EAP-Type & Encryption: Security settings. These settings allow you to enhance the 

security of data across the wireless LAN. Refer to “EAP Credentials” on page A-5 and 

“SCU Security Capabilities” on page A-4 for details about these settings.

The SCU provides integrated security to protect transmitted data as well as the hand-held 
and wireless WAN infrastructure that transmit and receive data.
A foundational element of the IEEE 802.11i WLAN security standard is IEEE 802.1X and a 
critical application on a mobile device is an 802.1X supplicant. This supplicant provides an 
interface between the radio and the operating system and supports the authentication and en-
cryption elements required for 802.11i, also known as Wi-Fi Protected Access 2 (WPA2), as 
well as predecessors such as WPA and WEP. Summit software includes an integrated suppli-
cant that supports a broad range of security capabilities, including:
•

802.1X authentication using pre-shared keys or an EAP type, required for WPA2 and 

WPA.

•

Data encryption and decryption using WPA2 AES, WPA TKIP or WEP.

Common EAP types include:
•

EAP-TLS: Uses the same technology as a follow-on to Secure Socket Layer (SSL). It 

provides strong security, but relies on client certificates for user authentication.

•

PEAP: Provides secure user authentication by using a TLS tunnel to encrypt EAP traf-

fic. Two different inner methods are used with PEAP:

Credentials

Authentication credentials for the 
selected EAP type.
Refer to “EAP Credentials” on 
page A-5.

User: Username or 
Domain/Username (up to 64 
characters).
Password: up to 64 characters.
For PEAP: CA Cert–CA server 
certificate filename.

None

Encryption

Type of encryption used to protect 
transmitted data.

Off, Manual WEP, Auto WEP 
(generated during EAP authenti-
cation), WPA-PSK, WPA-TKIP, 
WPA2-PSK, WPA2-TKIP, 
WPA2-AES, CCKM-TKIP.
For Manual WEP: Up to four
static WEP keys.
For PSK: ASCII passphrase or 
hex PSK.
