Choose the security method according to the Access Point security policy. Subscriber
station should be authorized by Access Point in order to get access to the network and
all the user data transferred between subscriber station and Access Point will be
encrypted if the wireless security methods are used.
Security: AirOS supports all the popular 802.11 security options such as WEP, WPA,
and WPA2. Select the security mode of your wireless network:
WEP – enable WEP encryption. WEP (Wired Equivalent Privacy) is based on the
IEEE 802.11 standard and uses the RC4 encryption algorithm. Enabling WEP
allows you to increase security by encrypting data being transferred over your
wireless network. WEP is the oldest security algorithm.
WPA – enable WPA™ security mode. Wi-Fi Protected Access - WPA™ (IEEE
802.11i/D3.0) and WPA2™ (IEEE 802.11i) with pre-shared key management
protocol offers improved security methods as they are new protocols that were
created under the 802.11i standard to address weaknesses in the WEP
approach.
WPA
™ and
WPA2
™ support the following ciphers for data encryption:
TKIP
- Temporal Key Integrity Protocol which uses RC4 encryption algorithm.
CCMP
- Counter Mode with Cipher Block Chaining Message Authentication Code
Protocol which uses the Advanced Encryption Standard (AES) algorithm.
The device will use the strongest cipher (CCMP) in Station and Access Point wireless
mode by default. If CCMP is not supported on the other side of the link the TKIP
encryption will be used - like in situation when the device acts as Access Point with
WPA security enabled and at least one wireless station (without CCMP support) is
connected to it.
WPA-TKIP
– enable WPA™ security mode with TKIP support only.
WPA-AES
– enable WPA™ security mode with AES support only.
WPA2
– enable WPA2™ security mode.
WPA2-TKIP
– enable WPA2™ security mode with TKIP support only.
WPA2-AES
– enable WPA2™ security mode with AES support only.
Authentication Type: field relates only to the WEP security option. One of the
following authentication modes should be selected if WEP security method is used:
Open Authentication
– station is authenticated automatically by AP (selected by
default).
Shared Authentication
– station is authenticated after the challenge, generated
by AP.
WEP Key Length: 64-bit (selected by default) or 128-bit WEP Key length should be
selected if WEP security method is used. The
128-bit
option will provide more security.
Key Type:
HEX
(selected by default) or
ASCII
option specifies the character format for
the WEP key if WEP security method is used.
WEP Key: WEP encryption key for the wireless traffic encryption and decryption
should be specified if WEP security method is used:
