  • Page 24: Ad-Hoc (Ibss)

    ZyAIR G-220 User’s Guide To connect to a wired network within a coverage area using Access Points (APs), set the ZyAIR operation mode to Infrastructure (BSS). An AP acts as a bridge between the wireless stations and the wired network. In case you do not wish to connect to a wired network, but prefer to set up a small independent wireless workgroup without an AP, use the Ad-hoc (IBSS) (Independent Basic Service Set) mode.

    ZyAIR G-220 User’s Guide 2.2.2 IEEE 802.1x The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server. 2.2.2.1 EAP Authentication EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication.

  • Page 28: Wpa-Psk Application Example

    ZyAIR G-220 User’s Guide TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the 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.

    ZyAIR G-220 User’s Guide Figure 8 WPA-PSK Authentication 2.2.5 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.

  • Page 30: Authentication Type

    ZyAIR G-220 User’s Guide 2.3 Authentication Type The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP. Three authentication modes are defined: Auto, Open System and Shared Key. • Open System mode is implemented for ease-of-use and when security is not an issue.
