According to an embodiment, a server to which a plurality of power meters each measuring an amount of power consumption of an electric appliance is connected, includes a receiving unit, a first storage unit and a calculating unit. The receiving unit receives a calculation result. The calculation result is calculated based on the amount of power consumption measured by each of the plurality of power meters and each of random numbers generated according to a probability distribution by each of the plurality of power meters. The first storage unit stores therein parameters for generating random numbers. The calculating unit calculates an estimation value of a sum or average of the amounts of power consumption using the calculation results and the parameters. The estimation value is used for determining whether to perform power control.

According to an aspect of the present invention, there is provided a data transmitting apparatus including an authenticator generating unit and a communicating unit. The authenticator generating unit generates a first authenticator by using a first encryption key and generates a second authenticator including a first to an n-th fragment information items by using a second encryption key. The communicating unit transmits a first packet including the first authenticator and the first fragment information item to a destination device and, after the first packet is transmitted, if a response indicating successful authentication is not received from the destination device within a certain period, sequentially transmits an i-th packet (i is an integer being 2 or more and n or less) including the i-th fragment information item to the destination device.
