|---|---|---|---|---|---|---|---|---|---|
| 6/24/26 |  Root Causes 633: ETSI PQC Conference Wrap Up | We are freshly returned from the 2026 ETSI PQC Conference. We give a debrief on the conference, including the difference between post quantum cryptography (PQC) and quantum key distribution (QKD), the algorithmic zoo, PQC for blockchain, the Dunning Kruger Effect, and cryptographic Frogger. | — | ||||||
| 6/22/26 |  Root Causes 632: Gartner Risk and Security 2026 Wrap Up | We recently attended the Gartner Risk and Security conference for 2026, where we observed a great deal of attention on not only AI but also post quantum cryptography (PQC). Join us as we share the key takeaways. | — | ||||||
| 6/19/26 |  Root Causes 631: Did the Bugzilla Bloodbath Change Anything? | 2024 saw a flurry of high profile incidents for public CA, which we named the Bugzilla Bloodbath. We look back to see how the WebPKI has changed as a consequence. | — | ||||||
| 6/17/26 |  Root Causes 630: The PQC Physicality Crisis | Resource-constrained devices may need to address PQC through real-time, seed-based, key generation. Unfortunately, this leaves the full key exposed very briefly in RAM. The potential consequences of this are far-reaching and scary. We go into the details. | — | ||||||
| 6/15/26 |  Root Causes 629: Does the Evidence Support Moving PQC Deadlines to 2029? | Sam Jaques of the University of Waterloo returns to discuss his tracking of progress in quantum computers and offer a perspective on moving our PQC deadlines up to 2029. | — | ||||||
| 6/12/26 |  Root Causes 628: PI-DOS (Prompt Injection-based Denial of Service) | An emerging attack against AIs is to create a significantly complex and recursive prompt that will occupy the AI indefinitely or for a sufficiently long time that it acts as a Denial-of-Service (DoS) attack. We describe how this works. | — | ||||||
| 6/10/26 |  Root Causes 627: UK vs Apple E2EE Backups | In the latest in our coverage of government versus encryption, the UK issued secret orders to Apple to give it a cryptographic backdoor to Apple's advanced data protection capability for iCloud. Apple responded by eliminating encryption entirely for UK users. We break it down. | — | ||||||
| 6/8/26 |  Root Causes 626: TLS 1.3 Roadblock | TLS 1.3 is required to take advantage of post quantum cryptography (PQC) algorithms. Yes, we still see a lot of TLS 1.2 or earlier in deployment. We examine why this is the case and what to do about it. | — | ||||||
| 6/5/26 |  Root Causes 625: AI in 1000 Days - Cyber Defense | Recent revelations about Mythos and its ability to expose vulnerabilities have forced us to rethink basic assumptions about cyber defense. In our "AI in 1000 Days" series, Jason Soroko and I examine the implications of these revelations three years from now. This includes upping the overall pace of attack and changes to best practices in cyber security defense. | — | ||||||
| 6/3/26 |  Root Causes 624: Implications of Mythos | Anthropic has delayed its widespread release of Mythos to give major software providers a chance to close off the many vulnerabilities it has discovered. We dig into the vast implications of Mythos and other AI models for the future of cybersecurity. | — | ||||||

| 6/1/26 |  Root Causes 623: Are PQC Key Sized Big Enough? | We discuss the possibility that our standardized ML-DSA keys turn out to be too short for true confidence, why that might occur, and the implications for private PKI certificates. | — | ||||||
| 5/29/26 |  Root Causes 622: Modeling the Time to CRQC | Sam Jaques joins us to explain his much-referenced chart mapping progress toward cryptographically relevant quantum computing (CRQC). | — | ||||||
| 5/26/26 |  Root Causes 621: Simplicity at Scale | We break down the phrase "Simplicity at Scale" to see what it means to us in the context of CAs and CLM. | — | ||||||
| 5/22/26 |  Root Causes 620: Will NIST Update Its PQC Timelines? | A few years ago NIST proposed deadlines for PQC deployment at 2030 and 2035. But recent announcements from Google and Cloudflare suggest 2029 as a better deprecation target. We are joined by Dustin Moody to get the NIST perspective on these announcements. | — | ||||||
| 5/18/26 |  Root Causes 619: Do We All Need to Adopt PQC by 2029? | Recent announcements from Google and Cloudflare have declared new 2029 deadlines for full post quantum cryptography (PQC) migration. Bas Westerbaan explains the rationale behind Cloudflare's decision and discusses implications for other enterprises, asking "Are you a gambler?" | — | ||||||
| 5/15/26 |  Root Causes 618: MTC and Private PKI | Repeat guest Bas Westerbaan of Cloudflare joins us to explore the role of Merkle Tree Certificates in private CA scenarios with an eye toward where they will be needed and where traditional PKI will be better suited. | — | ||||||
| 5/13/26 |  Root Causes 617: What Are X9 Certificates? | The US-based X9 financial industry consortium has created a server certificate. We explain what X9 certificates are and suitable use cases for this certificate type. | — | ||||||
| 5/11/26 |  Root Causes 616: NIST and Merkle Tree Certificates | Dustin Moody of NIST joins us to discuss Merkle Tree Certificates (MTC) and the NIST position on them. | — | ||||||
| 5/8/26 |  Root Causes 615: What Is IETF PLANTS? | Repeat guest Bas Westerbaan of Cloudflare joins us to explain the PLANTS working group in IETF, which is driving standards around post quantum cryptography (PQC) and Merkle Tree Certificates (MTC). Bas explains the path to becoming a final standard, where we are in this process, and how you can get involved. | — | ||||||
| 5/6/26 |  Root Causes 614: MTC and Downgrade Attacks | It's reasonable to believe that Merkle Tree Certificates (MTC) and traditional RSA will co-exist on the same servers for years, if not decades, during the transition to post quantum cryptography (PQC). Bas Westerbaan of Cloudflare joins us in this episode to explore the possibility of quantum downgrade attacks and what we can do about them. | — | ||||||
| 5/4/26 |  Root Causes 613: Status of the NIST PQC Contests | We are joined by Dustin Moody of NIST to go over the current state of the various post quantum cryptography (PQC) contests, including upcoming FIPS standards for Falcon (FN-DSA) and HQC, other Round 4 algorithms, the digital signing algorithm (DSA) On Ramp, isogeny, and future cryptographic exploration. | — | ||||||
| 5/1/26 |  Root Causes 612: What Do Subscribers Need for MTC? | We are joined by Bas Westerbaan of Cloudflare to explain considerations and requirements for use of Merkle Tree Certificates (MTC). This includes full adoption of TLS 1.3, offering PQC and RSA at the same time, the imperative value of automation, and running production MTC in 2027. | — | ||||||
| 4/29/26 |  Root Causes 611: Merkle Tree Certificates, What and Why | There are strong reasons to believe that the architecture of PQC TLS will take the form of Merkle Tree Certificates (MTC). We are joined by post quantum cryptography expert Bas Westerbaan of Cloudflare as he explains this new PKI architecture, how it works, and why we need it. We define new concepts like landmark certificates and log mirrors and discuss what's necessary to move to this new architecture. | — | ||||||
| 4/27/26 |  Root Causes 610: Types of Logical Qubits | We describe three different kinds of logical qubits with their relative strengths and weaknesses. | — | ||||||
| 4/24/26 |  Root Causes 609: Side Channel Apocalypse | Jason explains the extreme danger of side channel attacks in the new post quantum cryptography (PQC) era. | — | ||||||
