Question:

The Wired Equivalent Privacy (WEP) standard was created in order to give wireless networks safety and security features similar to that of wired networks.

(a) List three problems caused by the absence of a key establishment protocol in WEP.

(b) The two forms of authentication provided by 802.11 are Open System Authentication (OSA) and Shared Key Authentication (SKA).

i. Differentiate between these two forms of authentication.
ii. The authentication mechanisms in 802.11 suffer from many drawbacks. Give three drawbacks of using SKA.
