  • Information processing apparatus and communication device
    Patent number: 9985754
    Abstract: An information processing apparatus comprises a first circuitry and a second circuitry. The first circuitry first/second demand response requests from first/second communication devices. The second circuitry creates first request content information representing contents of the first demand response request, sends it to a time-stamping authority, and acquires first time certification information containing a time stamp that the time-stamping authority issues for the first demand response request. The second circuitry stores the first time certification information in a storage device to be associates with the first demand response request; and determine, when the second demand response request is received, whether the second demand response request is retransmission of the first demand response request.
