摘要:
An apparatus stores first divided trust information which is one portion resulting from division of trust information generated by a transmission target apparatus that is a transmission target for data, receives a transmission request for the data from the target apparatus and receives second divided trust information which is the other portion resulting from division of the trust information of the target apparatus and verification information generated using information indicating a state of the target apparatus that made the request, recovers the trust information using the first divided trust information stored and the received second divided trust information, verifies trustworthiness of the target apparatus using the recovered trust information and the received verification information, transmits the data indicated by the request to the target apparatus when the verification of trustworthiness is successful.

Provided is information processing apparatus, information processing method and a record medium, which can prevent occurrence of manipulation, in a case of accessing a memory, without consuming the access band of the memory. A main-processing unit, a sub-processing unit and a memory for loading a program are provided and process limit information stored in the memory is stored in storing means. The sub-processing unit judges whether a program to be executed is manipulated or not, and loads a program to be executed in the memory in case that the program is not manipulated. The sub-processing unit refers to the process limit information before execution of a program, and not permits execution of the program of the main-processing unit in case that a process by the main-processing unit for information stored in the memory accords with a process included in the process limit information.

A virtual machine migration method conducted in a virtual machine migration system that includes a virtual machine of a migration source computer and a migrating target computer. The migration source computer conducts processing to send host physical address information of an MMIO region corresponding to a device used by the virtual machine through directed I/O to a migration target computer, and to cause a connection target of the device to be switched to the migration target computer by a switching device that connects the device to the computers. The migration target computer conducts processing to allocate an MMIO region corresponding to the host physical address information sent by the migration source computer, to the device connected to the computers by the switching device.

An I/O device performs data input and data output between the I/O device and first and second computers. An I/O switch relays input and output data between the I/O device and each of the first and second computers. A device emulator emulates the I/O device when a virtual machine running on the first computer and directly accessing the I/O device is migrated from the first computer to the second computer. A connection controller controls switching connection between any one of the first and second computers and any one of the I/O device and the device emulator. The first computer is connected to the I/O device and the second computer is connected to the device emulator until the virtual machine running on the first computer is stopped, and the second computer is connected to the I/O device after the virtual machine running on the first computer is stopped.

An IC chip, a board, information processing equipment, and a storage medium are provided that can prevent, even when information is transferred between a plurality of programs, leaking of the right protection algorithm of information in connection with the transfer. A security board is included an IC chip having a secure module. The secure module receives an encryption key request signal, and generates a communication encryption key every time when the encryption key request signal is received, the communication encryption key being used to encrypt information to be transferred between a plurality of programs. The number of times the communication encryption key is supplied is counted. If the counted number is equal to or less than a predetermined number, the communication encryption key is supplied to outside. If the counted number exceeds the predetermined number, the supply of the generated communication encryption key to outside is stopped.
摘要:
It is an object of the present invention to a method whereby a humoral immune response is induced more efficiently in producing an antibody against an antigen protein by gene immunization. A fusion gene composed of a gene encoding the full-length of a part of the antigen protein or a gene encoding a chaperonin subunit or a chaperonin subunit linkage linked thereto is administered to express the fusion gene in the animal, thereby inducing a humoral immune response to an antigen protein by administering. An example of the chaperonin includes Escherichia coli GroEL. There is also provided with a composition for immunization, a method for producing an antibody, a method for producing a hybridoma, and a method for producing a monoclonal antibody.

In a system for receiving and storing broadcast content data, a reception and storage device receives and stores a portion of broadcast content data in a storage unit, and then generates and stores a first piece of error check data for the data portion. The reception and storage device receives, from a further device, a second piece of error check data for a portion of the broadcast content data corresponding to the data portion stored in the storage unit, compares the first piece of error check data with the second piece of error check data to determine whether the first piece of error check data is valid, receives, if the first piece of error check data is determined to be invalid, the corresponding data portion associated with the second piece of error check data, from another reception and storage device, and corrects the stored data portion in the storage unit based on the received corresponding data portion.
摘要:
In the synchronous motor controlling apparatus and method of the invention, a current is detected and subjected to coordinate transformation onto &ggr;-&dgr; axis assumed for the rotor. A correction term is obtained on the basis of the derived current and an arbitrarily given correction current instruction. A &ggr;-&dgr; axis voltage instruction is computed by adding a value obtained by multiplying the correction term by a proper gain to a voltage equation in a steady state of the synchronous motor. Consequently, a control method of small computational load, which does not require gain adjustment according to the inertia of a motor load, can be attained.

A mobile terminal includes a display device and a processor. The processor acquires first display information about a first virtual machine. The first display information does not prompt a user operation. The processor displays the acquired first display information in a first display area on the display device. The processor acquires second display information about the first virtual machine. The second display information prompts a user operation. The processor displays the acquired second display information in a second display area on the display device. The processor determines, in response to an instruction for changing display, whether mixed display is allowed by referencing status information. The processor acquires, when the mixed display is allowed, third display information about a second virtual machine. The third display information does not prompt a user operation. The processor displays the acquired third display information in a third display area on the display device.
