Government CAs in the Microsoft Root Program

1 Reply

Microsoft was the first Root program in a browser to have an open and transparent process for becoming a CA as well as the first to have public policy, audit and technical requirements that CAs must comply with.

Today while the other browsers have joined on and even raised the bar significantly Microsoft continues to operate their root program in an open and clear way.

One example of this is the list they publish of the companies who meet their requirements; you can see this list here.

There are a number of interesting things we can gleam from this list; one of them is how many governments have their own certificate authorities.

For example as of March 11, 2011 we know that there are a total of 46 government owned and operated “Root Certificates” in the Microsoft Root Program, these include:

With a closer look we see that these 46 certificates are operated by 33 different agencies in 26 countries.

 

Wikipedia tells us there are 207 governments and now we know apparently 14% of them operate their own globally trusted root.

 

Though I love to travel and I consider myself a citizen of the world I have never needed to communicate with any of these governments using their private PKIs so I personally have marked them as “revoked” in CryptoAPI, I also manage which of the commercial root CAs I trust manually.

There are some other interesting observations we can gleam from the Root Program membership also, I will do more posts on these later.

Serving OCSP POST responses on a CDN

Leave a reply

The other day I did a blog post on how we are using a CDN to front our OCSP services, the CDN we are using is CloudFlare who is one of our partners.

In that blog post I mentioned that POSTs requests from an OCSP client would normally be a cache miss for a CDN and this introduces additional latency in serving these responses.

Even though the response times we were getting had this additional latency the performance was still acceptable but we wanted to do better so a few weeks ago I went to the CloudFlare office and worked with them on making their services OCSP aware.

Specifically we made it so that when they get an OCSP POST they can determine what cached response to return (for example from a prior GET) instead of going back to our responders to have our responder do that for them.

As of today this change has gone live, as you know I love numbers which is why I have been publishing these repository performance numbers. What you will see if you look at those is that our worldwide average is right around 100ms, if we take out china and Australia that figure drops to around 60ms.

The problem with these numbers is they only test the GET variant of the protocol, that is because neither Pingdom nor Monitis let me simulate binary POSTs (which is what the OCSP POST variant looks like).

With that said we can extrapolate what the numbers look like fairly easily; from my current network location (which is slow) this is what I see:

 

 

What I want you to notice here is that over 15 requests when I do a POST to the CDN instance of our responder I get the same response time average as I do when I perform the same test with the GET variant.

What this tells us is that POST is performing the exact same as a GET which from this we can safely say that in our case the performance numbers I have been publishing for GET are also accurate for POSTs.

What you will also see that our responder is slower to server via POST, this is because it is designed around nonced OCSP requests and as such isn’t optimized as much as it could be for caching them.

I should also note that our decision to put a CDN in front of our OCSP responder does not break clients that want to send nonced requests (no browsers do by default btw), these are simply treated as a cache miss.

Title: Senior Software Engineer (Front-End)

Location: Greater Seattle Area

Languages: English

 

Who we are

GlobalSign was formed in 1996 as one of the Internet’s original trust service providers (you probably know us as a Certificate Authority). Over the years we have issued millions of digital certificates that have been used to secure commerce and communication on the Internet. Our solutions take the pain out of using cryptography and help organizations solve complex problems with increased productivity and peace of mind.

 

What we’re going to do

The web has changed a lot since 1996 but how we bootstrap trust on it has not changed much – we are going to fix that.

 

Who we’re looking for

We are building a small engineering team here in the Seattle area and need a senior developer who is passionate about security and creating beautiful user experiences. In this role you’ll be able to use your experience to help us recruit new team members and build our engineering team to into a powerhouse.

We want someone who feels someone who feels comfortable on both the front- and back-end, who loves learning new stuff, who’s entrepreneurial, a technical leader, a true creative problem solver.

You’ll have experience with security technologies but your background will be focused on building experiences that bridge the gap between user needs and technology requirements. You’ll also have experience building fault-tolerant, high performance, and highly scalable systems.

 

Skills & Experience

  • HTML/CSS/Javascript (jQuery, AJAX, etc.) master with a healthy interest in HTML5, REST and JSON.
  • Experience with one or more server-side languages and frameworks especially Java, Node.js and PHP.
  • Experience designing highly interactive web applications with performance, scalability, usability, and security in mind.
  • Experience with relational database schema design and queries.
  • Experience developing software on Unix/Linux.
  • Love your version control (Git preferably).
  • Understanding of applied cryptographic concepts such as certificates, certificate chains, key management.
  • Understanding of security risks and secure software development.
  • Enjoys prototyping and iterating stuff.Bonus points for speaking Japanese.

 

Required Qualifications

  • 5 years dynamic / scripting language programming, with background in C/C++ systems programming preferred.
  • 2+ years experience in Systems Engineering / Administration with firm understanding of *nix architecture.
  • Strong Computer Science fundamentals (data structures and algorithms).
  • Bachelor’s degree in Computer Science, or equivalent experience. Engineering or related discipline highly recommended.
  • Awesomeness trumps all other requirements.

How to seed the CryptoAPI URL cache with an OCSP response

Leave a reply

It is possible to “staple” an OCSP response into higher level protocols such as TLS. This concept has been supported in Windows since Windows VISTA, shortly after it was added to OpenSSL/Apache and soon it will also be in Nginx.

When “stapling” is used the subscriber (the web server in the TLS case) requests the status of his own certificate from the OCSP responder his CA operates to get a time valid OCSP response for his own certificate.

Since the OCSP response is signed by the CA it can be relayed by the web server for the duration in which that OCSP response is time valid to save the client of the web server (the relying party, aka the browser) the need to make an additional socket connection back to the CA.

This has both performance and privacy benefits.

You can apply the same concept to other PKI related protocols/applications as well, for example in a document signing application like Adobe Acrobat. In such an application the subscriber might sign the document, timestamp it using a timestamp protocol like RFC 3161 and then attach a time valid OCSP response to it so that the document is verifiable at a later date.

This scenario is important not only for its performance and privacy benefits but because it is a practical necessity because CAs do not typically maintain revocation information (OCSP responses and CRLs) for expired certificates.

By stapling the OCSP response to the signed and time-stamped document the relying party can verify the signature, the certificates and the revocation status of the certificates in the context of the timestamp that was attached to the document.

But how do you do that with CryptoAPI?

It’s actually pretty straight forward, as the relying party when you call CertGetCertificateChain to validate the associated certificate you need to:

  1. Once you have verified your timestamp is cryptographically valid and trusted, take the time it and pass it in as pTime.
  2. On the CERT_CONTEXT there is a CERT_INFO structure that contains an array of CERT_EXTENSION, here you create an extension of type CERT_OCSP_RESPONSE_PROP_ID and in there you put a basic signed OCSP response .

When CryptoAPI does the chain validation it will try to use the OCSP response you passed in, if it finds a problem with the provided response it may go online to get a new one that is “OK”.

This online behavior can be controlled by indicating to CertGetCertificateChain you do not want online revocation checking (see CERT_CHAIN_REVOCATION_CHECK_CACHE_ONLY).
