Keep these keys secure, ideally there would be a password on them and maybe they'd be stored in HSM Hardware Security Module , but for now, this is suitable for a development platform. Its another "magic number" that may require some guessing. More magic numbers. Defining it is optional but helpful. It is required. Once done, the policy needs to be written to the TPM. If using signed lists, this only needs to be done once unless the key is changed.

Figure 2 — Static Root Trust of Measurement SRTM produces excellent results and a great level of security -- mainly against offline attacks --but the problem is that multiple components must be verified in the chain of trust once TPM is initialized.
