I am<br>> no longer concerned that this will result in a weakening of the checks of an<br>> applicant's physical existence - which is the key check because it<br>> establishes jurisdiction and it is also the info placed in the cert itself.<br>><br>> The remaining issue for me is this (also raised by Kelvin): how do we decide<br>> what's a good Verified Method of Communication? Which, to me is basically<br>> the question of how secure from interception (as opposed to<br>> eavesdropping) do we want a Verified Method of Communication to be?<br>><br>> It's fairly hard for a non-government to intercept and redirect a letter, or<br>> a call made from a landline phone to another one. Do we have the same level<br>> of confidence about mobile phones, email addresses etc.?<br>> Perhaps we do. I might even have more confidence that, given a Skype<br>> nickname, a Skype call to that nickname would connect with its owner than I<br>> would have confidence that an email sent to an email address would connect<br>> with its owner.<br>><br>> We use unencrypted and unauthenticated email for Domain Validation. But is<br>> that something we want to rely on as our approved mechanism of communication<br>> for EV issuance?<br>><br>> I think this merits further discussion. I'm torn what to do now, as voting<br>> ends today. I think I'll stick with NO, but I would be very open to a<br>> resubmission of this ballot once we've discussed and addressed this question<br>> of what should and shouldn't qualify as a VMC.<br>><br>> Gerv<br>> _______________________________________________<br>> Public mailing list<br>> <a href="mailto:Public@cabforum.org">Public@cabforum.org</a><br>> <a href="https://cabforum.org/mailman/listinfo/public">https://cabforum.org/mailman/listinfo/public</a><br>><br>> _______________________________________________<br>> Public mailing list<br>> <a href="mailto:Public@cabforum.org">Public@cabforum.org</a><br>> <a href="https://cabforum.org/mailman/listinfo/public">https://cabforum.org/mailman/listinfo/public</a><o:p></o:p></p></div></body></html>
