  • Thank you so much

    Been in the systems engineering space for 10 years and I’ve continued to struggle with PKI and CA. The concept I get sure but execution in the organizations I’ve been apart of always looked like some disgusting, unscalable sidecar process that we all just had to do. This podcast has slowly filled those gaps in helping me understand soup to nuts what it’s all about, the risks, and what right looks like. Thanks guys! Love the show.

Talking Points

Recent interactions between the hosts and their guests.

Root Causes 618: MTC and Private PKI
Q: What are the practical downsides of Merkle Tree Certificates for private PKI, and when might they not be worth it?
Size and landmark management are core concerns; for some operators with small, light-weight devices or limited trusted channels, sticking with traditional approaches might be simpler unless the benefits of reduced signing operations or improved downgrades handling justify the complexity.
Root Causes 618: MTC and Private PKI
Q: If I enforce 100% PQC compliance and require that non-PQC entities can't connect, is MTC really necessary?
You can deploy plain PQC as is, but many environments benefit from MTC when there are large signature workloads or when you need the efficiency of signing a tree head that represents many certificates at once.
Root Causes 613: Status of the NIST PQC Contests
Q: What are the main criteria used to evaluate PQC algorithms?
Security against classical and quantum attacks, potential for a formal security proof, performance metrics (key sizes, ciphertext/signature sizes, speed), and implementation characteristics including side-channel resistance and IP concerns.
Root Causes 613: Status of the NIST PQC Contests
Q: What is the purpose of having multiple algorithms beyond lattice-based ones?
To ensure cryptographic diversity and resilience, reducing reliance on a single mathematical approach, and to prepare for potential future cryptanalytic breakthroughs or attacks on lattices.
Root Causes 613: Status of the NIST PQC Contests
Q: Where are we with Falcon and HQC in terms of standards and publication?
Falcon will be included in FIPS 207 as FNDSA after completing its internal testing and receiving chain-of-approval; HQC is in the works for a September-ish draft with public comments to follow, as a backup non-lattice chem.
