Information-processing system, information-processing apparatus, management apparatus, and processing method

A management apparatus comprising:

• a receiver configured to receive, from a second processor, a request to write a computation circuit to an integrated circuit capable of re-write of circuits, the computation circuit being configured to perform computation according to information transmitted by the second processor;
• and
• a first processor configured to perform control to write the computation circuit and an encryption circuit to the integrated circuit based on first information to be used to write the computation circuit and second information to be used to write the encryption circuit, the encryption circuit being configured to generate encrypted data by encrypting a computation result computed by the computation circuit, by using an encryption key for the computation circuit.

A non-transitory, computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:

• receiving a request to write a computation circuit to an integrated circuit capable of re-write of circuits from another computer, the computation circuit being configured to perform computation according to information transmitted by the another computer;
• and
• performing control to write the computation circuit and an encryption circuit to the integrated circuit based on first information to be used to write the computation circuit and second information to be used to write the encryption circuit, the encryption circuit being configured to generate encrypted data by encrypting a computation result computed by the computation circuit, by using an encryption key for the computation circuit.

A processing method for a computer, comprising causing a processor to:

• receive, from a terminal, a request to write a computation circuit to an integrated circuit capable of re-write of circuits, the integrated circuit being included in an information-processing apparatus;
• and
• perform control to write the computation circuit and an encryption circuit to the integrated circuit based on first information to be used to write the computation circuit and second information to be used to write the encryption circuit.
