F-2 Types of EAP Authentication
hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5 and EAP-
MSCHAPv2, for client authentication.
For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys
for data encryption. They are often deployed in corporate environments, but for public deployment, simple
user name and password pair is more practical. The following table is a comparison of the features of four
authentication types.
