The BIOS is also adapted to receive TPM authentication data from the user for initiating a boot process and interface with the TPM to request validation of the TPM authentication data by the TPM for initiating the boot process using the user key.
BACKGROUND Computer systems generally function under the control or execution of an operating system (OS). Operating systems require a loading (i.e., �boot�) process to load the OS into a computer memory. The boot process generally includes locating a basic input/output system (BIOS), loading the BIOS for execution, and passing control of the computer system to the BIOS. Thereafter, the BIOS loads the OS.
SUMMARY OF THE INVENTION In accordance with one embodiment of the present invention, a computer security system comprises a basic input/output system (BIOS) adapted to store a user key generated by a trusted platform module (TPM) for a user. The BIOS is also adapted to receive TPM authentication data from the user for initiating a boot process and interface with the TPM to request validation of the TPM authentication data by the TPM for initiating the boot process using the user key.
