Orie Steele and I want to thank Deb Cooley for her Area Director review of the “Fully-Specified Algorithms for JOSE and COSE” specification. Addressing it simplified the exposition, while preserving the essence of what the draft accomplishes. Specifically, the resulting draft significantly simplified the fully-specified encryption description and removed the appendix on polymorphic ECDH algorithms. […]

Emil Lundberg and I have published the COSE Algorithms for Two-Party Signing specification. Its abstract is: This specification defines COSE algorithm identifiers used when the signing operation is performed cooperatively between two parties. When performing two-party signing, the first party typically hashes the data to be signed and the second party signs the hashed data […]

Vladimir Dzhuvinov and I led a discussion on The Cambrian Explosion of OAuth and OpenID Specifications at the 2025 OAuth Security Workshop in Reykjavík. The abstract for the session was: The number of OAuth and OpenID specifications continues to grow. At present there are 30 OAuth RFCs, two more in the RFC Editor queue, 13 […]

The W3C Verifiable Credentials Working Group has published a Snapshot Candidate Recommendation of the Controlled Identifiers specification. This follows the five Candidate Recommendation Snapshots published by the working group in December 2024. Two of these specifications, including Securing Verifiable Credentials using JOSE and COSE, depend upon the Controlled Identifiers spec. The planned update to the […]

Kim Cameron first told me what Digital Identity is on February 1, 2005. He said that the Internet was created without an identity layer. He encouraged me “You should come help build it with me.” I’ve been at it ever since! What I wrote about digital identity a decade ago remains as true today: An […]

The W3C Verifiable Credentials Working Group published the Snapshot Second Candidate Recommendation of the Securing Verifiable Credentials using JOSE and COSE specification just before the holidays. This was one of five Candidate Recommendation Snapshots published by the working group at the same time, including for the Verifiable Credentials Data Model 2.0, which I’m also an […]

I’m writing to highly recommend the article “How to link an application protocol to an OpenID Federation 1.0 trust layer” by Vladimir Dzhuvinov. In it, he defines two kinds of integrity for Federations, and describes how to achieve them: Federation Integrity, which is defined as: This ensures mutual trust between two entities is established always […]

The OpenID Connect working group recently adopted three new specifications that build upon and provide new capabilities to OpenID Federation. But I’m not only happy about these because of the engineering benefits they bring. I’m particularly happy because they bring new active contributors to the work, specifically Michael Fraser and Łukasz Jaromin, as well as […]
