Encryption
Encryption protects the transferred data from eavesdropping and corruption
can only disable encryption in the Encryption check box if you have selected Open
System for authentication in the Basic WLAN menu. All other security methods
include both authentication and encryption. Various schemes are used for
encryption:
● WEP (Wired Equivalent Privacy)
A weak, symmetrical stre
keys based on the RC4 a
● TKIP (Temporal Key Integrity Protocol)
A symmetrical stream encryption method with the RC4 algorithm (Ron's Code
4). In contrast to the weak WEP encryption, TKIP uses changing keys derived
from a main key. TKIP can also r
● AES (Advanced Encryption Standard)
Strong symmetrical block encryption method based on the Rijndael algorithm
that further improves the functions of TKIP.
Encryption key source
The encryption key source indicates whether the key is configured locally and fixed
(local) or whether it is negotiated by a higher protocol and an authentication server
(server).
Security Level for WLAN list box
Select a security level that is supported by all clients. The content of the next page
