P-661H/HW Series User’s Guide 364 Appendix K WP A and WP A2 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 tha t defines stronger encryp tion, authentication and key manage ment than WP A. Key differences between WP A or WP A2 and W EP are improved data encryption an[...]

P-661H/HW Series User’s Guide Appendix K 365 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[...]
