Explore the scalable cloud trust attestation management system Keylime in this 38-minute conference talk by Andrew Toth from Red Hat. Learn about bootstrapping hardware-rooted cryptographic identities for IaaS nodes and system integrity monitoring through periodic attestation using Trusted Platform Module (TPM) technology. Discover the origins of Keylime at MIT's Lincoln Laboratory and its evolution into an open-source community focused on securing untrusted remote infrastructures. Gain insights into the what, why, and how of Keylime and TPM, followed by a practical demonstration. The talk covers key topics including cloud nodes, essential definitions, Keylime setup, tasks, and virtual TPM, concluding with a Q&A session.
