Louis Ferraro Security Architect - AMD, Miguel Osorio Senior Staff Software Engineer - Google, Ravi Sahita PMTS - Rivos This presentation highlights significant strides made in the OpenPRoT initiative, emphasizing advancements in architecture specification and code development since its introduction. As an open-source-open-standard Platform Root of Trust firmware stack, a central theme of our progress is the reusability of components, ensuring modularity and interoperability across various platforms, thus accelerating industry adoption while lowering costs. Furthermore, we will explore collaborative efforts with other OCP projects, notably code sharing, reuse, and interoperability with Caliptra, which underscores a unified approach in security standards. This collaboration enhances both projects capabilities, fostering innovation and cohesion within the OCP community. We also cover how OpenPRoT can be used to reduce the complexity of attestation flows by providing standard interfaces, using OpenTitan hardware as an example. Join us to learn how OpenPRoT continues to drive transparency, security, and collaboration in the computing ecosystem.
An Update on OpenTitan
Genode - Genode Operating System Framework
We understand the complexity of code and policy as the most fundamental security problem shared by modern general-purpose operating systems. Because of high functional demands and dynamic workloads, however, this complexity cannot be avoided. But it can be organized. Genode is a novel OS architecture that is able to master complexity by applying a strict organizational structure to all software components including device drivers, system services, and applications. The Genode OS framework is an open-source tool kit for building highly secure component-based operating systems. It scales from embedded devices to dynamic general-purpose computing.

NSF investing in secure open-source ecosystems
Open-source software is ubiquitous, supporting artificial intelligence, data science, cloud computing, telecommunications and scientific research tools. Despite these benefits, the number of open-source developers is relatively small, and many projects lack sufficient resources, slowing the pace of innovation and making maintenance difficult. In addition, weaknesses in open-source software, such as security flaws, supply chain risks or insider threats, can spread across many connected systems. In extreme cases, these weaknesses could lead to large-scale failures that affect national or global systems.
