1. IEEE P1619.3 Architecture Subcommittee Conference Call November 15, 2007 1IEEE P1619.3 Architecture Subcommittee

2. Agenda Review Previous Actions “Draft” KM Conceptual Models “Draft” Key Lifecycle Models Items in Progress Next Steps 2IEEE P1619.3 Architecture Subcommittee

3. Previous Action Item Review Mike W. to refine KM conceptual models; integrate into Model Proposal with definitions In progress, models “complete”, working definitions Bob L., Jon H., and Larry H. to collaborate on single key lifecycle model Common model agreed to in concept. Still working some of the finer points. We will discuss a little bit today. 3IEEE P1619.3 Architecture Subcommittee

9. Items in Progress 9IEEE P1619.3 Architecture Subcommittee

10. Items in Progress l What do we do with the key exchange data structures currently defined? l Action: Move to OO and MSG sections l What do we do about Policy definitions and do we need another model? l Action: Yes? l Do we need interaction models for the API and the Message/Transport protocol interface? l Action: Yes… 10IEEE P1619.3 Architecture Subcommittee
