In our ongoing series on digital identity for agents, we have previous discussed use of certificates for authentication. In this episode we describe how cryptographic proof of possession can enable secure authentication using tokens.
We survey different strategies for securely authenticating agentic AI, including certificates and SPIFFE. We discuss Zero Trust and the Principle of Least Privileges as applied to agents.
Anthropic has announced its intentions to support SPIFFE/SPIRE with the SPIRE server rooted in an "upstream authority," which will require a root private CA rather than allowing self-attestation for agentic AI.
In our episode 640 we defined SPIFFE, which provides digital identity for agentic workloads. In this episode we explain SPIRE (SPIFFE Runtime Environment), the SPIFFE certificate provisioning protocol.
SPIFFE (Secure Production Identity Framework for Everyone) is a standard for digital identity for agentic workloads. In this episode we explain.
Static API keys are a common security practice. In this episode we discuss the risk of these keys being revealed, including directly by the AIs that use them.
Tim shares his very personal experience with would-be catfishers and we talk about how AI is set to change the catfishing attack.
The Baseline Requirements, CT logs, the Bugzilla Bloodbath, shortening certificate lifespans, all these trends serve to enforce a high level of quality and predictability across WebPKI certificates. Nearly twenty years after the introduction of EV SSL, we ask if it has served its purpose and should be retired.
Dustin Moody of NIST joins us to talk about the evolution of standardized cryptography beyond the current PQC efforts. Topics include maintaining visibility on cryptography presently in use, 50 years of RSA, and cryptographic heterogeny.
Bas Westerbaan of Cloudflare joins us to discuss recent information that heightens concerns about Elliptic Curve Cryptography (ECC) and its vulnerability to a cryptographically relevant quantum computer (CRQC). We pose the question do we need to deprecate ECC in advance of our migration to ML-DSA and other PQC algorithms.
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.
