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)…
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. …
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…
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…
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…
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.
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).
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.
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…
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…
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…
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.
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.
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).…
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…
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…
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…
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…
Root Causes 610: Types of Logical Qubits
We describe three different kinds of logical qubits with their relative strengths and weaknesses.
Root Causes 609: Side Channel Apocalypse
Jason explains the extreme danger of side channel attacks in the new post quantum cryptography (PQC) era.
