Detailed explanation-1: -The WPA Wi-Fi protocol is more secure than WEP, because it uses a 256-bit key for encryption, which is a major upgrade from the 64-bit and 128-bit keys used by the WEP system. WPA also uses the Temporal Key Integrity Protocol (TKIP), which dynamically generates a new key for each packet, or unit of data.
Detailed explanation-2: -Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b. That standard is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.
Detailed explanation-3: -What is WPA? Next came WPA, or Wi-Fi Protected Access. Introduced in 2003, this protocol was the Wi-Fi Alliance’s replacement for WEP.
