Abstract:
PROBLEM TO BE SOLVED: To provide an effective method and a device for validating whether a platform is included in a data center. SOLUTION: A machine-readable storage medium providing instructions to make a machine perform processing when executed by the machine carries out steps of: revoking a current cryptographic key pair held in the optional number of servers in a data center computer system when it is determined that one of the optional number of servers in the data center computer system is damaged; generating a new cryptographic key pair associated with the data center computer system; and storing a new private key of the new cryptographic key pair in the optional number of damaged servers.

Abstract:
PROBLEM TO BE SOLVED: To disclose a system and a method for allowing execution of a system management mode (SMM) code during secure operations in a microprocessor system.SOLUTION: In one embodiment, a system management interruption (SMI) can be first directed to a handler in a secured virtual machine monitor (SVMM). Then, the SMI can be redirected to a SMM code located in a virtual machine (VM) which is under the security control of the SVMM. This redirection can be achieved by enabling reading from and writing onto the system management (SM) base register in the processor.

SOLUTION: In one embodiment, a system management interruption (SMI) may be first directed to a handler in a secured virtual machine monitor (SVMM). The SMI may then be re-directed to an SMM code located in a virtual machine (VM) that is under the security control of the SVMM. This redirection can be accomplished by allowing reading from and writing to the system management (SM) base register in the processor. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method for executing a secured environment initialization instruction.SOLUTION: A method and an apparatus for initiating secure operations in a microprocessor system are described. In one embodiment, one initiating logical processor initiates a process by halting execution of the other logical processors and by loading initialization software and secure virtual machine monitor software into a memory. The initiating processor loads the initialization software into a secure memory for authentication and execution. The initialization software authenticates and registers the secure virtual machine monitor software prior to secure system operations.

PROBLEM TO BE SOLVED: To provide a method and an apparatus effective to verify whether a platform is included in a data center. SOLUTION: An inclusion verification relates to a server comprising a private key to verify if the server is included in a data-center computer system and at least one token to perform a sealing process of the private key to the server.
