WEP was one of the early security protocols for Wi-Fi networks.
It uses a shared key mechanism for authentication and RC4 for encryption.
WEP, however, has severe vulnerabilities and is considered insecure. It can be easily cracked using various tools.
Wi-Fi Protected Access (WPA):
WPA was introduced as an improvement over WEP to address its vulnerabilities.
Temporal Key Integrity Protocol (TKIP) was introduced to provide stronger encryption than WEP.
WPA also introduced a more robust key management system.
WPA2 (Wi-Fi Protected Access 2):
WPA2 is an enhancement over WPA, providing stronger security.
It uses the Advanced Encryption Standard (AES) for encryption, which is considered more secure than TKIP.
WPA3 (Wi-Fi Protected Access 3):
WPA3 is the latest standard, addressing vulnerabilities in WPA2.
It introduces stronger encryption protocols, such as Simultaneous Authentication of Equals (SAE) for key establishment, providing enhanced protection against various attacks.
802.11i:
802.11i is a standard that defines security mechanisms for wireless networks.
