Protected Extensible Authentication Protocol (Peap) - Cisco 7925G Deployment Manual

See the "Installing Certificates" section for more information.

Protected Extensible Authentication Protocol (PEAP)

Protected Extensible Authentication Protocol (PEAP) uses server-side public key certificates to authenticate clients by creating
an encrypted SSL/TLS tunnel between the client and the authentication server.
The ensuing exchange of authentication information is then encrypted and user credentials are safe from eavesdropping.
MS-CHAP v2 is the current supported inner authentication protocol (GTC is not supported).
