ZyXEL G-1000 v2 User’s Guide 178 WP A(2) W i-Fi Protected Access (WP A) is a subset of the IEEE 802.1 1i standard. WP A2 (IEEE 802.1 1i) is a wireless security standard that defines stronger encryp tion, authentication and key manage ment than WP A. Key differences between WP A(2) and WEP are improved data encryption and user authentication. If b[...]

ZyXEL G-1000 v2 User’s Guide 179 By generating unique data encryption keys for ev ery data packet and by creating an integrity checking mechanism (MIC), with TKIP and AES it is more difficult to decrypt data on a W i-Fi network than WEP and dif ficult for an intruder to break into the network. The encryption mechanisms used for WP A(2) and WP A(2[...]
