PROBLEM TO BE SOLVED: To obtain an excellent remote procedure call method capable of objectively certifying history information related to the execution of a remote procedure. SOLUTION: Since a client repeating part 200 generates a 1st electronic signature corresponding to a request message and transmits the generated signature together with the request message, a server repeating part 300 can check the validity of the request message based on the 1st electronic signature. The server repeating part 300 generates a 2nd electronic signature corresponding to data synthesized from the request message and a response message and transmits the 2nd electronic signature together with the response message, so that the repeating part 200 can check the validity of the response message based on the 2nd signature. The repeating part 200 generates and transmits a 3rd electronic signature corresponding to data synthesized from the request message and the response message, so that the repeating part 300 can check the reception of the response message. |
