Objective (our view)
Reduce DOS attack by preventing unauthorised disconnect (authenticate MAC addresses)
Authenticate and hide information in action frames
Hide station identity

3. Not in Scope (our view) Protecting data frames (beyond what exists)

Not in Scope (our view)
Protecting data frames (beyond what exists)
Protecting control frames (cost outweighs the benefit)
Inventing new key management scheme – protection based on same key hierachy as data frames and authentication frames.
Edney, Faccin, Nokia

4. Nov 2004
Issues to address
Status of management frames which occur before keys are established.
Avoiding deadlock when one party looses keys to a secure session.
Edney, Faccin, Nokia

5. One preliminary concept
Nov 2004
One preliminary concept
Station selects MAC address for session
Station “registers” selected MAC address with AP in secure way
Once registered MAC address is bound to security association
Chosen MAC address is mapped to real MAC address
