AAAarch Framework ? Security Associations

* Slide showing user, AAA, and application with preexisting SA and business association and relational SA and business association.

o Use preexisting to create “relational” [wrong term]
* Add CA or KDC to the model.

* Add a broker between AAA and application

o How do user and application know what an authorization belongs to?  (binding problem, use of keys)
* Three way exchange
o 802.11i project
o Jesse Walker and others
o Supplicant-initiated key passing
* John mapped the exchange to pull model

* Work item

o Take Chesson model and apply to AAAarch models (push/pull/agent)
o Apply also to roaming/broker model
o Include auditing (proving who asked, who authorized)

* Questions

o Model from application point of view.  Using Keynote2(?) you could use authorization certificates.  [not sure I have this right]
