Both WPA and WPA2 offer a high level of assurance for end users and network administrators that their data will remain private and that access to their networks will be restricted to authorized users. Both have personal and enterprise modes of operation that meet the distinct needs of the two market segments. The Enterprise Mode of each uses IEEE 802.1X and extensible authentication protocol (EAP) for authentication. WPA2 provides a stronger encryption mechanism through AES, which is a requirement for some corporate and government users. TKIP, the encryption mechanism in WPA, relies on RC4 instead of Triple Data Encryption Standard (3DES), AES, or another encryption algorithm
