As embedded systems become increasingly interconnected, the demand for robust platform security and integrity has surged. Trusted Platform Modules (TPM), currently in version 2.0, are becoming increasingly beneficial for enhancing security in embedded systems. TPMs provide hardware-backed mechanisms for critical functions such as random number generation, cryptographic key generation, key binding and data sealing.
This presentation will explore the capabilities of TPM 2.0, focusing on several practical use cases, including:
- Providing a unique and persistent serial number for device identification.
- Supporting secure boot mechanisms to establish a reliable chain of trust.
- Encrypting user data without the need for user passwords.
- Managing application credentials securely.
Additionally, we will discuss the integration of TPM 2.0 within Yocto-based embedded systems and present strategies for automated provisioning, highlighting how these elements work together to enhance overall system security.

In our community, building embedded systems based on Linux, e.g. with Yocto or buildroot, is standard and well known. Considering Android, respectively the AOSP as a base system feels strange at the beginning as it is a huge ecosystem that implies high system requirements. Of course, embedded Android is not a solution for each issue. Nevertheless, the AOSP provides a sophisticated base platform which is packed with a

Using KAS makes handling Yocto Projects easy. By shipping its own container with all needed dependencies, building sophisticated CI pipelines becomes pretty easy - in theory, or when using Gitlab.
But using GitHub as a code hosting platform with self-managed Action runners on AWS comes with a set of unexpected challenges.
Anna-Lena will talk about her quest through GitHub Actions, the Cloud and how to tame them.
The talk aims to point the audience to the obstacles when building CI pipelines for the Yocto Project with KAS, GitHub Actions, and custom action runners on AWS and strategies to handle them.
