  • Publication number: 20150237562
    Abstract: A receiving device associates a first one-way function value determined by an operation using a one-way function with a first destination. Next, the receiving device determines a second one-way function value by the operation using the one-way function from identification information stored in the receiving device and element information received from a transmitting device. When the second one-way function value is different from the first one-way function value, the receiving device associates the second one-way function value with a second destination, and returns the identification information to the transmitting device.

  • Publication number: 20140295306
    Abstract: In a method for controlling a fuel cell system, a shutoff valve is opened to supply a fuel gas from a storage container to a fuel cell after a fuel cell system shutdown instruction is sent to the fuel cell system so that the fuel cell generates and discharges electricity. The storage container is supplied to the fuel gas supplied from a fuel supply source provided outside the fuel cell system in response to a filling instruction to supply the fuel gas to the storage container. A data signal indicating a state of the storage container is transmitted to the fuel supply source. The shutoff valve is closed and the storage container is supplied to the fuel gas supplied from the fuel supply source if the filling instruction is output while opening the shutoff valve after the fuel cell system shutdown instruction is sent.
