User's Manual

Point Protocol's (PPP) authentication protocol and provides a generalized
framework for several different authentication methods. EAP is supposed
to head off proprietary authentication systems and let everything from
passwords to challenge-response tokens and public-key infrastructure
certificates all work smoothly.
EAP-AKA
EAP-AKA (Extensible Authentication Protocol Method for UMTS
Authentication and Key Agreement) is an EAP mechanism for
authentication and session key distribution, using the Universal Mobile
Telecommunications System (UMTS) Subscriber Identity Module
(USIM). The USIM card is a special smart card used with cellular
networks to validate a given user with the network.
EAP-FAST
EAP-FAST, like EAP-TTLS and PEAP, uses tunneling to protect traffic.
The main difference is that EAP-FAST does not use certificates to
authenticate.
Provisioning in EAP-FAST is negotiated solely by the client as the first
communication exchange when EAP-FAST is requested from the server.
If the client does not have a pre-shared secret Protected Access
Credential (PAC), it can request to initiate a provisioning EAP-FAST
exchange to dynamically obtain one from the server.
EAP-FAST documents two methods to deliver the PAC: manual delivery
through an out-of-band secure mechanism, and automatic provisioning.
 Manual delivery mechanisms can be any delivery mechanism that
the administrator of the network feels is sufficiently secure for
their network.
 Automatic provisioning establishes an encrypted tunnel to protect
the authentication of the client and the delivery of the PAC to the
client. This mechanism, while not as secure as a manual method
may be, is more secure than the authentication method used in
LEAP.
The EAP-FAST method can be divided into two parts: provisioning, and
authentication. The provisioning phase involves the initial delivery of the
PAC to the client. This phase only needs to be performed once per client
and user.
EAP-GTC
The EAP-GTC (Generic Token Card) is similar to the EAP-OTP except
with hardware token cards. The request contains a displayable message,
and the response contains the string read from the hardware token card.
EAP-OTP
EAP-OTP (One-Time Password) is similar to MD5, except it uses the
OTP as the response. The request contains a displayable message. The
OTP method is defined in RFC 2289.
