Data encryption
For Open and Shared authentication mode, the configuration options of
encryption type are Disabled and WEP. For WPA, WPA-PSK, WPA2 and
WPA2-PSK authentication mode, Temporal Key Integrity Protocol (TKIP)
encryption and Advanced Encryption Standard (AES) encryption are supported.
Disabled - Disable the encryption function.
WEP - WEP Key is used to encrypt your data before it is transmitted over air.
You can only connect and communicate with wireless devices that use the
same WEP keys.
TKIP - TKIP uses an encryption algorithm method that is more stringent than
the WEP algorithm. It also uses existing WLAN calculation facilities to perform
encryption. TKIP verifies the security configuration after the encryption keys are
determined.
AES: AES is a symmetric 128-bit block encryption technique that works
simultaneously on multiple network layers.
Wireless Network Key
This option is enabled only if you select WPA-PSK or WPA2-PSK authentication
mode. Select “TKIP” or “AES” in the encryption filed as encryption mode to
begin the encryption proceed. Note: 8 to 64 characters are required in this field.
Wireless Network Key (WEP)
This option is configurable only if you enable WEP in Network Authentication
field. The WEP Key is a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal
digits which is used to encrypt and decrypt data packets.
Key Format
You can select to enter Hexadecimal digits (0~9, a~f, and A~F) or ASCII
characters to setup keys by defining the Key Format.
Key Length
For 64 bits encryption, each key contains 10 hex digits or 5 ASCII characters.
For 128 bits encryption, each key contains 26 hex digits or 13 ASCII characters.
Manual assign WEP keys - When you select this option, the cursor appears
in the field for Key 1. For 64-bit encryption, you are required to enter four WEP
Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and A~F). For 128-bit
encryption, you are required to enter four WEP Keys. Each Key contains
exactly 26 hex digits (0~9, a~f, and A~F).
