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.
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 the authentication types.
