1. An information-processing system comprising:

  • a first processor, and an integrated circuit capable of re-write of circuits, the first processor being coupled to 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 third processor configured to manage the first processor,wherein the first processor is configured to write, to the integrated circuit, a computation circuit configured to perform computation according to information transmitted by the second processor, and an encryption circuit configured to generate encrypted data by encrypting a computation result computed by the computation circuit, by using an encryption key for the computation circuit,the third processor is configured to manage the encryption key in association with the computation circuit and notify the second processor of the encryption key for the computation 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.
