Security - D-Link DSL-2640B User Manual

Section 5 - Home
The next screen is the Wireless – Security screen which allows you to select the network authentication method and
to enable or disable WEP encryption. Note that depending on the network authentication selected, the screen will
change to reflect the authentication method and additional fields will appear which may require configuration.
Network authentication methods include the following:
Open:
Anyone can access the network. The default is a disabled WEP encryption setting.
WEP encryption is enabled and encryption key strength of 64-
Shared:
bit or 18-bit needs to be selected. Click on Set Encryption Keys
to manually set the network encryption keys. Up to 4 different
keys can be set and you can come back to select which one
to use at anytime.
802.1x:
Requires mutual authentication between a client station and
the router by including a RADIUS-based authentication server.
Information about the RADIUS server such as its IP address,
port and key must be entered. WEP encryption is also enabled
and the encryption strength must also be selected.
WPA:
(Wi-Fi Protected Access)– usually used for the larger Enterprise
environment, it uses a RADIUS server and TKIP (Temporal
Key Integrity Protocol) encryption (instead of WEP encryption
which is disabled). TKIP uses18-bit dynamic session keys
(per user, per session, and per packet keys).
WPA-PSK: (Wi-Fi Protected Access – Pre-Shared Key)—WPA for home and SOHO environments also using the same strong TKIP
encryption, per-packet key construction, and key management that WPA provides in the enterprise environment. The main
difference is that the password is entered manually. A group re-key interval time is also required.
WPA2:
(Wi-Fi Protected Access )—second generation of WPA which uses AES (Advanced Encryption Standard) instead of TKIP
as its encryption method. Network re-auth interval is the time in which another key needs to be dynamically issued.
WPA2-PSK: (Wi-Fi Protected Access  – Pre-Shared Key)—suitable for home and SOHO environments, it also uses AES encryption
and requires you to enter a password and an re-key interval time.
