4. What is the difference between Open System and Shared Key of Authentication Type? What is the difference between Open System and Shared Key of Authentication Type?

Open System:
The default authentication service that simply announces the desire to associate with another station or access point. A station can authenticate with any other station or access point using open system authentication if the receiving station designates open system authentication.

Share Key:
The optional authentication that involves a more rigorous exchange of frames, ensuring that the requesting station is authenticated. For a station to use shared key authentication, it must implement WEP
, WPA or WPA2.
