Kvaser BlackBird Getting Started Guide

•
The AP must have all of the Kvaser BlackBird’s keys so the AP can decode
transmissions from the Kvaser BlackBird to the AP.
•
The key must occupy the same slot on all nodes (AP and Kvaser
BlackBirds). For example, if the AP defines abc123 as WEP key number 3,
then the Kvaser BlackBirds must define that same string as WEP key 3.

Authentication algorithm
When using WEP encryption, you can choose the Authentication algorithm:
•
Open system means any station may connect to the AP whether that client
station has the correct WEP key or not. This algorithm is also used in WPA
and WPA2 encryption modes.
•
Shared key authentication requires the client station to have the correct WEP
key in order to associate with the access point.
Even though a client station is allowed to associate with an access point, this does
not ensure the client can exchange traffic with that access point. A station must
have the correct WEP key in order to successfully access and decrypt data from an
access point, and to transmit readable data to the access point.
5.4.5
WPA-PSK or WPA2-PSK
Both WPA and WPA2 use Pre-Shared Keys (PSK). WPA-PSK uses the Temporal
Key Integrity Protocol (TKIP). WPA2-PSK uses Counter mode/CBC-MAC Protocol
which uses the Advanced Encryption Algorithm (AES).
5.4.6
Using passphrase to generate keys
Instead of entering the security keys in hexadecimal format, you may use a
Passphrase. Click on the Passphrase button and a Generate keys window will
open, see Figure 14 on Page 19. This window will allow you to enter a pass phrase
and select which types of keys you would like to generate.
For WPA-PSK and WPA2-PSK encryption modes, the key generation is based
upon the network SSID, so make sure that the correct network name is entered in
the SSID field.
