Final answer:
WEP, WPA, and PSK are examples of security protocols used to encrypt data and protect wireless network traffic, with WPA2 providing stronger encryption through the CCMP method based on AES.
Step-by-step explanation:
Technologies such as WEP, WPA, and PSK are examples of protocols that can be used on wireless networks. Wireless network security is crucial for protecting data, and these protocols help secure network traffic by encrypting the data that is transmitted over wireless networks.
WEP, or Wired Equivalent Privacy, was one of the earliest security protocols but is now considered outdated and insecure. WPA (Wi-Fi Protected Access) improved upon WEP by providing stronger security features. WPA2, which is a more secure version of WPA, employs a stronger encryption method called CCMP (Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) based on the AES standard. Lastly, PSK, or Pre-Shared Key, is a method of authentication used in WPA and WPA2 where every user enters the same key to connect to the Wi-Fi network.
