TTLS
Tunneled Transport Layer Security. An Extensible Authentication Protocol (EAP) method
developed by Funk Software, Inc., and Certicom for 802.1X authentication. TTLS uses a
combination of certificates and password challenge and response for authentication. The
entire EAP subprotocol exchange of attribute-value pairs takes place inside an encrypted
transport layer security (TLS) tunnel. TTLS supports authentication methods defined by
EAP, as well as the older Challenge Handshake Authentication Protocol (CHAP), Password
Authentication Protocol (PAP), Microsoft CHAP (MS-CHAP), and MS-CHAPV2. Compare

tunneling
The transmission of data by one network through the connections of another network by
encapsulating its data and protocol information within the other network’s transmission
units. To forward traffic for a roaming user, a DWS-1008 switch that is not a member of the
user’s virtual LAN (VLAN) creates a tunnel to another switch on which the user’s VLAN is
configured.
