4.1.3.2 Wireless network security
Parameter Description
Network
Authentication Type This setting has to be consistent with the wireless networks
that SP908GK intends to connect to.
Open System – No authentication is needed in the wireless
network.
Shared Key – Only wireless devices using a shared key (WEP
Key identified) are allowed to connect to each other.
WPA – WPA provides a scheme of mutual authentication using
either IEEE 802.1x/Extensible Authentication Protocol (EAP)
authentication or pre-shared key (PSK) technology. It provides
a high level of assurance to enterprises, small businesses and
home users that data will remain protected and that only
authorized users may access their networks. For enterprises
that have already deployed IEEE 802.1x authentication, WPA
offers the advantage of leveraging the existing authentication
databases and infrastructure.
WPA-PSK – It is a special mode designed for home and small
business users who do not have access to network
authentication servers. In this mode, known as Pre-Shared
Key, the user manually enters the starting password in their
access point or gateway, as well as in each wireless station in
the network. WPA-PSK takes over automatically from that
point, keeping unauthorized users that don't have the matching
password from joining the network, while encrypting the data
traveling between authorized devices.
WPA2 – Like WPA, WPA2 supports IEEE 802.1 x/EAP
authentication or PSK technology. It also includes a new

- 14 -
advanced encryption mechanism using the Advanced
Encryption Standard (AES). AES is required by the corporate
user or government users. The difference between WPA and
WPA2 is that WPA2 provides data encryption via the AES. In
contrast, WPA uses Temporal Key Integrity Protocol (TKIP).
WPA2-PSK – WPA2-PSK is also for home and small business.
The difference between WPA-PSK and WPA2-PSK is that
WPA2-PSK provides data encryption via the AES. In contrast,
WPA-PSK uses Temporal Key Integrity Protocol (TKIP).
WPA 802.1X – Set the wireless devices using a WPA 802.1X
mode
WPA2 802.1X – Set the wireless devices using a WPA2
802.1X mode
Data encryption None – Disable the encryption mode.
WEP – Enable the WEP Data Encryption. When the item is
selected, you have to continue setting the WEP Encryption
keys.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the
temporal key every 10,000 packets (a packet is a kind of
message transmitted over a network.) This ensures much
greater security than the standard WEP security.
AES – AES has been developed to ensure the highest degree
of security and authenticity for digital information and is the
most advanced solution defined by IEEE 802.11i for security in
the wireless network.
Note: All devices in the network should use the same
encryption method to ensure the communication.
802.1x Setting When you set the Authentication Type to Open, Shared, WPA
or WPA2, you can also enable IEEE 802.1x setting to use the
authentication server or certification server to authenticate
client users.
WPA Pre-Shared Key The WPA-PSK key can be from 8 to 64 characters and can be
letters or numbers. This same key must be used on all of the
wireless stations in the network.
WEP Key
(Key1 ~ Key4) The WEP keys are used to encrypt data transmitted in the
wireless network. There are two types of key length: 64-bit and
128-bit. Select the default encryption key from Key 1 to Key 4
by selected the radio button.
Fill the text box by as instructed below:
64-bit – Input 10-digit Hex values (in the “A-F”, “a-f” and “0-9”
range) or 5-digit ASCII characters (including “a-z” and “0-9”) as
the encryption keys. For example: “0123456aef“or “test1”.
128-bit – Input 26-digit Hex values (in the “A-F”, “a-f” and “0-9”
range) or 13-digit ASCII characters (including “a-z” and “0-9”)
as the encryption keys. For example:
“01234567890123456789abcdef“ or “administrator”.

The IEEE 802.1X specification describes a protocol used for authenticating both clients
and servers on a network. The authentication algorithms and methods are those provided
by the Extensible Authentication Protocol (EAP), a method of authentication that has
been in use for a number of years on networks that provide Point-to-Point Protocol
(PPP) support as many internet service providers and enterprises do.
When an AP acting as an authenticator detects a wireless station on the LAN, it sends an
EAP-Request for the user's identity to the device. (EAP, the Extensible Authentication
Protocol, is an authentication protocol that runs before network layer protocols transmit
data over the link.) In turn, the device responds with its identity, and the AP relays this
identity to an authentication server, which is typically an external RADIUS server.

- 16 -
Parameter Description
Authentication Type The EAP authentication protocols this card supports are
listed below. This setting has to be consistent with the
wireless APs or Routers that SP908GK intends to connect.
PEAP &TTLS – PEAP and TTLS are similar and easier than
TLS in that they specify a stand-alone authentication
protocol to be used within an encrypted tunnel. TTLS
supports any protocol within its tunnel, including CHAP,
MS-CHAP, MS-CHAPv2, PAP and EAP-MD5. PEAP
specifies that an EAP-compliant authentication protocol must
be used; this card supports EAP-MSCHAP v2,
EAP-TLS/Smart card and Generic Token Card. The client
certificate is optional for authentication needs.
TLS/Smart Card –TLS is the most secure of the EAP
protocols but is not easy to use. It requires exchanging
digital certificates in the authentication phase. The server
presents a certificate to the client.After validating the
server’s certificate, the client will then present a client
certificate to the server for validation.
MD5-Challenge – MD5-Challenge is the easiest EAP Type.
It requires the wireless station to enter a set of user name
and password as the identity to RADIUS Server.
Session Resumption Select from “Disabled”, “Reauthentication”, “Roaming”,
“SameSSID” and “Always” options when you want to
recover the session in different status.
Identity Name the server for server identification.
Password Enter the password for server identification.
Use Client Certificate A client certificate is required for TLS, and is optional for
TTLS and PEAP. This item forces a client certificate to be
selected from the appropriate Windows Certificate Store and
made available to the RADIUS server for certification.
Tunneled Authentication
Protocol When the authentication type is PEAP or TTLS, select a
protocol for building the encrypted tunnel.
Identity This is the protected user EAP Identity used for
authentication. The identity specified may contain up to 63
ASCII characters, which is case sensitive and takes the form
of a Network Access Identifier, consisting of <name of the
user>@<user’s home realm>. The user’s home realm is
optional and indicates the routing domain.
Password The password used for authentication. It may contain up to
63 ASCII characters and is case sensitive.

- 17 -
4.1.3.4 802.1x Setting-CA Server
Parameter Description
Use Certificate Chain When the EAP authentication type such as TLS, TTLS or
PEAP is selected and requires a certification to tell the client
what server credentials to accept from the authentication
server in order to verify the server, you have to enable this
function.
Certificate Issuer Choose the server from the list to issue the certificate. If “Any
Trusted CA” is selected, any CA included on the list (provided
by the Microsoft Certificate Store) will be permitted.
Allow Intermediate
Certificates When the server designates an issuer as a trusted root authority, it places the issuer's self-signed certificate, which
contains the issuer's public key, into the trusted root
certification authority certificate store of the host computer.
Intermediate or subordinate certification authorities are trusted
only if they have a valid certification path from a trusted root
certification authority.
Server Name Enter the authentication server name.
Server name must match
exactly When selected, the server name must match exactly with the server name found on the certificate.
Domain name must end in
specified name When selected, the server name field will identify a domain. The certificate must use a server name belonging to this
domain or to one of its sub-domains (e.g. zeelans.com, where
the server is blueberry.zeelans.com) but it may be any name
used in the certificate name field.
