Describe the main characteristics of the open system authentication method.
What will be an ideal response?
There are two types of authentication supported by the 802.11 standard. Open system authentication is the default method. A device discovers a wireless network in the vicinity through scanning the radio frequency and sends a frame known as an association request frame to the AP. The frame carries information about the data rates that the device can support along with the Service Set Identifier (SSID) of the network it wants to join. The SSID serves as the "network name" for the wireless network and can be any alphanumeric string from 2 to 32 characters. After receiving the association request frame, the access point compares the SSID received with the actual SSID of the network. If the two match then the wireless device is authenticated.
