ZyXEL G-270S User’s Guide P P E N D I X Types of EAP Authentication This appendix discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP- TTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information. -
Page 76: Table 27 Comparison Of Eap Authentication Types
ZyXEL G-270S User’s Guide 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. - Page 77 ZyXEL G-270S User’s Guide WPA(2) User Authentication WPA or WPA2 applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless stations using an external RADIUS database.
