Rationale/Explanation of issue:

The current EAP keying framework contains a lot of good information, however
it is somewhat difficult to read and understand.  I believe this is because
it mixes issues that have to do with 802.11, handoff schemes and EAP method
internals without clearly explaining what is expected of the external
behavior of EAP methods.  In addition I think some of the material would be
good to have in a standards track document.

Requested change:

Section 1 - External behavior expected of EAP methods and Frameworks

1.1 - Generated key material: MSK and EMSK
1.2 - Exported key material: MSK, AMSK and AAA-Key
1.3 - Derivation of AMSK from the EMSK
1.4 - Identifying an instance of EAP method execution and naming keys
1.6 - MSK and EMSK lifetime
1.7 - Key Request Considerations
1.8 - Security Considerations

Section 2 - Internal key generation for EAP methods (informative)
Section 3 - Example using keys in ciphering applications such as 802.11i
(informative)
Section 4 - Handoff schemes (informative)

Section 1 could be a document on its own or a normative section of a larger
document.

I will gladly help restructure the document or work on a separate document
along these lines if this is the direction the working group wants to go.
