3. EAP-TTLS Authentication Method
EAP-TTLS is a product of the cooperation of Funk Software and Certicom. It can provide an
authentication as strong as that provided by EAP-TLS, but without requiring users to have their
own digital certificate. The only request is that the Radius server should have a digital
certificate. The authentication of users’ identity is implemented with passwords transmitted in a
safely encrypted tunnel established via the certificate of the authentication server. Any kind of
authentication request including EAP, PAP and MS-CHAPV2 can be transmitted within TTLS
tunnels.
