Description: WPA (Wi-Fi Protected Access) is a security protocol designed to protect wireless networks. Introduced in 2003 by the Wi-Fi Alliance, WPA was created in response to the vulnerabilities of the previously used WEP (Wired Equivalent Privacy) protocol. WPA implements a more robust encryption system and uses the TKIP (Temporal Key Integrity Protocol) to enhance the security of Wi-Fi connections. Additionally, WPA allows for user authentication through a RADIUS server, providing an extra layer of protection. Over time, WPA has evolved, leading to the development of more advanced versions such as WPA2 and WPA3, which offer significant improvements in security and key management. These versions utilize the AES (Advanced Encryption Standard) protocol for data encryption, ensuring greater resistance against malicious attacks. Implementing WPA is crucial for protecting information transmitted over wireless networks, especially in environments where data security is a priority.
History: WPA was introduced in 2003 as a temporary solution to address the deficiencies of WEP. In 2004, WPA2 was released, incorporating the AES encryption standard, providing even greater security. WPA3 was announced in 2018, enhancing security in public networks and offering protection against dictionary attacks.
Uses: WPA is used in home and business Wi-Fi networks to protect information transmitted between devices. It is essential in environments where data security is critical, such as in offices, universities, and public places.
Examples: An example of WPA usage is in a workplace Wi-Fi network that requires user authentication and data encryption to protect sensitive information.
