    摘要: If a user forgets the power-on password of his computer, he can depress the “enter” key or “access” key once to cause the BIOS to locate the power-on password in memory and attempt to unlock the HDD using the power-on password to boot a secure O.S. The HDD password either can be the same as the power-on password or the HDD can recognize the power-on password for the limited purpose of allowing access to the secure O.S. In any case, the secure O.S. is booted for password reset.

    摘要: A system, method, and program product is provided that executes a start sequence of an information handling system that includes a hardware based TPM. Multiple PCRs are stored in the TPM and are initialized to a predetermined state when the start sequence commences. During execution of the start sequence, software modules, including a hypervisor, are loaded the system's memory. PCR values resulting from the loading of the software modules are calculated. The resulting PCR values are compared with expected PCR values. If the PCR values match the expected PCR values, then a virtual environment is created under the hypervisor. The virtual environment includes a VM and a virtual trust platform module (vTPM) that is used by the virtual machine to satisfy the virtual machines TPM requests.

    摘要: An apparatus, system, and method are disclosed for protecting hard disk data in multiple operating system environments. The present invention restricts access of a hard file to a range of logical addresses using a controller module configured to access a hard file in response to a request for a logical address, a set zero module configured to add an offset value to each request for a logical address on a hard file, and a set max module configured to set a maximum logical address accessible on a hard file. The invention limits access to a lower protected area with logical addresses below the range of logical address and a host protected area with logical address above the range of logical addresses.
