March 2014 Document Status Latest predraft posted to the private area of document server Two versions – clean copy and with change tracking predraft6_P802-15-9_Draft_Standard_clean.pdf predraft6_P802-15-9_Draft_Standard_changes.pdf Incorporates Comments on predraft5 Formatting changes for consistency with other 802.15 docs Major additions to primitives section Questions on points raised as the predraft was being created Highlighted in yellow in both versions Paul Chilton, NXP Semiconductors

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 802.15 documents Paul Chilton, NXP Semiconductors

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 802.15 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 Paul Chilton, NXP Semiconductors

Input required Architectural questions – James / Ben / Pat March 2014 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! Paul Chilton, NXP Semiconductors

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 Paul Chilton, NXP Semiconductors
