• X.509 Digital Certificates
• Image authentication
• Device authentication
• File authentication
• Signaling authentication
• Secure Cisco Unified SRST
• Media encryption (SRTP)
• Signaling encryption (TLS)
• Certificate authority proxy function (CAPF)
• Secure profiles
• Encrypted configuration files

• Locked network profiles
• Administrator password
Extensible Authentication Protocol – Flexible Authentication via Secure
Tunneling (EAP-FAST)
This client server security architecture encrypts EAP transactions within a Transport Level Security (TLS) tunnel between the
access point and the Remote Authentication Dial-in User Service (RADIUS) server such as the Cisco Access Control Server
(ACS).
The TLS tunnel uses Protected Access Credentials (PACs) for authentication between the client (phone) and the RADIUS
server. The server sends an Authority ID (AID) to the client (Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G),
