Which encryption does WPA1 use for data protection?

WPA1 (Wi-Fi Protected Access) primarily uses TKIP (Temporal Key Integrity Protocol) for data encryption. TKIP was designed as an interim solution to address the security vulnerabilities of WEP without requiring a hardware upgrade. It provides per-packet key mixing, a message integrity check, and a re-keying mechanism, making it significantly more secure than WEP. PEAP (Protected Extensible Authentication Protocol) and EAP (Extensible Authentication Protocol) are authentication protocols, not encryption protocols for data protection. While they are used in secure wireless networks, they handle user authentication, not the encryption of the data itself. AES (Advanced Encryption Standard) is a stronger encryption standard used by WPA2 and WPA3, offering more robust security than TKIP.
