Information processing apparatus and communication device
First Claim
1. An information processing apparatus comprising:
- first circuitry configured to receive a first demand response request from a first communication device; and
second circuitry configured to;
create first request content information representing contents of the first demand response request, from the first demand response request;
send the first request content information to a time-stamping authority, and acquire first time certification information that the time-stamping authority sends in response to this sending, the first time certification information including a time stamp that the time-stamping authority issues for the first demand response request; and
associate the first time certification information with the first demand response request and store the first time certification information in a storage device;
wherein the first circuitry is configured to transmit the received first demand response request and the first time certification information to a second communication device,wherein the second circuitry is configured to, when the first circuitry receives a second demand response request from the first communication device after the first circuitry receives the first demand response request, determine whether the second demand response request is retransmission of the first demand response request; and
wherein the first circuitry is configured to, when the second circuitry determines that the second demand response request is the retransmission of the first demand response request, send the second demand response request and the first time certification information associated with the first demand response request in the storage device, to the second communication device.

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. When it is the retransmission, the second circuitry causes the first circuitry to send the second demand response request and the first time certification information associated with it in the storage device, to a second communication device.

16. An information processing apparatus comprising:
-
first circuitry configured to communicate with a communication device; and second circuitry configured to; when a first demand response request is to be sent from the first circuitry to the communication device, create first request content information representing contents of the first demand response request, from the first demand response request; send the first request content information to a time-stamping authority, and acquire first time certification information that the time-stamping authority sends in response to this sending, the first time certification information including a time stamp that the time-stamping authority issues for the first demand response request; and associate the first time certification information with the first demand response request in a storage device; wherein the first circuitry is configured to transmit the first demand response request and the first time certification information to the communication device, wherein the second circuitry is configured to determine whether a second demand response request to be send to the communication device subsequent to the first demand response request is retransmission of the first demand response request; and wherein when the second circuitry determines that the second demand response request is the retransmission of the first demand response request, the first circuitry is configured to send the second demand response request and the first time certification information associated with the first demand response request in the storage device, to the communication device. - View Dependent Claims (17)
