Page 286: Dynamic Wep Key Exchange
RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. NBG4115 User’s Guide...
Page 287 The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption NBG4115 User’s Guide...
Page 288 The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly. A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and the client. NBG4115 User’s Guide...
Page 289 The AP checks each wireless client's password and allows it to join the network only if the password matches. The AP and wireless clients generate a common PMK (Pairwise Master Key).
