What is WPA and how does it work?
WPA, or Wi-Fi Protected Access, is a security protocol designed to protect Wi-Fi networks from unauthorized access. It was introduced in 2003 as a replacement for the outdated WEP (Wired Equivalent Privacy) protocol. WPA uses a combination of encryption and authentication to secure data transmission over Wi-Fi networks. The protocol relies on a pre-shared key (PSK) or a Remote Authentication Dial-In User Service (RADIUS) server to authenticate devices before granting access to the network.
The WPA protocol uses the Temporal Key Integrity Protocol (TKIP) to encrypt data transmission. TKIP generates a unique key for each packet of data, making it more secure than WEP. However, WPA has some limitations, including a relatively weak encryption algorithm and vulnerability to certain types of attacks, such as brute-force attacks. As a result, WPA has been largely replaced by more secure protocols like WPA2 and WPA3. Despite its limitations, WPA remains a widely supported protocol and is still used in many legacy devices.
