4. Major Changes since predraft5
March 2014
Major Changes since predraft5
Section 5.2
Added in text describing primitives as presented in Jan meeting
KMP_START request, indication, confirm, response
KMP_REKEY request, indication, response, confirm
KMP_DATA request, indication, confirm
KMP_PURGE request, confirm
Naming still uncertain – need guidance from MAC experts
Section 5.3
Replaced figure 4 with figs 4&5 and table 2
Closer to format of other documents

5. Document Todo List Fragmented Data Service Determine primitive naming
March 2014
Document Todo List
Fragmented Data Service
Separate Data primitives into a general fragmented data service rather than include in KMP
Determine primitive naming
Reorder sections to match other documents
5.3.4 IE Content Examples – reformat
Add further sequence diagrams if needed
6 State machines
Add timeout to inbound state machine for lost frag
7 KMP Transport PIBs
Need to revisit how macKmpSecurityRequired is used

6. Input required Architectural questions – James / Ben / Pat

Input required
Architectural questions – James / Ben / Pat
Do we need KMP_START?
Or will the KMP itself initialise the Key Management entities (KME) at either end of the link
i.e. is there an equivalent in the KMP itself so that all the initiating KME needs to do is send the first KMP payload?
Do we need further KMP primitives?
We have START and REKEY – are there any other operations a KME needs to perform
The best way to answer the above is to consider how one of the KMPs in the appendices would actually be implemented.
Paper design should be sufficient
KMP Champions – get scribbling!

7. Next steps Include Tero’s sketch of 15.4 security?
March 2014
Next steps
Include Tero’s sketch of 15.4 security?
Is there an equivalent for 15.7?
Review predraft6 and send comments
Could this be done in next 2 weeks?
Produce a new predraft covering the todo list and comments
We need more input/discussion on the points raised to get them closed more quickly
Regular eg weekly/biweekly calls may help
