<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Please find attached the version 1.5 of the Extended Procedures. I am really sorry I was not able to do this earlier but I had a rather difficult summer due to personal issues and a launch that
I had to support just now (Sentinel 5p). I will try to also work on the EP Green Book action I have but I cannot make any promises.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Gilles, you would need to still update the FSR part.</span>

<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">It was agreed that master keys should only be explicitly required in the OTAR. In the previous version, also the Key Verification procedure was referring to the use of a master key. This has been
changed and the procedure now just talks about a "key protection key" that can be either a master or a session key</span>

<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">ARC: Added ARC to the Rekey SA procedure as a mandatory, managed field. In the baseline mode, as agreed, its 64 bit. Please note that the data structure pictures in Sections 5.5.1.3 (Rekey SA)
and 7.1.1.3 (Rekey SA Baseline Mode) still require update since the document contains only image files for them an not the Visio sources (<b>@Craig</b>, could you please provide them to me?).</span>

<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Unique Identification of Sender and Receiver VCs: This is addressed now by new clauses 5.3.2.2.2.3.3 and 5.3.2.2.2.3.4,
