<div dir="ltr"><div>Here is version 3 of this ballot, incorporating changes to v2 suggested by Bruce and Ryan (thanks!).</div><div><br></div><div>I noticed that our current bylaws have reverted back to a fixed-length discussion period, so I have changed this version to comply.<br></div><br>==========================================<br><br><div>Ballot SC6 version 3: Revocation Timeline Extension</div><div><br></div>Purpose of Ballot:<br>Section
4.9.1.1 of the Baseline Requirements currently requires CAs to revoke a
Subscriber certificate within 24 hours of identifying any of 15 issues
affecting the certificate. In cases where there is not an immediate
threat of misuse of the certificate, this requirement can cause undue
harm to a Subscriber that isn't capable of replacing the certificate
prior to revocation. This ballot makes a number of improvements to the
revocation rules imposed by the Baseline Requirements:<br>* Primarily,
it creates a tiered timeline for revocations. The most critical
"reasons" still require revocation within 24 hours, but for many others
24 hours becomes a SHOULD and the CA has 5 days before they MUST revoke.<br>*
A new "reason for revocation" was added to address the fact that there
is currently no requirement for CAs to revoke a certificate when
requested by the domain name registrant. After considering some more
specific language that required CAs to follow 3.2.2.4 to validate domain
control, I settled on the following more general "reason": "The CA
obtains evidence that the validation of domain authorization or control
for any Fully-Qualified Domain Name or IP address in the Certificate
should not be relied upon."<br>* Reason #10 states "The CA determines
that any of the information appearing in the Certificate is inaccurate
or misleading;" This ballot removes "or misleading" because that is a
subjective judgement that could effectively be used to justify
censorship, as discussed at length in relation to the "Stripe, Inc of
Kentucky" EV certificates.<br>* Current reasons #11 and #13 were removed
from the section on subscriber certificates because they address cases
where the intermediate and/or root must be revoked, so there isn't much
sense (and some possible harm) in requiring revocation of all the leaf
certs.<br>* It requires CAs to disclose their problem reporting mechanisms in a standard location: CPS section 1.5.2.<br>*
Within 24 hours of receiving a problem report, the CA is now required
to report back to both the entity reporting the problem and the
Subscriber on the CA's findings, and to work with the reporter and
Subscriber to establish a date by which the CA will revoke the
certificate.<br><br>The following motion has been proposed by Wayne
Thayer of Mozilla and endorsed by Tim Hollebeek of DigiCert and Dimitris
Zacharopoulos of Harica.<br>
<br><div>--- MOTION BEGINS ---
This
ballot modifies the “Baseline Requirements for the Issuance and
Management of Publicly-Trusted Certificates” as follows, based on
Version 1.6.0:
</div><div><br></div><div>** Modify the definition of Key Compromise as follows: **</div>Key
Compromise: A Private Key is said to be compromised if its value has
been disclosed to an unauthorized person or an unauthorized person has
had access to it.<br><div><br></div><div>** Modify Section 4.9.1 to read as follows: **
</div><div><br></div><div>4.9.1.1 Reasons for Revoking a Subscriber Certificate<br></div><div><br> </div><div>The CA SHALL revoke a Certificate within 24 hours if one or more of the following occurs:<br></div>1. The Subscriber requests in writing that the CA revoke the Certificate;<br>2.
The Subscriber notifies the CA that the original certificate request
was not authorized and does not retroactively grant authorization;<br>3.
The CA obtains evidence that the Subscriber's Private Key corresponding
to the Public Key in the Certificate suffered a Key Compromise; or<br>4.
The CA obtains evidence that the validation of domain authorization or
control for any Fully-Qualified Domain Name or IP address in the
Certificate should not be relied upon.<br><br>The CA SHOULD revoke a
certificate within 24 hours and MUST revoke a Certificate within 5 days
if one or more of the following occurs:<br>1. The Certificate no longer complies with the requirements of Sections 6.1.5 and 6.1.6;<br>2. The CA obtains evidence that the Certificate was misused;<br>3.
The CA is made aware that a Subscriber has violated one or more of its
material obligations under the Subscriber Agreement or Terms of Use;<br>4.
The CA is made aware of any circumstance indicating that use of a
Fully-Qualified Domain Name or IP address in the Certificate is no
longer legally permitted (e.g. a court or arbitrator has revoked a
Domain Name Registrant's right to use the Domain Name, a relevant
licensing or services agreement between the Domain Name Registrant and
the Applicant has terminated, or the Domain Name Registrant has failed
to renew the Domain Name);<br>5. The CA is made aware that a Wildcard
Certificate has been used to authenticate a fraudulently misleading
subordinate Fully-Qualified Domain Name;<br>6. The CA is made aware of a material change in the information contained in the Certificate;<br>7.
The CA is made aware that the Certificate was not issued in accordance
with these Requirements or the CA's Certificate Policy or Certification
Practice Statement;<br>8. The CA determines or is made aware that any of the information appearing in the Certificate is inaccurate;<br>9.
The CA's right to issue Certificates under these Requirements expires
or is revoked or terminated, unless the CA has made arrangements to
continue maintaining the CRL/OCSP Repository;<br>10. Revocation is required by the CA's Certificate Policy and/or Certification Practice Statement; or<br>11.
The CA is made aware of a demonstrated or proven method that exposes
the Subscriber's Private Key to compromise, methods have been developed
that can easily calculate it based on the Public Key (such as a Debian
weak key, see <a href="http://wiki.debian.org/SSLkeys" target="_blank">http://wiki.debian.org/SSLkeys</a>), or if there is clear evidence that the specific method used to generate the Private Key was flawed.
<br><div><br></div><div>4.9.1.2 Reasons for Revoking a Subordinate CA Certificate</div><div><br></div><div>The Issuing CA SHALL revoke a Subordinate CA Certificate within seven (7) days if one or more of the following occurs:</div>1. The Subordinate CA requests revocation in writing;<br>2.
The Subordinate CA notifies the Issuing CA that the original
certificate request was not authorized and does not retroactively grant
authorization;<br>3. The Issuing CA obtains evidence that the
Subordinate CA's Private Key corresponding to the Public Key in the
Certificate suffered a Key Compromise or no longer complies with the
requirements of Sections 6.1.5 and 6.1.6;<br>4. The Issuing CA obtains evidence that the Certificate was misused;<br>5.
The Issuing CA is made aware that the Certificate was not issued in
accordance with or that Subordinate CA has not complied with this
document or the applicable Certificate Policy or Certification Practice
Statement;<br>6. The Issuing CA determines that any of the information appearing in the Certificate is inaccurate or misleading;<br>7.
The Issuing CA or Subordinate CA ceases operations for any reason and
has not made arrangements for another CA to provide revocation support
for the Certificate;<br>8. The Issuing CA's or Subordinate CA's right to
issue Certificates under these Requirements expires or is revoked or
terminated, unless the Issuing CA has made arrangements to continue
maintaining the CRL/OCSP Repository; or<br>9. Revocation is required by the Issuing CA's Certificate Policy and/or Certification Practice Statement.<br><br><div>** Modify section 4.9.3 as follows: **</div><div><br></div><div>
The
CA SHALL provide a process for Subscribers to request revocation of
their own Certificates. The process MUST be described in the CA's
Certificate Policy or Certification Practice Statement. The CA SHALL
maintain a continuous 24x7 ability to accept and respond to revocation
requests and Certificate Problem Reports.</div><br><div>The CA SHALL
provide Subscribers, Relying Parties, Application Software Suppliers,
and other third parties with clear instructions for reporting suspected
Private Key Compromise, Certificate misuse, or other types of fraud,
compromise, misuse, inappropriate conduct, or any other matter related
to Certificates. The CA SHALL publicly disclose the instructions through
a readily accessible online means and in section 1.5.2 of their CPS.</div><div><br></div><div>** Modify section 4.9.5 to read as follows: **</div><div><br></div><div>
Within
24 hours after receiving a Certificate Problem Report, the CA SHALL
investigate the facts and circumstances related to a Certificate Problem
Report and provide a preliminary report on its findings to both the
Subscriber and the entity who filed the Certificate Problem Report.</div><div><br></div>After reviewing the facts and circumstances, the CA SHALL work with the
Subscriber and any entity reporting the Certificate Problem Report or
other revocation-related notice to establish whether or not the
certificate will be revoked, and if so, a date which the CA will revoke
the certificate. The period from receipt of the Certificate Problem
Report or revocation-related notice to published revocation MUST NOT
exceed the time frame set forth in Section 4.9.1.1. The date selected by
the CA SHOULD consider the following criteria:<br>1. The nature of the alleged problem (scope, context, severity, magnitude, risk of harm);<br>2. The consequences of revocation (direct and collateral impacts to Subscribers and Relying Parties);<br>3. The number of Certificate Problem Reports received about a particular Certificate or Subscriber;<br>4.
The entity making the complaint (for example, a complaint from a law
enforcement official that a Web site is engaged in illegal activities
should carry more weight than a complaint from a consumer alleging that
she didn't receive the goods she ordered); and<br>5. Relevant legislation.<br><div>
