I don't think so.
Yes. It would be different. In the absence of a TPM chip, the system can be constructed in such a way that disk forensics (or more simply: examination of the installation CD) is required. In the *presence* of a TPM chip, inspection can be prohibited. In practice, inspection of the code and initial data probably isn't a critical issue, and I think that allowing it in general poses no great difficulties. The complicated issue is inspection of runtime state, which definitely *can* be prevented in a constructor system, with or without the TPM chip. All of this assumes no bus probes. shap _______________________________________________ L4-hurd mailing list [email protected] http://lists.gnu.org/mailman/listinfo/l4-hurd
