1. An information-processing system comprising:

  • a host system with a first processor, an encryption circuit and an integrated circuit capable of reconfiguration of circuits, the first processor being coupled to the integrated circuit;

    a shared memory coupled to the first processor and the integrated circuit;

    a second processor, and a memory coupled to the second processor, the second processor being configured to access the first processor; and

    a computer, separate from the host system, with a third processor configured to manage the first processor, whereinthe first processor is configured to write, to the integrated circuit, a processing circuit, an encryption circuit and identification information for at least an area of the processing circuit,the processing circuit is configured to perform processing, according to information transmitted by the second processor, to provide a service using the identification information,the encryption circuit is configured to generate encrypted data by encrypting a processing result of the processing circuit, by using an encryption key for the processing circuit,the third processor is configured to manage the encryption key in association with the processing circuit and to notify the second processor of the encryption key for the processing circuit, andthe second processor is configured to read out the encrypted data from the memory for storing the encrypted data, and decrypt the read encrypted data by using the encryption key notified from the third processor.
