Title:
An information processor and a communication apparatus
Document Type and Number:
Japanese Patent JP6219248
Kind Code:
B2
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.
