<div>This begins the voting period for ballot <span
class="gmail-il">SC33</span>: TLS Using ALPN Method</div>
<div><br>
</div>
<div>Purpose of Ballot:</div>
<div><br>
</div>
<div>In January 2018, a vulnerability affecting the ACME
TLS-SNI-01 method of domain validation was disclosed [1].
That method is an implementation of BR 3.2.2.4.10, which is
still permitted by the BRs despite the vulnerability. Some
Browsers have banned the use of method 10 unless mitigations
for the vulnerability have been put into place, and one
approach to mitigation - using application-layer protocol
negotiation (ALPN) - has now been standardized by the IETF
as RFC 8737. This ballot replaces the poorly specified and
potentially insecure 'method 10' with a new 'method 20'
based on RFC 8737.</div>
<div><br>
</div>
<div>The ballot proposed no transition period during which
method 10, or validations performed using method 10 may
continue to be relied upon. The only known current use of
method 10 is an implementation of RFC 8737 that would remain
compliant (although it may require changes to the CA's CPS
and the identifier of the method that is being logged when
performing validations).<br>
</div>
<div><br>
</div>
<div>This ballot also limits the use of the new method to the
specific FQDN that was validated - different subdomains
require new validations, and wildcards are not permitted.
This requirement is not the result of a specific known risk
but rather stems from a belief that DNS-based validation
methods are more appropriate for verifying control over an
entire subdomain.<br>
