In April 2010, the Wi-Fi Alliance announced the inclusion of additional EAP [30] types to its WPA- and WPA2-Enterprise certification programs. [31] This was to ensure that WPA-Enterprise certified products can interoperate with one another. As of 2010 the certification program includes the following EAP types: EAP-TLS (previously tested)
The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2, also called RSN (Robust Security Network). 802.11i makes use of the Advanced Encryption Standard (AES) block cipher, whereas WEP and WPA use the RC4 stream cipher.
New certification programs allow newer technology and specifications come into the marketplace. These certification programs may be mandatory (e.g., WPA2 ) or optional (e.g., WMM ). The Wi-Fi Alliance definition of interoperability demands that products have to show satisfactory performance levels in typical network configurations and have to ...
In addition, the IEEE 802.11 WG noted that the functionality offered by WAPI systems was equivalent to only a small subset of the security offered by WPA2-based systems. The China NB eventually withdrew WAPI in October 2011 (document JTC1/SC6 N15030) and the project was formally cancelled by SC6 in February 2012.
WPA2 has been found to have at least one security vulnerability, nicknamed Hole196. The vulnerability uses the WPA2 Group Temporal Key (GTK), which is a shared key among all users of the same BSSID, to launch attacks on other users of the same BSSID. It is named after page 196 of the IEEE 802.11i specification, where the vulnerability is discussed.
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
The CWNE credential is the final step in a four-level certification process. It validates the applicant's real-world application of the principles covered by the other CWNP certification exams, including wireless protocol analysis, security, advanced design, spectrum analysis, wired network administration, and troubleshooting.
The standard also includes WPA2 security and features to control access within corporate networks. [9] Wi-Fi Direct-certified devices can connect one-to-one or one-to-many and not all connected products need to be Wi-Fi Direct-certified. One Wi-Fi Direct enabled device can connect to legacy Wi-Fi certified devices.
