Wireless Network Install Guide_ 

WPA(WPA2)-Enterprise is an authentication method to use IEEE802.1x standard based on 

an additional EAP(Extensible Authentication Protocol). WPA(WAP2)-Enterprise authorizes 

and identifies users based on an authentication server called RADIUS(Remote 

Authentication Dial In User Server).

•

WPA(WPA2)-Enterprise configuration is supported through a network cable. You 

can set up a wireless printer security using the SyncThru™ Web Service program.

•

Supporting specifications about WPA-Enterprise can differ according to the 

models.

•

 

EAP-TLS (EAP using Transport Layer Security) : EAP-Transport Layer Security or 

EAP-TLS, defined in RFC 5216, is an IETF open standard, and is well-supported among 

wireless vendors. It uses PKI(Public Key Infrastructure) to secure authentication 

between an authentication server and client. EAP-TLS uses X.509-compliant digital 

certificates for both client and network sever authentication. So you have to install root 

certificate and client certificate on the Samsung Network Printer.

•

 

EAP-TTLS (EAP using Tunneled Transport Layer Security) : EAP-TTLS is an EAP 

protocol that extends TLS. EAP-TLS is widely supported, however no native OS 

supports EAP-TTLS in Microsoft Windows. EAP-TTLS uses X.509-compliant digital 

certificate for network server authentication. This also requires 802.1x user name, user 

password and TTLS identity used by inner authentication protocol for client 

authentication over a secure connection. 

•

 

PEAP (Protected Extensible Authentication Protocol) : PEAP is similar in design to 

EAP-TTLS. PEAP is widely supported and provides very good security. Samsung 

Network Printer supports PEAPv0/EAP-MSCHAPv2. PEAP also uses X.509-compliant 

digital certificate for network server authentication and requires 802.1x user name, user 

password used by inner authentication protocol for client authentication over a secure 

connection.

Certificates are used to validate the identity of clients and network servers and allow 

encrypted data communications for EAP/802.1x authentication. Certificates may be issued 

and signed by a trusted third party, called Certificate Authority, or CA.
In EAP/802.1x authentications such as EAP-TLS, EAP-TTLS, and PEAP, Samsung print 

server may require to configure one or both of the following certificates:

•

Root Certificate : A certificate from a trusted Certificate Authority (CA) is used to 

validate the identity of a network authentication server while EAP authentication 

methods such as EAP-TLS, EAP-TTLS, PEAP, are performed. The network 

authentication server's identity will be validated when information of root certificate 

installed on Samsung print server is identical to the information on a certificate received 

from the network authentication server, such as RADIUS server. Root certificate that can 

be installed on Samsung Network Printer must be the form of Base64 Encoded X.509 

with .cer extension and be less than 3072 bytes.

•

Client Certificate : Client Certificate is used to the identity validation of Samsung 

Network Printer from the network authentication server, such as RADIUS server, while 

EAP-TLS authentication method is performed. Client certificate that can be installed on 

Samsung Network Printer must be the form of PKCS #12 / Personal Information 

Exchange with .pfx extension and be less than 3072 bytes.
