D5 authentication is the simplest one way authentication method The authentication server sends a challenge to the wireless client The wireless client proves that it knows the password by encrypting the password with the challenge and sends back the information Password is not sent in plain text However MD5 authentication has some weaknesses Since the authentication server needs to get the plaintext passwords the passwords must be stored Thus someone other than the authentication server may access the password file In addition it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication Finally MD5 authentication method does not support data encryption with dynamic session key You must configure WEP encryption keys for data encryption EAP TLS Transport Layer Security With EAP TLS digital certifications are needed by both the server and the wireless clients for mutual authentication The server presents a certificate to the client After validating the identity of the server the client sends a different certificate to the server The exchange of certificates is done in the open before a secured tunnel is created This makes user identity vulnerable to passive attacks A digital certificate is an electronic ID card that authenticates the sender s identity However to implement EAP TLS you need a Certificate Authority CA to handle certificates which imposes a manag
