ADSL Router User Manual
Authentication Type:
The ADSL Router supports two authentication types: Open System and Shared key. This should be considered with the WEP (Wired Equivalent Privacy) mechanism.
Format:
Choose the form of encryption key. You have to select either Hexadecimal digits or ASCII characters and type the keys on the fields of Key 1 to Key 4.
Key 1 to 4:
Fill out the WEP keys according to the key length. For
Default Transmission Key: Select one of the network keys that you set on the Key boxes as the default one.
Click Apply for activation when the settings are done.
Open System means that it allows any client to authenticate and attempt to communicate with a bridge. The client can only communicate if its WEP keys match the router’s WEP keys.
Shared Key means that a bridge or router will send an unencrypted text string to any client attempting to communicate with the router. The client requesting authentication encrypts the text and sends back to the router. Both unencrypted and encrypted can be monitored, yet it leaves the bridge open to be attacked by any intruder if he calculates the WEP key by comparing the text strings. That is why shared key authentication can be less secure than open authentication.
