Evolution of Wireless Security Protocols
- Different wireless security methods and protocols are used in wireless networks, with most networks requiring a password for secure access.
- WEP (Wired Equivalent Privacy) was an early security protocol for wireless networks but is now outdated due to vulnerabilities in its 40-bit encryption key.
- WPA (Wi-Fi Protected Access) was developed to address WEP's issues, using a stronger encryption method called TKIP for data integrity.
- WPA2 provides even stronger security than WPA by using AES (Advanced Encryption Standard), resistant to brute-force attacks and adopted by the U.S. federal government.
- WPA3, introduced in 2018, offers cutting-edge security features, simplifying Wi-Fi security and enhancing protection against password guessing attempts.
