Which WLAN security standard supports AES encryption?

WPA2 is the WLAN security standard that supports AES (Advanced Encryption Standard) encryption, which is a significant improvement over earlier security protocols. AES is a robust encryption algorithm that provides a high level of security for wireless networks. WPA2 is designed to protect personal and enterprise wireless networks and utilizes AES to ensure data confidentiality and integrity during transmission.

The adoption of AES in WPA2 allows for stronger encryption compared to previous standards, making it less susceptible to various types of attacks such as key cracking and eavesdropping. This enhancement is crucial for securing sensitive information exchanged over wireless networks.

In contrast, WEP (Wired Equivalent Privacy) uses RC4 encryption, which is outdated and vulnerable to attacks. WPA (Wi-Fi Protected Access), while an improvement over WEP, initially supported TKIP (Temporal Key Integrity Protocol) rather than AES. 802.1X is not a security standard in itself but a network access control protocol that provides an authentication framework to control access to the network; it can work in conjunction with security protocols like WPA and WPA2 but does not define its own encryption methods.
