How does EAP PEAP work?

How does EAP PEAP work?

PEAP is similar in design to EAP-TTLS, requiring only a server-side PKI certificate to create a secure TLS tunnel to protect user authentication, and uses server-side public key certificates to authenticate the server. It then creates an encrypted TLS tunnel between the client and the authentication server.

How SSL handshake happens step by step?

The Standard SSL Handshake

1. Client Hello. Information that the server needs to communicate with the client using SSL.
2. Decryption and Master Secret. Server uses its private key to decrypt the pre-master secret.
3. Server Hello.
4. Encryption with Session Key.
5. Authentication and Pre-Master Secret.

What is the most secure EAP method?

EAP/TLS
If security is your primary motivator, EAP/TLS is the most secure EAP mechanism, but it requires a PKI deployment for all end users.

What is the most secure EAP?

EAP-TLS. This is the most secure method as it requires certificates from client and server end. The process involves mutual authentication where client validates server certificate and server validates client certificate.

What does client hello handshake message in EAP-TLS mean?

The peer sends an EAP-Response back to the authentication server which contains a “client_hello” handshake message, a cipher that is set for NULL. TLS server_hello handshake message certificate server_key_exchange certificate request server_hello_done.

When do you use EAP-TLS or PEAP with…?

When a client uses PEAP-EAP-MS-Challenge Handshake Authentication Protocol (CHAP) version 2 authentication, PEAP with EAP-TLS authentication, or EAP-TLS authentication, the client accepts the server’s certificate when the certificate meets the following requirements: The computer certificate on the server chains to one of the following CAs:

How does WLC respond to an EAP-TLS start packet?

The supplicant then responds with an EAP-Response Identity. The WLC then communicates the user-id information to the Authentication Server. RADIUS server responds back to the client with an EAP-TLS Start Packet.

What happens during a TLS handshake on the Internet?

TLS is an encryption protocol designed to secure Internet communications. A TLS handshake is the process that kicks off a communication session that uses TLS encryption. During a TLS handshake, the two communicating sides exchange messages to acknowledge each other, verify each other, establish the encryption algorithms they will use,
