Description of Working Group:

The Extensible Authentication Protocol (EAP) [RFC 3748] is a network
access authentication framework used in the PPP, 802.11, 802.16, VPN,
PANA, and in some functions in 3G networks. EAP itself is a simple
protocol and actual authentication happens in EAP methods.

Over 40 different EAP methods exist. Most of this methods are
proprietary methods and only a few methods are documented in RFCs. The
lack of documented, open specifications is a deployment and
interoperability problem. In addition, none of the EAP methods in the
standards track implement features such as key derivation that are
required for many modern applications. This poses a problem for, among
other things, the selection of a mandatory to implement EAP method in
new network access technologies. For example, no standards track methods
meet new requirements such as those posed in RFC 4017, which documents
IEEE 802.11 requirements for EAP methods.

This group is chartered to work on the following types of mechanisms to
meet RFC 3748 and RFC 4017 requirements:

- An update to RFC 2716 to bring EAP-TLS into standards track, clarify
specification, interoperability, and implementation issues gathered over
the years, and update the document to meet the requirements of RFC 3748,
RFC 4017, and EAP keying framework documents.
Backwards compatibility with RFC 2716 is a requirement.

- Enhanced functionality to enable a TLS-based EAP method to support
authentication methods beyond certificates, channel bindings and other
optional functions required in RFC 4017. So as to enable RFC 2716bis to

focus solely on clarifications to the existing protocol, this effort
will be handled in a separate document. Depending on an analysis of the
behavior of existing implementations, it is possible that this effort
may be able to use the existing EAP-TLS type code, or it may need to be
handled via assignment of a new EAP Type Code.

- A mechanism based on strong shared secrets that meets RFC 3748 and RFC
4017 requirements. This mechanism should strive to be simple and compact
for implementation in resource constrained environments.

- A mechanism meeting RFC 3748 and RFC 4017 requirements that makes use
of existing password databases such as AAA databases. The implementation
should strive to be usable in resource constrained environments.

In order to facilitate the development of the shared secret and password
based methods design teams will be formed. The design teams should take
into consideration existing methods including mechanisms based on
EAP-TLS such as TLS-PSK.
