<p class="MsoNormal">Great meeting. Looks like we are making progress now. It will be nice to get this behind us.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Since the change will impact the CAs, we need the ballot to have an effectivity date. As such, we need to keep the current requirements as is with no change. We will also add in the new requirements and have them be effective on a future
date. It is understood that the CAs may implement the requirement before that date.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Attached is a draft with the idea. I used the latest version of the CSBRs and captured most of the changes.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It would be great, if the CAs could provide some feedback on an effective date.<o:p></o:p></p>

<p class="MsoNormal">Thanks for the proposal. Please find your document with some edits. I wanted to state that the subscriber could use a Signing Service to protect the private key. In addition I tried to reduce the number of $B!H(BFIPS 140-2 Level 2 or Common
Criteria EAL 4+$B!I(B call outs as I am sure they will not remain consistent.<o:p></o:p></p>
