However, it has been largely deprecated due to its numerous vulnerabilities and weaknesses. WEP uses a static key to encrypt data, making it easy for hackers to intercept and decode the transmission. As a result, WEP is no longer considered a secure option for protecting WiFi networks.
WPA: An Improvement Over WEP
WPA, or WiFi Protected Access, was introduced in 2003 as a replacement for WEP. WPA uses a more secure encryption protocol called TKIP, or Temporal Key Integrity Protocol, to protect data transmitted over the network. WPA also introduces a new authentication protocol called PSK, or Pre-Shared Key, which requires a password or passphrase to access the network. While WPA is more secure than WEP, it still has some vulnerabilities and is not considered the most secure option.
WPA2: The Current Standard for WiFi Security
WPA2, or WiFi Protected Access 2, is the current standard for WiFi security. Introduced in 2004, WPA2 uses a more secure encryption protocol called AES, or Advanced Encryption Standard, to protect data transmitted over the network. WPA2 also introduces a new authentication protocol called CCMP, or Counter Mode Cipher Block Chaining Message Authentication Code Protocol, which provides an additional layer of security. WPA2 is considered the most secure option for protecting WiFi networks and is widely used in homes and businesses.
WPA3: The Future of WiFi Security
WPA3, or WiFi Protected Access 3, is the latest WiFi security protocol, introduced in 2018. WPA3 uses a more secure encryption protocol called GCMP, or Galois/Counter Mode Protocol, to protect data transmitted over the network. WPA3 also introduces a new authentication protocol called SAE, or Simultaneous Authentication of Equals, which provides an additional layer of security. WPA3 is designed to provide better protection against cyber threats and is expected to become the new standard for WiFi security in the coming years.
