicant software should
prompt the user's identity and a subsequent selection allows the
smartcard to process the appropriate EAP authentication type. The
method Get-Next-Identity allows the supplicant software to read all
the available user's identities.
The Get-Next-Identity method may inform the supplicant software when
all user's identities have been read. Otherwise the supplicant
software detects the identity list end when it gets again the first
identity.
7.6 Get-Profile-Data
Status: Optional
Security: Secure(BEARER)
The Authentication Agent or the authenticator may request the
subscriber profile information. The Get-Profile-Data returns all
related information available in the smartcard. Details of the
subscriber profile information are given in annex 4. The
implementation of the information may be ruled but ASN.1 BER coding
specification [ASN.1] or by an XML dialect [XML].
7.7 Set-Identity
Status: Mandatory
Security: Secure(BEARER)
Urien & All Informational - Expires April 2006 9
EAP-Support in Smartcard October 2005
Once the Identity selection is processed, the supplicant software
needs to set the smartcard EAP framework according to the selected
user's identity. The Set-Identity sets or restarts the smartcard EAP
framework state machine for further processing using the EAP-Packets
method.
7.8 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 the RFC 2284 frames. It retrieves the
appropriate EAP authentication type in the frame and the identifier.
The smartcard maintains the EAP state machine and returns an EAP NAK
packet if the state sequence is broken. In that case it restarts the
AUTHENTICATING state.
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.
7.9 Get-Session-Key (SK)
Status: Mandatory.
Security: Secure(BEARER)
At the end of a successful authentication the supplicant needs to
update the appropriate crypto suite (if any) using the session key.
The Get-Session-Key returns to the supplicant software the key to
initialize radio security protocols like TKIP, or CCMP.
In an 801.1X context, SK should be interpreted as the unicast key.
In an 802.11i or WPA context SK should be interpreted as the PMK
(Pairwise Master Key).

7.10 Get-State.
Status: Optional.
Security: Secure(BEARER)
This command returns the current smartcard state:
1) IDENTITY-NOT-SET, no authentication identity has been selected.
2) AUTHENTICATING.
3) AUTHENTICATED, authentication success, AUTHENTICATING state
restarted.
4) NOT-AUTHENTICATED, AUTHENTICATING state restarted.
7.11 Reset-State.
Status: Optional.
Security: Secure(BEARER)
This command forces the EAP smartcard in the NOT-AUTHENTICATED
state.
7.12 Method Functions
Status: Optional.
Security: Secure(BEARER)
EAP smartcards that are not able to completely process an EAP method
MAY support some essential security procedures, like for example,
-X509 Certificate storage
-Random generator
-Private key encryption
-Private key decryption
-Public key encryption
-Public key decryption
-Symmetric key encryption

EAP-Support in Smartcard October 2005
The supplicant state machine, as described in 802.1x standard is
split between the terminal and the smartcard. The smartcard only
implements the AUTHENTICATING state.
Upon reception of the Set-Identity command smartcard unconditionally
transits in the AUTHENTICATING state.
Upon reception of the EAP Identity-Request message, smartcard
unconditionally moves in the ACQUIRED state, delivers an Identity
response message and re-enters the AUTHENTICATING state.
In agreement with the 802.1X state machine all EAP requests are
processed in the AUTHENTICATING state.
The final EAP notification message (either success or failure)
indicates the end of the authentication process. It’s optionally
forwarded to the EAP smartcard.
If any error occurs during the authentication procedure (reception
of NAK or failure messages ...) the smartcard restarts at the
AUTHENTICATING state where it will wait for an identity request or
the first EAP-Type request.
If the EAP smartcard support security features like PIN code or
biometric identification, all EAP messages will be silently discard
before the occurrence of a successful bearer authentication.
7.14 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) The supplicant software shall indicate in the Set-Identity
command the short identifier to be associated with the selected EAP
identity.
The supplicant 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.

8 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/D7] MAY support a version of PKM ,referred as PKM-EAP,
which at the end of authentication scenario, produces a PMK 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.
8.1 Get-Certificate
Status: Optional.
Security: Secure(BEARER)
This command reads the X509 certificate, associated with an
identification label, which is either implicit or identified by an
index.
8.2 Private-Key-Decryption
Status: Optional.
Security: Secure(BEARER)
This command decrypts a message encrypted with the client public
key, according to [PKCS1]
9 Relationships with the Smartcard Interface.
The Smartcard Interface is a piece of software implemented in the
supplicant that processes the authentication method. This component
must be able to detect a smartcard. If this device is not present,
or if it silently discards an EAP.request message, then Smartcard
Interface MUST reject all incoming request messages by the NAK code.
10 ISO 7816-4 APDUs
This section of the document provides an implementation of the
previous descriptions for an ISO 78176-4 compatible smartcard. 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 hex representation.

The restriction and security related descriptions are not present in
the document. Annexes of this document give implementation examples.
Note: 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.
10.1 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.
- The FETCH command (A0120000xx) is used for reading xx bytes
'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
10.2 Segmentation/Reassembly rules
10.2.1 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.
Urien & All Informational - Expires April 2006 14
EAP-Support in Smartcard October 2005
- 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.
See annexes for examples.
10.2.2 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
(excepted 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 0 and F. The FETCH (INS=12) command (A0120000xx) is used to
read the next bloc.
- See annexes for examples.
10.3 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'.

identity.
10.13 Process-EAP
The command is the method for EAP packet management. The smartcard
identifies the EAP packet type and processes the EAP authentication
according to current state machine. The state machine sequences have
to be respected and the smartcard enforces the EAP sequence
processing.

The EAP request or response packet lengths are represented by the
unknown value XX and YY. The supplicant software should set these
elements in accordance with the EAP packet types.
If "multiple EAP Identity selection" is not supported, P2 (AA value)
shall be set to '00'.
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. These short identifiers
are coded as described in Set-Identity command.
Most EAP request packets will produce an EAP response packet from
the smartcard. If no response is to be produced (e.g. packet
Urien & All Informational - Expires April 2006 19

silently discard because invalid sequence) the smartcard shall
inform the client software with an alert status word ('7000').
Success and failure packets do not require any response from the EAP
client. A "successfully ending of command (90 00)" Status Word shall
be send from the smartcard once 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

12 Security Considerations
Smart cards are a highly effective means of enforcing security
policies. 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).
Urien & All Informational - Expires April 2006 25
EAP-Support in Smartcard October 2005
Applications running on the Smart Card are controlled by the issuer,
and serve to protect the interests of the issuer.
12.1 Security Claims
Security claims expressed in this section are imported from [EAP-SC]
Integrity Protection: no
Replay Protection: no
Confidentiality: yes (section 12.9.2)
Key Derivation: yes (section 12.9.3)
Key Strength: no
Dictionary Attacks: yes (section 12.9.5)
Fast Reconnect: no
Cryptographic Binding: yes (section 12.9.6)
Session Independence: no
Fragmentation: no
Channel Binding: yes (section 12.9.7)
12.2 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.
12.3 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.
The EAP-SC Authentication Method MUST NOT export any secret
cryptographic keys from the smart card.
12.4 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.
12.5 Random Number Generation
Urien & All Informational - Expires April 2006 26
EAP-Support in Smartcard October 2005
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.
12.6 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.
12.7 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.
12.8 Certification
The processes for designing and manufacturing smart cards are
subject to rigorous security controls. This makes possible the
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].
12.9 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.
Urien & All Informational - Expires April 2006 27
EAP-Support in Smartcard October 2005
The following section discusses certain EAP Security Claims and how
they are enhanced by Smart Card security features.
12.9.1 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.
12.9.2 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.
12.9.3 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.
12.9.4 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.
12.9.5 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.
12.9.6 Cryptographic Binding
Smart Cards provides tamper resistant storage for cryptographic keys
and secure execution of the tunnel creation algorithms thus
enhancing the cryptographic binding process.
12.9.7 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.
12.9.8 Protection Against Rogue Networks
Smart Cards facilitate the provisioning and secure storage of
information about trusted parties, such as the root certificates of
Urien & All Informational - Expires April 2006 28
EAP-Support in Smartcard October 2005
trusted networks. This protects the end user against rogue networks
and enables the enforcement of network roaming policies.
12.9.9 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.
12.2 PEAP Consideration
Protected Extensible Authentication Protocol ) [PEAP] is a pre-
processing protocol that allows the privacy of data when processing
EAP protocol. EAP protocol, as defined in [RFC 3748], starts by an
EAP packet request/Identity. The EAP packet response Identity
returns the user's identification label with no privacy being not
part of [RFC 3748].
PEAP protocol allows both part of the EAP packet exchange creating a
session key that can be for privacy over the subsequent execution of
the EAP protocol.
This implementation of EAP in the smartcard MAY allow performing a
PEAP tunnel for privacy. Once PEAP first phase has been successfully
preformed, the EAP protocol (or other protocol) has defined shall be
performed according the EAP smartcard requirements.

16 Annex 3 (Informative) TLS support.
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
16.1 Unix Time issue.
As mentioned in [RFC 2716] TLS RFC the client hello message includes
a 32 byte random number, whose first 4 bytes are interpreted as the
Unix Time. As smartcard is not able to maintain a clock, this
parameter MUST be added to the EAP-TLS Start message by the
Smartcard Interface.

16.2 Fragment Maximum Size.
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.
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. This serves as a fragment ACK.

19.3 EAP-TLS mode1 ISO7816 trace (T=0 protocol)
The EAP-TLS smartcard mode1, 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
In this mode the EAP-TLS smartcard interface doesn't provide RSA
functions. Furthermore all client's parameters (RSA keys and
certificate) are stored in the smartcard.
