Which protocol replaces RC4 with AES for greater security?

WPA2 is the protocol that replaces the RC4 encryption algorithm with AES (Advanced Encryption Standard) to provide a higher level of security for wireless networks. RC4 has known vulnerabilities that can be exploited, making it less secure for encrypting data. By using AES, WPA2 significantly enhances the confidentiality and integrity of the data transmitted over wireless networks.

AES is a symmetric key encryption algorithm that has been widely adopted due to its strength and efficiency. It supports longer key lengths and is less susceptible to certain types of attacks compared to RC4. As organizations increasingly prioritize security, WPA2's use of AES offers a robust solution for safeguarding sensitive information in wireless communications.

WPA, while an improvement over the original WEP protocol, still relies on RC4 for encryption, which does not provide the same level of security as AES. LEAP and PEAP are authentication protocols designed for use with wireless networks, but they are not specifically focused on replacing RC4 with AES for encryption; instead, they address different aspects of network security.
