TwPM project aims to increase the trustworthiness of the TPM module (hence the TwPM), by providing the open-source firmware implementation for the TPM device, compliant to the TCG PC Client Specification. Trusted Platform Modules (TPM) enable measured boot and support verified boot, Dynamic Root of Trust for Measurement, and other security features. Currently, the market is dominated by the TPMs based on chips from large silicon vendors. The common characteristic of these modules is the proprietary firmware implementation. This presentation will outline the project's goals, design, current challenges, and status. The goal is also to gather a community around this project and exchange ideas on the subject.
