ioLogik 2500 Series Wireless LAN Network Setup and Configuration (for wireless LAN models)
7-4
When WEP is enabled as a security mode, the length of a key (the so-called WEP seed) can be specified as
64/128 bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The ioLogik 2500-
WL1 provides 4 entities of WEP key settings that can be selected to use with Key index. The selected key
setting specifies the key to be used as a send-key for encrypting traffic from the AP side to the wireless
client side. All 4 WEP keys are used as receive-keys to decrypt traffic from the wireless client side to the AP
side.
The WEP key can be presented in two Key types, HEX and ASCII. Each ASCII character has 8 bits, so a 64-
bit WEP key contains 5 characters, and a 128-bit key has 13 characters. In hex, each character uses 4 bits,
so a 64-bit key has 10 hex characters, and a 128-bit key has 26 characters.

WPA/WPA2-Personal
Also known as WPA/WPA2-PSK. You will need to specify the Pre-Shared Key in the Passphrase field, which
will be used by the TKIP or AES engine as a master key to generate keys that actually encrypt outgoing
packets and decrypt incoming packets.
WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption
method. WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified
version of 802.11i. The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long
as WEP. The key is regularly changed so that true session is secured.
Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA
security mode of some wireless APs and clients as well. The ioLogik 2500-WL1 also supports AES algorithms
in WPA and WPA2 for better compatibility.
