Configuring EAP-FAST authentication

EAP-FAST is an authentication method that was developed by Cisco Systems. Similar to PEAP authentication, EAP-FAST authentication encrypts EAP transactions within a TLS tunnel. Although PEAP uses a server-side digital certificate to configure the TLS tunnel, EAP-FAST uses a .pac file.

The .pac file that the BlackBerry devices and the authentication server share contains secret keys that are unique to the BlackBerry devices. The EAP-FAST master key on the authentication server generates the .pac file. EAP-FAST uses the .pac file to open the TLS tunnel and authenticates the user credentials through the TLS tunnel.
