Explanation:
For a public wireless hot-spot, you want members of the public to be able to access the wireless network
without having to provide them with a password. Therefore, Open System Authentication is the best solution.
Open System Authentication (OSA) is a process by which a computer can gain access to a wireless network
that uses the Wired Equivalent Privacy (WEP) protocol. With OSA, a computer equipped with a wireless
modem can access any WEP network and receive files that are not encrypted.
For OSA to work, the service set identifier (SSID) of the computer should match the SSID of the wireless
access point. The SSID is a sequence of characters that uniquely names a wireless local area network(WLAN). The process occurs in three steps. First, the computer sends a request for authentication to the
access point. Then the access point generates an authentication code, usually at random, intended for use only
during that session. Finally, the computer accepts the authentication code and becomes part of the network as
long as the session continues and the computer remains within range of the original access point.
If it is necessary to exchange encrypted data between a WEP network access point and a wireless-equipped
computer, a stronger authentication process called Shared Key Authentication (SKA) is required.
