Lack of evidence sometimes, to provide notice others. Sometimes its getting 
ahold of the person requesting revocation for some reason. Here are the reasons 
and some of the things we’ve seen. Sometimes we can tell just by looking but a 
lot of allegations we get involve a more thorough investigation: 

 

1. The Subscriber requests in writing that the CA revoke the Certificate; 

- Need to contact the subscriber to confirm this was indeed requested. 
Sometimes these just come through a general alias so figuring out if it was the 
subscriber takes a bit of work. 

 

2. The Subscriber notifies the CA that the original certificate request was not 
authorized and does not retroactively grant authorization; 

-  Again, need to contact the subscriber to confirm. Especially if this was 
alleged somewhere on a website rather than the through the designated channels. 

 

3. The CA obtains evidence that the Subscriber’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; 

- TBH, this one is the easiest to confirm as it requires evidence of the key 
compromise. Investigations on this one are doable in a shorter time period.

 

4. The CA obtains evidence that the Certificate was misused; 

- Misuse depends on the circumstances. Usually requires investigation about the 
use with the subscriber.

 

5. 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; 

- Again, requires investigation on what is actually being done. What section 
did they breach? Usually this involves legal on both sides and is a pain in the 
butt. It never concludes within 24 hours (or even 5 days).

 

6. 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); 

- Requires confirmation with the court/licensing service. If this is a 
registrar, expect a super long response time. 7 days would be a boon.

 

7. The CA is made aware that a Wildcard Certificate has been used to 
authenticate a fraudulently misleading subordinate Fully-Qualified Domain Name; 

- Requires involvement of the subscriber to see what happened.

 

8. The CA is made aware of a material change in the information contained in 
the Certificate; 

- We’re made aware of this a lot (change in name, address, etc). Usually it 
requires investigation with a government entity or with the company itself.

 

9. 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; 

- Often straight-forward but sometimes it can involve a good deal of 
investigation into logs. This one usually doesn’t take us more than a couple of 
hours though.

 

10. The CA determines that any of the information appearing in the Certificate 
is inaccurate or misleading; 

- This is hard one to determine sometimes but it doesn’t often involve the 
customer.

 

11. The CA ceases operations for any reason and has not made arrangements for 
another CA to provide revocation support for the Certificate;

- Never see this happen

 

12. 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; 

- Sort of happened with Symantec. However they made arrangements to continue 
maintaining the repository.

 

13. The CA is made aware of a possible compromise of the Private Key of the 
Subordinate CA used for issuing the Certificate; 

- This hasn’t happened in my experience

 

14. Revocation is required by the CA’s Certificate Policy and/or Certification 
Practice Statement; or 

- I don’t know of any CPS that goes beyond these requirements for TLS certs. 

 

15. The technical content or format of the Certificate presents an unacceptable 
risk to Application Software Suppliers or Relying Parties (e.g. the CA/Browser 
Forum might determine that a deprecated cryptographic/signature algorithm or 
key size presents an unacceptable risk and that such Certificates should be 
revoked and replaced by CAs within a given period of time).

- This one isn’t an issue either. By the time something passes with the BRs, 
every CA is well aware of the need to migrate.

I’m surprised no one has given any examples yet. There are a lot of them if you 
go through the revocation requests:

1.      Certs reported on a long weekend where we can’t reach anyone at the 
organization. You’re looking at 4 days there in the US sometimes. Outside of 
the US there can be up to a week or so where response are difficult (especially 
in Europe and China)

I think it's worth understanding why it's important/necessary to obtain contact 
with the organization. Is it because you lack evidence, or to provide notice? I 
think there's a significant difference between these two.

 

1.       
2.      See the Blizzard cert that we had to revoke. (Although this mixes 
investigation with revocation timelines)

Right, I'm aware of what you're referencing, but I'm not sure I see how it 
relates. Could you elaborate on what you see here? I thought the investigation 
was fairly cut and dry.

 

1.       
2.      Sometimes we get requests for revocation through third parties alleging 
key compromise without proof. Takes a while for them to generate a CSR and send 
it over.

Sure, but don't you think it's fair to say the CA hasn't obtained evidence of 
revocation? And if the reporter disagrees with the CA's assessment (about 
whether the evidence constitutes proof of compromise), they at least have a 
response from the CA's investigation and determination that they can then 
discuss, and understand publicly whether the CA's made a mistake in that 
assessment, and how to improve the controls around that.

 

1.       
2.      Emails about cert misuse on sites that contain wares or similar items 
can take 7 days to figure out whether it is indeed  phishing or something 
similar.

A solution there is don't revoke certs for content ;)

 

1.       

 

I’d have to dig out the exact emails on each off these to send over, but 7 days 
for investigation is pretty short unless we get a copy of the private key in 
the first go-around from the reporting entity.

Per Mike’s items:

 

1.      7 days would be preferable as this would provide a “business week” for 
the CA to investigate the issue. It will also provide 2 extra days to have 
reach and discuss the issue with the Reporter and the Subscriber.

As Mike summarized correctly, Google felt and feels that 7 days is too long. We 
repeatedly asked for specific examples and details of where the additional time 
would be valuable, and to date, no CA has provided them. We had previously 
proposed that anything longer should require a mandatory public, unredacted 
incident report from the CA, and the concession to avoid such a requirement was 
to find a balance, while also ensuring that CAs were gathering and collecting 
concrete reports to provide that.

 

2.      Given the examples for unacceptable risk, I would assume that this item 
would have a deadline set in the BRs. We have done this before with 
non-registered domain name certificates. So if the certificate has not been 
revoked by the deadline, then it must be revoked immediately. As such, perhaps 
this requirement should be better defined and also moved to the 24 hour section.

3.      I do agree that the CA should work with both the Reporter and the 
Subscriber; however, please note that the investigation may mean that the 
certificate will not be revoked. Also, having a preliminary report within 24 
hours may not be feasible to have a report with substantial substance as there 
may not be time to discuss with the Subscriber. I do suggest that within 24 
hours the CA should advise the Reporter and the Subscriber that an 
investigation has started which may result in the certificate being revoked.

I don't think this is something we'd agree on. As noted above, our goal is to 
improve the transparency. There are some who've said that the best solution to 
these issues is to know what it's like by going to work for a CA. Absent 
changing employers, the next best thing is going to be to improve the 
transparency of the ecosystem, which will improve the trust overall. CAs are 
already required to conduct their activities within 24 hours - this doesn't 
relax that particular item, but allows them to make it available as a report, 
while offering greater flexibility. That seems a meaningful compromise to 
balance the need for transparency while providing CAs and Subscribers some 
degree of flexibility.

 

 

 

Thanks, Bruce.

Hi all.  Some areas of clarification requested from the Microsoft team:

 

*       I don’t remember why 5 days was chosen vs. 7 or 3 days.  I believe it 
was we felt 7 days was too long but 5 days was reasonable.  I believe we also 
considered the scenario where an incident occurs on a Friday evening of a three 
day weekend and the difficulty of the CA dealing with a subscriber who may be 
unavailable over a weekend for a non-urgent revocation requirement.  5 days 
covered that scenario without being too far past 24 hours.  3 days was felt to 
be too short and 7 days seemed too long.  Correct?
*       Regarding point 11. Will this "given period of time" means up to 5 days 
as well?  Point 11 reads: “The technical content or format of the Certificate 
presents an unacceptable risk to Application Software Suppliers or Relying 
Parties (e.g. the CA/Browser Forum might determine that a deprecated 
cryptographic/signature algorithm or key size presents an unacceptable risk and 
that such Certificates should be revoked and replaced by CAs within a given 
period of time)”
*       There is also a bit of confusion about the following statement as it is 
still governed by the 5 day requirement so we’re not sure why it’s called out 
this way.  “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 to establish a 
date by which the CA will revoke the certificate.”  Should this be clarified to 
include both the reporter and the Subscriber included in both steps to reduce 
potential impact to relying parties.  Perhaps add more clarification in this 
statement: 

*       Report back the findings to reporter and the Subscriber within 24 hours
*       Work with the reporter and the Subscriber to revoke within 5 days

 

Thanks, Mike

Tim,

 

I agree that Vulnerability is different from key compromise and the actions we 
take should reflect that and I think we should try to keep 12 and 13 type 
events in the 5-day list.

 

Is our strategy to have vulnerabilities fall into the 5 day list and exploited 
vulnerabilities fall into the 24 hour list?

Key Compromise: A Private Key is said to be compromised if:

1)      its value has been disclosed to an unauthorized person

2)      an unauthorized person has had access to the private keys

3)      a vulnerability has been exploited to disclose private keys

And the remainder of the definition can be removed because those are examples 
of vulnerabilities being exploited ( Debian weak  and poor key generation).  If 
we want a list of possible vulnerabilities or bad practices, then we can put in 
an appendix.

 

I think #13 is a special case of #12 (both vulnerabilities), so I still 
recommend removing it.  Is the distribution of a private key in in a software 
package any different than the distribution of a private key in any other 
(insecure) method?  

 

Here’s what I’d recommend:

 

a) Use the new definition I listed above

 

b) change:

12. The CA is made aware of a vulnerability that exposes the Subscriber's 
Private Key to compromise; or

to

12. The CA is made aware of a vulnerability that has been exploited to disclose 
the Subscriber's Private Key; or

 

c) Delete #13

Vulnerability is different from key compromise.  Replacing all the heartbleed 
certificates within 24 hours would have been a huge fire drill.  It’s important 
to get them replaced as quickly as possible, but mandatory revocations within 
24 hours is going to make things worse, not better.

 

There are potential mitigating factors for a vulnerability.  For example, the 
technical details may not be publicly known yet, or there may be no public 
exploit available yet.  The vulnerability might not affect all OS versions, 
might be easily blocked by firewalls, and so on.  The amount of effort 
necessary to turn a vulnerability into a key compromise can vary from 
insignificant to “lots and lots”.

 

A compromised key, on the other hand, is clearly compromised.

This has the potential to cause confusion, so I'd like to attempt to fix it. 
Given that a reasonable interpretation of the existing definition of key 
compromise encompasses reasons 12 and 13, but I want to leave those two reasons 
in the document for the sake of clarity as Ryan suggests, maybe I should just 
move those two up to the 24-hour section? I could also be persuaded that a 
vulnerability is different than proof of key compromise, in which case 12 could 
stay in the 5-day section and we could move "or there exists a practical 
technique by which an unauthorized person may discover its value" from the 
definition of key compromise to 12. What do others think?

If  “Subscriber's Private Key is being publicly distributed in a software 
package”, isn’t that the same as #3: “obtains evidence that the Subscriber's 
Private Key corresponding to the Public Key in the Certificate suffered a Key 
Compromise”? 

 

How do you see #12 in reality?  What types of vulnerabilities do you envision 
that could expose a subscribers Private Key that are not also consistent with 
#3?

 

While this is the same argument that I've made in the past, I think the goal 
here is to reduce ambiguity for those that might take a tortured reading of the 
text.

 

For example, at least one vendor 'obfuscated' the private key within their 
binary, requiring running the embedded private key through a transformation (I 
hesitate to say decryption, since the passphrase was itself fixed within the 
binary). Such a vendor might argue that the key has not been compromised until 
someone reverses the binary. This resolves that ambiguity by saying that the 
distribution within the binary itself constitutes a compromise, regardless of 
whether a passphrase is used.

 

Also, the definition of Private Key Compromise is very broad, and the scenarios 
in #12 and #13 would appear to fall into “Key Compromise” which further causes 
confusion about them.  What constitutes a “practical technique”?  If we applied 
this definition to #12 and #13, wouldn’t these all fall into the 24 hour rule?

 

Key Compromise: A Private Key is said to be compromised if its value has been 
disclosed to an unauthorized person, an unauthorized person has had access to 
it, or there exists a practical technique by which an unauthorized person may 
discover its value.  A Private Key is also considered compromised if methods 
have been developed that can easily calculate it based on the Public Key (such 
as a Debian weak key, see http://wiki.debian.org/SSLkeys 
<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwiki.debian.org%2FSSLkeys&data=02%7C01%7CMike.reilly%40microsoft.com%7Ccc86f18ac7f1436d776808d606dd9e4f%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636703946261915965&sdata=VTjxlqVQj%2F5CEUKsG10UF2UoC75AtmFi3d51%2Fj9wdZ4%3D&reserved=0>
 ) or if there is clear evidence that the specific method used to generate the 
Private Key was flawed.

This begins the formal discussion period for ballot SC6.

 

==========================================

 

Ballot SC6: Revocation Timeline Extension

 

Purpose of Ballot:

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:

* 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.

* 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."

* 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.

* 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.

* It requires CAs to disclose their problem reporting mechanisms in a standard 
location: CPS section 1.5.2.

* 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 to establish a date by which the 
CA will revoke the certificate.

 

The following motion has been proposed by  Wayne Thayer of Mozilla and endorsed 
by Tim Hollebeek of DigiCert and Dimitris Zacharopoulos of Harica.

 

--- 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:

** Modify Section 4.9.1.1 to read as follows: **

The CA SHALL revoke a Certificate within 24 hours if:

1. The Subscriber requests in writing that the CA revoke the Certificate;
2. The Subscriber notifies the CA that the original certificate request was not 
authorized and does not retroactively grant authorization;
3. The CA obtains evidence that the Subscriber's Private Key corresponding to 
the Public Key in the Certificate suffered a Key Compromise; or
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.

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:

1. The Certificate no longer complies with the requirements of Sections 6.1.5 
and 6.1.6;
2. The CA obtains evidence that the Certificate was misused;
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;
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);
5. The CA is made aware that a Wildcard Certificate has been used to 
authenticate a fraudulently misleading subordinate Fully-Qualified Domain Name;
6. The CA is made aware of a material change in the information contained in 
the Certificate;
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;
8. The CA determines that any of the information appearing in the Certificate 
is inaccurate;
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;
10. Revocation is required by the CA's Certificate Policy and/or Certification 
Practice Statement;
11. The technical content or format of the Certificate presents an unacceptable 
risk to Application Software Suppliers or Relying Parties (e.g. the CA/Browser 
Forum might determine that a deprecated cryptographic/signature algorithm or 
key size presents an unacceptable risk and that such Certificates should be 
revoked and replaced by CAs within a given period of time);
12. The CA is made aware of a vulnerability that exposes the Subscriber's 
Private Key to compromise; or
13. The CA is made aware that the Subscriber's Private Key is being publicly 
distributed in a software package.

** Modify section 4.9.3 as follows: **

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.

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.

** Modify section 4.9.5 to read as follows: **

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.

After reviewing the facts and circumstances, the CA SHALL work with any entity 
reporting the Certificate Problem Report or other revocation-related notice to 
establish a date when the CA will revoke the Certificate which 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:

1. The nature of the alleged problem (scope, context, severity, magnitude, risk 
of harm);
2. The consequences of revocation (direct and collateral impacts to Subscribers 
and Relying Parties);
3. The number of Certificate Problem Reports received about a particular 
Certificate or Subscriber;
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
5. Relevant legislation.
