2017年1月5日 · On EAP-TTLS, you are right again. After the server is securely authenticated to the client via its CA certificate and optionally the client to the server, the server can then use the established secure connection ("tunnel") to authenticate the client. PEAP is an encapsulation, is not a method, but you are almost right again. PEAP is similar in ...

Both EAP-TTLS and PEAP use TLS (Transport Layer Security) over EAP(Extensible Authentication Protocol). As you may know, TLS is a newer version of SSL and works based on certificates signed by a trusted central authority (Certification Authority - CA).

2016年8月29日 · In EAP-TTLS, the tunnel is established with no authentication. Once the tunnel is established and secure communication possible, any means of authentication, such as AD credentials, can be used. The certificate is used to establish a secure connection over a public channel, where the certificate is used to confirm the server's identity.

2020年1月9日 · EAP is an authentication framework, which defines several TLS based methods and encapsulations like EAP-TLS, EAP-TTLS and PEAP. These all require the server/authenticator to have a certificate (EAP-TLS require the client/supplicant to have it too). TLS provides authentication with the use of certificates on its own. Then what is the point of …

2014年10月17日 · I have a few pcaps of traffic for EAP-TTLS conversation, carried by RADIUS. I also have some being carried by EAPoL, but I think the answer to that case might be even less straightforward (though p...

2019年9月4日 · EAP-TTLS forces the RADIUS server to identify itself to a client with a certificate, but optionally a client to the server. All information about an end-user is encrypted through a tunnel. All information about an end-user is encrypted through a tunnel.

2021年6月6日 · I understand that a tls has to be established between the supplicant (end user device) and the auth server but a few things are unclear : How does the supplicant know the ip adress of the auth ser...

2020年10月6日 · In EAP-TLS, the peer (supplicant) and the authenticator do a TLS handshake. In practice, the authenticator usually relays the EAP mesages to an authentication (RADIUS) server which means that the TLS handshake is actually done between the supplicant and the authorization server.

2018年2月8日 · By default, Windows 7 doesn't support EAP-TTLS authentication method natively. If I enable IEEE 802.1X authentication in Windows 7, I can see only two authentication methods: Microsoft smart cards or other certificates; Microsoft: Protected EAP(PEAP)

2019年1月19日 · We have successfully configured EAP-TTLS with valid certificates and set it as default connection method. ( almost all other settings are left to default) However when EAP-TTLS is established, the password is transferred using PAP. I am no network expert but I have read that PAP is not secured and shouldn't be used?
