TwPM

The Trusted Platform Module or TPM is a dedicated hardware component designed for providing additional security features for computing platforms. 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.

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.

The main goal of the project is an attempt to create open-source firmware stack, implementing the TCG PC Client Platform TPM Profile specification. Project aims to use already available open-source software components whenever possible (such as TPM simulators for TPM commands handling), while developing new code when necessary (such as LPC FPGA module, or low-level TPM FIFO interface handling). Another challenge is to overcome hardware restrictions and allow users to use the open-source TPM implementation on generally-accessible development boards.
