A new kind of eIDAS QWAC (Qualifieid Website Authentication Certificate) is on the way. The "two-QWAC architecture" introduces a second certificate containing organization information to be displayed by the browser, to sit alongside but independent of the certificate that authenticates a domain. We explain what's coming and why.
An environment in which credentials are extremely predictable could be described as an entropy desert. There are occurring at a global scale. We discuss concepts like measurable entropy availability and entropy by design.
In this episode we build on our concept of entropy-aware guidance to explain how we might quantify privacy. We touch on GDPR, proof of work, and Landaur's principle.
A patent dispute in 2024 nearly blocked ML-KEM. But emerging thinking raises concern that the 2024 resolution did not guarantee full, clear access to all ML-KEM implementations. We explain.
The CPS must always be a superset of actual practices in a properly running CA. We explain why this is a product of good design.
Imagine what happens if you use the wrong LLM, including a malicious model placed there to create mischief or crime. How do you know? Jason proposes that, the same way we sign our code, we should be signing our AI models as well.
We discuss how a static PKI structure can hurt corporate flexibility and resilience. Events like reorgs and M&A activity can cause intractable problems with the wrong PKI setup. Plus, Jason coins the term PKI archeology.
In this episode, Jason describes how we might use the principles of PKI in a purely offline scenario.
Public certificates are transitioning from multi-purpose root hierarchies to single-purpose ones. We discuss why.
We compare AI in 2025 to Internet in 1995 and describe the AI iceberg, including the majority of applications which are below the waterline.
Verified Mark Certificates (VMC) now have a companion product for logos that are not registered trademarks, called a Common Mark Certificate (CMC). We explain the differences.
A CA has incorrectly issued TLS certificates for the 1.1.1.1 and 2.2.2.2 IP addresses. We go into the details.
Client authentication using public TLS server certificates is on the deprecation path. In this episode we go through the key dates in this deprecation.
Based on the ready availability of AI-based voice cloning, we declare voice biometric authentication to be utterly valueless.
A new CABF ballot proposal will eliminate all email- and phone-based DCV over the next few years. We go into the details.
Three major changes are coming to the world of public certificates, all of which require major changes in how organizations deploy, renew, and manage their certificates. These are 47-day SSL, PQC, and the deprecation of mTLS. We describe the overlap between these efforts and how to combine them for better efficiency and project management.
MPIC (Multi-perspective Issuance Corroboration) is soon to move into enforcement phase. In this episode we describe three configuration decisions that can force Domain Control Validation (DCV) to fail and tell you what to do about them before you have a problem.
We complete our description and commentary on the results of Sectigo's survey of enterprise preparedness for Post Quantum Cryptography (PQC).
We begin to go over the results of Sectigo's recent survey of enterprises and their preparedness and plans for adopting Post Quantum Cryptography (PQC).
Sectigo has released the results of its survey of IT professionals in charge of certificates to measure their readiness and preparation for 47-day maximum certificate term. We go over the results.
