Explore the evolution of Keylime, a TPM-based remote attestation framework, in this 37-minute conference talk from DevConf.CZ 2025. Discover how the framework transitioned from a traditional pull-based model to an innovative push-based (agent-driven) attestation approach to better serve edge and IoT environments. Learn about the architectural changes implemented to address the challenges faced by resource-constrained devices operating behind firewalls, where the original verifier-initiated attestation requests proved problematic. Examine the technical hurdles overcome during this transformation and understand how the new agent-driven model, where monitored systems actively push integrity measurements to verifiers, makes remote attestation more practical for edge, cloud, and IoT deployments. Gain insights into the open-source collaboration that enabled these advancements and see how community-driven development addresses real-world security challenges in modern distributed computing environments.
