    Abstract: The method involves loading a component of an operating system into a specific region (275) of a memory by the active one of the CPUs (210,220,230) of a multi-processor system (200). The identity of the loaded component is registered. The active CPU is made to jump to a known entry point in the specific region. Independent claims are also included for the following: (1) article of manufacture comprising computer readable medium storing operating system loading program; (2) method of securing a region in computer memory; and (3) apparatus to load trustable operating system.

    Abstract: A method and apparatus for initiating secure operations in a microprocessor system is described. In one embodiment, one initiating logical processor initiates the process by halting the execution of the other logical processors, and then loading initialization and secure virtual machine monitor software into memory. The initiating processor then loads the initialization software into secure memory for authentication and execution. The initialization software then authenticates and registers the secure virtual machine monitor software prior to secure system operations.

    Abstract: A method and apparatus for resetting and modifying special registers in a security token is described. In one embodiment, a register may be reset when a reset flag is true when a special transmission on a bus demonstrates the mutual locality of the associated processor and chipset. A modify flag may also be used to indicate whether the register contents may be modified. Modifications may also be dependent upon demonstration of mutual locality.

    Abstract: Delivering a Direct Proof private key in a signed group of keys to a device installed in a client computer system in the field may he accomplished in a secure manner without requiring significant non-volatile storage in the device. A unique pseudo-random value is generated and stored along with a group number in the device at manufacturing time. The pseudo-random value is used to generate a symmetric key for encrypting a data structure holding a Direct Proof private key and a private key digest associated with the device. The resulting encrypted data structure is stored in a signed group of keys (e.g., a signed group record) on a removable storage medium (such as a CD or DVD), and distributed to the owner of the client computer system. When the device is initialized on the client computer system, the system checks if a localized encrypted data structure is present in the system. If not, the system obtains the associated signed group record of encrypted data structures from the removable storage medium, and verifies the signed group record. The device decrypts the encrypted data structure using a symmetric key regenerated from its stored pseudo-random value to obtain the Direct Proof private key, when the group record is valid. If the private key is valid, it may be used for subsequent authentication processing by the device in the client computer system.

    Abstract: A method and apparatus is provided in which a trustable operating system is loaded into a region in memory. A start secure operation (SSO) triggers a join secure operation (JSO) to halt all but one central processing unit (CPU) in a multi-processor computer. The SSO causes the active CPU to load a component of an operating system into a specified region in memory, register the identity of the loaded operating system by recording a cryptographic hash of the contents of the specified region in memory, begin executing at a known entry point in the specified region and trigger the JSO to cause the halted CPUs to do the same.
