9.4 Security

The SimpleLink™ Wi-Fi

®

CC3220MODx and CC3220MODAx internet-on-a chip modules enhance the security

capabilities available for development of IoT devices, while completely offloading these activities from the MCU
to the networking subsystem. The security capabilities include the following key features:

Wi-Fi and Internet Security:

• Personal and enterprise Wi-Fi security

– Personal standards

• AES (WPA2-PSK)
• TKIP (WPA-PSK)
• WEP

– Enterprise standards

• EAP Fast
• EAP PEAPv0/1
• EAP PEAPv0 TLS
• EAP PEAPv1 TLS EAP LS
• EAP TLS
• EAP TTLS TLS
• EAP TTLS MSCHAPv2

• Secure sockets

– Protocol versions: SSL v3, TLS 1.0, TLS 1.1, TLS 1.2
– Powerful crypto engine for fast, secure Wi-Fi and internet connections with 256-bit AES encryption for TLS

and SSL connections

– Ciphers suites
