Levels of authentication available with the OkiLAN 510w (wireless NIC)
The screenshot below is taken from the web configuration page of the OkiLAN 510w.
It shows the 4 levels of authentication that can be set for wireless communication. They are in order of security with OPEN being the least secure and EAP being the most secure.
Selecting this means that the communication link will have no authentication and no encryption and should only be used where the required security level is very low,
This setting uses WEP (Wired Equivalent Privacy) for ENCRYPTION. The encryption level can be set to 64bit or 128bit. This uses a shared key for AUTHENTICATION. The shared key can only be changed manually and there are hacker utilities available on the internet that can be used to 'break' the key.
Uses TKIP (Temporal Key Integrity Protocol) for ENCRYPTION. TKIP is an enhancement of WEP and uses a 128bit key that is continually changing to overcome the inherent problems with WEP. Authentication is carried out using a pre-shared key.
Similar to WPA-PSK in that it also uses TKIP for ENCRYPTION. However AUTHENTICATION is carried out using a Radius or authentication server using certificates issued from a Certification Authority (CA) such as Entrust or Versign.
