Question

Which of the following EAP methods is one way authentication only?

A). EAP-FAST
B). EAP- TTLS
C). EAP-TLS
D). EAP-MD5

Answer 1

EAP-MD5 is the EAP method that supports only one-way authentication, while the others support mutual authentication.

Step-by-step explanation:

EAP stands for Extensible Authentication Protocol, which is an authentication framework frequently used in wireless networks. Among the given options, EAP-MD5 is the method that supports only one-way authentication.

EAP-MD5 is considered a weak authentication method because it doesn't provide mutual authentication, meaning the client's identity is verified, but the server's identity is not. This lack of mutual authentication leaves the connection vulnerable to certain attacks.

On the other hand, methods like EAP-FAST, EAP-TTLS, and EAP-TLS support mutual authentication, where both the client and the server verify each other's identity, providing a more secure connection.
