3.2 Wi-Fi Network Security

The Wi-Fi layer of the CC33xx companion IC complies with 802.11 security to maintain the integrity and confidentiality of the frames (L2 data units) in transactions between AP and STA, or between two peers in the case of Wi-Fi direct mode. The security protocols are described in the IEEE 802.11 specifications and the extensions.

The Wi-Fi subsystem of the CC33xx companion IC provides support for both personal and enterprise security paradigms, including RADIUS-based authentication (802.1X).

Important:

Wi-Fi Enterprise is not implemented inside the CC33xx companion IC but externally (for example, Wpa_supplicant and hostapd).

The CC33xx companion IC complies with Wi-Fi Alliance (WFA) security standards and test suites.

Table 3-2 lists the supported Wi-Fi security-related capabilities.
