19. L G 162 User s Guide Appendix B Types of EAP Authentication This appendix discusses the five popular EAP authentication types EAP MDS EAP TLS EAP TTLS PEAP and LEAP The type of authentication you use depends on the RADIUS server Consult your network administrator for more information EAP MD5 Message Digest Algorithm 5 MDS authentication is the simplest one way authentication method The authentication server sends a challenge to the wireless station The wireless station 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 MDS 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 stations 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
20. 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 management overhead EAP TTLS Tunneled Transport Layer Service EAP TTLS is an extension of the EAP TLS authentication that uses certificates for only the server side authentications to establish a secure connection Client authentication is then done by sending username and password through the secure connection thus client identity is protected For client authentication EAP TTLS supports EAP methods and legacy authentication methods such as PAP CHAP MS CHAP and MS CHAP v2 PEAP Protected EAP Like EAP TTLS server side certificate authentication is used to establish a secure connection then use simple username and password methods through the secured connection to authenticate the clients thus hiding client identity However PEAP only supports EAP methods such as EAP MD5 EAP MSCHAPv2 and EAP GTC EAP Generic Token Card for client authentication EAP GTC is implemented only by Cisco Types of EAP Authentication iii ZyXEL G 162 User s Guide LEAP LEAP Lightweight Extensible Authentication Protocol is a Cisco implementation of IEEE802 1x For added security certificate based authenticat
