Silex technology SX-200 user manual Key Selection

User’s Guide

•WPA uses TKIP encryption.

•WPA2 uses CCMP encryption.

•WPA2-WPA uses CCMP for pair-wise encryption, but allows TKIP for group encryption.

Key Selection

If WEP encryption is selected, and the authentication mode is not an EAP (802.1x) mode, select the desired WEP key to be used, one through four.

WEP Key

These fields are ignored unless the encryption mode is 64 or 128 bit WEP. Enter up to 10 hexadecimal digits for 64 bit WEP, or 26 hexadecimal digits for 128 bit WEP.

Authentication Type

Choose type of authentication to be performed with the network access point, or with a peer unit in Ad- hoc mode.

User ID

Enter the logon user ID that the server uses to authenticate to the 802.1x-enabled network. The user ID and password must be in the authentication server database, and is used in TTLS, LEAP, and PEAP configurations. The default user ID is 'anonymous'. A realm defines a grouping of users. If a realm is required for your network, it is separated from the user ID by a '@' character. Realms make it easier to segregate user groups into independently administered databases, to apply policies on a user group basis, and to establish roaming agreements to name a few applications. The default realm if not specified is 'anonymous'. Realm is used with TTLS configurations, and sometimes with PEAP.

Password

Enter the logon password that the server uses to authenticate to the 802.1x enabled network. The user ID and password must be in the authentication server database, and is used in TTLS, LEAP, and PEAP configurations. The password may be a text string, or a string of hex bytes prefixed with '\x'. The default password is 'anonymous'.

Certificate Common Name

Enter the name of the certificate on the primary authentication server. If both of the

common names are set to null, all certificates are accepted. The default is null. Certificate common name is used in TTLS and PEAP configurations.

Certificate Root Key

Enter the authentication key used to verify the root certificate in the certificate chain provided by the authentication server. To set to null, leave this field blank. Certificate Root Key is used in TTLS and PEAP configurations. The Certificate Root Key can be extracted by clicking Browse and selecting the actual certificate if you don’t want to type it in manually.

Certificate Root Key Exponent

This value must match the authentication server certificate value. The default is 65537 (x10001). Certificate Root Key Exponent is used in TTLS and PEAP configurations. The Certificate Root Key Exponent can be extracted by clicking Browse and selecting the actual certificate if you don’t want to type it in manually.

Authentication Protocol

This field determines how the server authenticates itself to the 802.1x enabled network after an 802.1x session is established. The default is PAP. Sometimes referred to as inner-authentication protocol, it is used in TTLS and PEAP configurations.

Pre-Shared Key

If the PSK mode of authentication is selected with WPA (TKIP) or WPA2 (CCMP) encryption, the key value or pass-phrase entered here is used to initialize the session with the access point. If a key value is entered, it must be exactly 64 hex characters. A pass-phrase must be 8 to 63 displayable characters.
