Windows Insight: The TPM

The Windows Insight repository currently hosts three articles on the TPM (Trusted Platform Module):

  • The TPM: Communication Interfaces (Aleksandar Milenkoski): In this work, we discuss how the different components of the Windows 10 operating system deployed in user-land and in kernel-land, use the TPM. We focus on the communication interfaces between Windows 10 and the TPM. In addition, we discuss the construction of TPM usage profiles, that is, information on system entities communicating with the TPM as well as on communication patterns and frequencies;
  • The TPM: Integrity Measurement (Aleksandar Milenkoski): In this work, we discuss the integrity measurement mechanism of Windows 10 and the role that the TPM plays
    as part of it. This mechanism, among other things, implements the production of measurement data. This involves calculation of hashes of relevant executable files or of code sequences at every system startup. It also involves the storage of these hashes and relevant related data in log files for later analysis;

  • The TPM: Workflow of the Manual and Automatic TPM Provisioning Processes (Aleksandar Milenkoski): In this work, we describe the implementation of the TPM provisioning process in Windows 10. We first define the term TPM provisioning in order to set the scope of this work. Under TPM provisioning, we understand activities storing data in the TPM device, where the stored data is a requirement for the device to be used. This includes: authorization values, the Endorsement Key (EK), and the Storage Root Key (SRK).
