Types of EAP Authentication
LEAP
LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE802.1x.
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, a
simple user name and password pair is more practical. The following table is a comparison of the features
of five authentication types.
