ZyAIR G-110 User’s Guide 2.8.2 Authentication Mode The IEEE 802.11b standard describes a simple authentication method between the wireless stations and AP. Two authentication modes are defined: Open and Shared. Open authentication mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP do not share a secret key. Thus the wireless stations can associate with any AP and listen to any data transmitted plaintext.
ZyAIR G-110 User’s Guide Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and distributed by the authentication server. It includes a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice.
ZyAIR G-110 User’s Guide Figure 2-11 WPA - PSK Authentication 2.8.6 WPA 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 application example with an external RADIUS server looks as follows. “A” is the RADIUS server. “DS” is the distribution system. Step 1. The AP passes the wireless client’s authentication request to the RADIUS server. Step 2.
