Figure 174 WPA(2)-PSK Authentication
WPA(2) with RADIUS Application Example
You need the IP address of the RADIUS server, its port number (default is 1812),
and the RADIUS shared secret. A WPA(2) application example with an external
RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution
system.
The AP passes the wireless client's authentication request to the
1
RADIUS server.
The RADIUS server then checks the user's identification against its
2
database and grants or denies network access accordingly.
The RADIUS server distributes a Pairwise Master Key (PMK) key to the
3
AP that then sets up a key hierarchy and management system, using
the pair-wise key to dynamically generate unique data encryption keys
to encrypt every data packet that is wirelessly communicated between
the AP and the wireless clients.
Security Parameters Summary
Refer to this table to see what other security parameters you should configure for
each Authentication Method/ key management protocol type. MAC address filters
are not dependent on how you configure these security features.
