WEP 128-bit

WPA with TKIP

WPA2 with AES

Detailed explanation-1: -It uses a single key to protect the network and aims to provide security to wireless networks. After a time, WEP found that the 40-bit encryption key used in WEP was vulnerable and unsafe. Among all other Wi-Fi security protocols, WEP is considered the least secure.
Detailed explanation-2: -WEP stands for Wired Equivalent Privacy, and WPA stands for Wireless Protected Access. WPA2 is the second version of the WPA standard. Using some encryption is always better than using none, but WEP is the least secure of these standards, and you should not use it if you can avoid it.
Detailed explanation-3: -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-4: -WEP encrypts traffic using a 64-or 128-bit key in hexadecimal. This is a static key, which means all traffic, regardless of device, is encrypted using a single key. A WEP key allows computers on a network to exchange encoded messages while hiding the messages’ contents from intruders.
