Q.Encryption methods are typically used for security, and when you think of encryption, people tend to think that any type of information is safe if it is encrypted.
At our lab, were using something called side channel attacks for example, and with this, even if you think your communication signals are generally safe, they arent.
For example, consider the communication route. Communication lines flow along cables. Now, data is generally safe if it flows along a cable, but those lines can be tapped to gain access to that information.
Also, with personal computers, we usually work using a monitor and keyboard,
but radio waves are output by monitors and an antenna can be used to capture those radio waves from a remote location and reproduce the images on the screen.

As a countermeasure to this type of action, were using a variety of hardware tools to completely encrypt signal lines.
Data is encrypted so that its impossible for outsiders to determine where the communication stream ends or to determine if there is any communication or information.


Q.afamily restaurants, cold storage warehouses, schools, and ordinary homes and such so that rather than managing the power grid on a house to house basis, the power is controlled as an entire region in a certain location.
As a result, the overall power grid becomes more efficient and there are no cuts in power during peak demand.

　As for peaks in power demand, when the power demand suddenly increases, the demand can exceed the power generation capacity of solar cells and gas powered AC generators. What were trying to do is build a system that enables efficient consumption of power on a regional basis by controlling the power so that the demand doesnt exceed the power generation capacity and so that the peak can be shifted to a different time.


Q.With networks, we can be connected to all types of things. The study of this connection is basically a pursuit of the relationship between different things.

With that in mind, we have things that we must do as individuals and we are constantly relying on something. That is when we can use networks to link various information and items.
What we want to do next and what type of lifestyle we want in the future are closely connected, and from that perspective, if your dream is to live a certain type of lifestyle and create a certain type of world, then ICT technology can be used to somehow achieve that dream. In fact, thats how weve reached the point that we are at today. I believe that we can achieve these dreams in the future, so my aspiration is to change the world that we live in, and because I have the desire to make changes, I will begin that effort with the use of ICT technology.

If you want to make changes in the world, we want to work with you to make those changes together.
