EIC 2024 LogoIdentiverse LogoWe held the second and third of the three planned tenth anniversary celebrations for the completion of OpenID Connect at the 2024 Identiverse conference and European Identity and Cloud Conference. That concludes celebrations in Asia, the Americas, and Europe!

At both Identiverse and EIC, panelists included Nat Sakimura, John Bradley, and myself. Chuck Mortimore joined us at Identiverse. And Torsten Lodderstedt added his perspectives at EIC. We shared our perspectives on what led to OpenID Connect, why it succeeded, and what lessons we learned along the way.

The most common refrain throughout our descriptions was the design philosophy to “Keep simple things simple”. This was followed closely by the importance of early feedback from developers and deployers.

Chuck reached back in time to his OpenID slides from 2011. He reflected on what he was thinking at the time versus what actually happened (and why). Torsten pointed out the importance of cooperation, certification, security analysis, open standards, and an approachable community. At Identiverse, Nat reached back 25 years, examining the intellectual underpinnings and history of OpenID. And at EIC, Nat tackled assertions that OpenID Connect can be complex. John concluded by observing that the OpenID idea is greater than any particular specification.

Our recent OpenID Connect 10th anniversary sessions were:

They build upon the celebration at the OpenID Summit Tokyo 2024.

Thanks to the organizers of all these events for sponsoring the celebrations!

EIC 2024 LogoI was honored to give the keynote presentation Standards are About Making Choices at the 2024 European Identity and Cloud Conference (PowerPoint) (PDF). The abstract was:

When building machines, we take for granted being able to use nuts, bolts, wires, light bulbs, and countless other parts made to industry standards. Standards contain choices about dimensions of screw threads, nut sizes, etc., enabling a marketplace of interoperable parts from multiple suppliers. Without these choices, every part would be custom manufactured. The same is true of the identity and security standards we use to build identity systems.

However, the identity and security standards at our disposal differ wildly in the degree to which they do and don’t make choices. Some consistently define ONE way to do things, resulting in everyone doing it that way (interoperability!). Others leave critical choices unmade, passing the buck to implementers and applications (your mileage may vary).

In this talk, I’ll name names and take prisoners, critiquing existing and emerging standards through the lens of the choices they made and failed to make. Hold on to your hats as we examine the pros and cons of the choices made by OAuth, SAML, X.509, OpenID Connect, Verifiable Credentials, DIDs, WebCrypto, JOSE, COSE, and many others through this lens!

I believe you’ll agree with me that making choices matters.

On March 20, 2024

In CBOR, Claims, Cryptography, Events, IETF, JSON, Specifications

IETF logoMy co-authors and I published updated versions of eight specifications in preparation for IETF 119 in Brisbane. The specifications span three working groups: JOSE, COSE, and OAuth. The updated specifications and outcomes when discussed at IETF 119 are as follows.

1, 2, & 3: JSON Web Proof, JSON Proof Algorithms, and JSON Proof Token. Updates were:

  • Normatively defined header parameters used
  • Populated IANA Considerations sections
  • Allowed proof representations to contain multiple base64url-encoded parts
  • Specified representation of zero-length disclosed payloads
  • Added Terminology sections
  • Updated to use draft-irtf-cfrg-bbs-signatures-05
  • Updated to use draft-ietf-cose-bls-key-representations-04
  • More and better examples
  • Improvements resulting from a full proofreading

Continued reviews and feedback from implementations are requested.

4: Fully-Specified Algorithms for JOSE and COSE. Updates were:

  • Published initial working group document following adoption
  • Added text on fully-specified computations using multiple algorithms
  • Added text on KEMs and encapsulated keys
  • Updated instructions to the designated experts

It was agreed during the JOSE meeting to describe what fully-specified algorithms for ECDH would look like, for consideration by the working group.

5: OAuth 2.0 Protected Resource Metadata. Updates were:

  • Switched from concatenating .well-known to the end of the resource identifier to inserting it between the host and path components of it
  • Have WWW-Authenticate return resource_metadata URL rather than resource identifier

It was decided to start working group last call during the OAuth meeting.

6: COSE “typ” (type) Header Parameter. Updates were:

  • Added language about media type parameters
  • Addressed working group last call comments
  • Changed requested assignment from 14 to 16 due to conflict with a new assignment
  • Addressed GENART, OPSDIR, and SECDIR review comments

This document is scheduled for the April 4, 2024 IESG telechat.

7: Barreto-Lynn-Scott Elliptic Curve Key Representations for JOSE and COSE. Updates were:

  • Changed to use key type EC for JOSE and equivalent EC2 for COSE for uncompressed key representations
  • Changed identifier spellings from “Bls” to “BLS”, since these letters are people’s initials

We received feedback to not add compressed key representations to the draft.

8: Use of Hybrid Public-Key Encryption (HPKE) with JavaScript Object Signing and Encryption (JOSE). Updates were:

It was decided to start a working group call for adoption during the JOSE meeting.

Thanks to all who contributed to the progress made on these specifications, both before and during IETF 119!

Celebrating Ten Years of OpenID Connect at the OpenID Summit Tokyo 2024

In Claims, Events, Federation, History, JSON, OAuth, OpenID, Specifications

OpenID logoWe held the first of three planned tenth anniversary celebrations for the completion of OpenID Connect at the OpenID Summit Tokyo 2024. The four panelists were Nov Matake, Ryo Ito, Nat Sakimura, and myself. We shared our perspectives on what led to OpenID Connect, why it succeeded, and what lessons we learned along the way.

The most common refrain throughout our descriptions was the design philosophy to “Keep simple things simple”. I believe that three of the four of us cited it.

I recounted that we even had a thought experiment used to make the “Keep simple things simple” principle actionable in real time: the “Nov Matake Test”. As we considered new features, we’d ask ourselves “Would Nov want to add it to his implementation?” And “Is it simple enough that he could build it in a few hours?”

The other common thread was the criticality of interop testing and certification. We held five rounds of interop testing before finishing the specifications, with the specs being refined after each round based on the feedback received. The early developer feedback was priceless – much of it from Japan!

Our OpenID Connect 10th anniversary presentations were:

OpenID logoI’m pleased to bring your attention to the upcoming OpenID Summit Tokyo 2024, which will be held on Friday, January 19, 2024. Join us there for a stellar line-up of speakers and consequential conversations!

OpenID Summit Tokyo 2024

This builds on the successes of past summits organized by the OpenID Foundation Japan. For instance, I found the OpenID Summit Tokyo 2020 and associated activities and discussions both very useful and very enjoyable.

A special feature of the 2024 summit will be celebrating the 10th anniversary of the OpenID Connect specifications, which were approved on February 25, 2014. Speakers who were there for its creation, interop testing, and early deployments will share their experiences and lessons learned, including several key participants from Japan. As I recounted at EIC 2023, building ecosystems is hard. And yet we achieved that for OpenID Connect! We are working to create new identity ecosystems as we speak. I believe that the lessons learned from OpenID Connect are very applicable today. Come join the conversation!

Finally, as a teaser, I’m also helping the OpenID Foundation to plan two additional 10th anniversary celebrations at prominent 2024 identity events – one in Europe and one in the Americas. Watch this space for further news about these as it develops!

What does Presentation Exchange do and what parts of it do we actually need? (redux)

By

In Events, Specifications

IIW LogoI convened the session “What does Presentation Exchange do and what parts of it do we actually need?” this week at the Internet Identity Workshop (IIW) to continue the discussion started during two unconference sessions at the 2023 OAuth Security Workshop. I briefly summarized the discussions that occurred at OSW, then we had a vigorous discussion of our own.

Key points made were:

  • There appeared to be rough consensus in the room that Presentation Exchange (PE) is pretty complicated. People had differing opinions on whether the complexity is worth it.
  • A lot of the complexity of PE comes from being able to request multiple credentials at once and to express alternatives.
  • Ultimately, the verifier knows what kinds of credentials it needs and the relationships between them. PE tries to let the verifier express some of that to the wallet.
  • Code running in the verifier making choices about the credentials it needs will always be more powerful than PE, because it has the full decision-making facilities of programming languages – including loops, conditionals, etc.
  • Making a composite request for multiple credentials can have a better UX than a sequence of requests. In some situations, the sequence could result in the person having to scan multiple QR codes. There may be ways to avoid that, while still having a sequence of requests.
  • Some said that they need the ability to request multiple credentials at once.
  • Brent Zundel (a PE author) suggested that while wallets could implement all of PE, verifiers could implement only the parts they need.
  • Not many parties had implemented all of PE. Torsten Lodderstedt suggested that we need feedback from developers.
  • We could create a profile of PE, reducing what implementers have to build and correspondingly reducing its expressive power.

The slides used to summarize the preceding discussions are available as PowerPoint and PDF. There are detailed notes capturing some of the back-and-forth at IIW with attribution.

Thanks to everyone who participated for an informative and useful discussion. My goal was to help inform the profiling and deployment choices ahead of us.

P.S. Since Thursday’s discussion, it occurred to me that a question I wish I’d asked is:

  • When a verifier needs multiple credentials, they may be in different wallets. If the verifier tries to make a PE request for multiple credentials that are spread between wallets, will it always fail because no single wallet can satisfy it?

Fodder for the next discussion…

EIC 2023 LogoI was surprised and deeply honored to receive a Lifetime Achievement Award from Kuppinger Cole at EIC 2023. As I recalled when accepting the award, when Kim Cameron received the same award about a decade ago, he said from the podium “No, don’t do this! My career isn’t over! I’m not done contributing!” Kim always had a wicked wit. ;-)

Coincidentally, I described some of the achievements that led to the award during my keynote Touchstones Along My Identity Journey. After a couple of times of me saying “We won an award for that” during the keynote, I was amused that the audience would break out into laughter each subsequent time that I mentioned another award. Like this award, the audience’s reaction was unexpected and delightful.

EIC 2023 LogoI had the distinct honor of being invited to give a keynote talk at EIC 2023. The result was Touchstones Along My Identity Journey. My talk abstract was:

In 2005, Kim Cameron excitedly told me about digital identity and set my life on a course to “Build the Internet’s missing identity layer”. In this talk I’ll tell key stories from my identity journey — stories of the people, ideas, and lessons learned along the way. I’ll speak of technology and collaboration, usability and business models, solving problems people actually have, and building new ecosystems. Come with me on this journey of exploration, trials, triumphs, and humor as I recount touchstones of the human endeavor that is digital identity.

Kuppinger Cole has posted a video of my keynote on YouTube. I was pleased with how well it went. After the first few sentences, I was in the zone! I hope many of you find the messages in the talk useful.

My slides are also available in (PowerPoint) and PDF.

Special thanks go to the OpenID Foundation for supporting my trip to EIC this year and to designer Alistair Kincaid at MATTR for helping me transcend my usual black-bulleted-text-on-a-white-background presentation style!

EIC 2023 LogoThe session Current Work and Future Trends in Selective Disclosure at EIC 2023 covered a lot of foundational work happening in the space of Selective Disclosure right now. Selective Disclosure enables you to have a token with many claims (say, an ISO Mobile Drivers’ License (mDL)), and only release the claims necessary for the interaction — for instance, your birthdate but not your home address. Selective Disclosure enables Minimal Disclosure. This is sometimes realized using Zero Knowledge Proofs (ZKPs) but that’s not always necessary.

How do you know who to trust?

In Events, Federation, OpenID, People

EIC 2023 LogoGiuseppe De Marco and I presented the session How do you know who to trust? at EIC 2023.

A key question when granting access to resources is ‘Who do you trust?’. It’s often important to know who the party is that you’re interacting with and whether they’ve agreed to the terms and conditions that apply when accessing a resource.

OpenID Connect enables identities of participants to be securely established but doesn’t answer the question of whether a participant is trusted to access a resource such as your personal data. A complementary mechanism is needed to do that. In small-scale and static deployments, it’s possible to keep a list of the trusted participants. However, in large-scale and dynamic deployments, that doesn’t scale.

This presentation described how the OpenID Connect Federation protocol enables scalable trust establishment with dynamic policies. It does so by employing trust hierarchies of authorities, each of which are independently administered. Examples of authorities are federation operators, organizations, departments within organizations, and individual sites.

Two OpenID Connect Federations are deployed in Italy, enabling secure access to digital services operated by Italian public and private services with Italian digital identities. This presentation described why OpenID Connect Federation was selected for them and how it meets their needs. OpenID Connect Federation is also being used by the GAIN PoC.

Our presentation is available in (PowerPoint) and PDF.
