• Our study focuses on information security technologies for the next-generation ICT society fusing real-world and cyber-space computing. We are now conducting the research and development of ultra-high-speed, ultra-low power LSI computing to perform security functions such as encryption and secure computing, secure implementation technologies to protect systems from various physical attacks (attacks carried out by physical access to the system), and security optimization technologies tailored to the system usage environment and application area.

We can provide collaboration and information exchange services in the fields of information security. In particular, we have experiences of domestic/international collaborative researches on embedded security with some companies, universities, and governmental institutes.

• Our technology provides the necessary method for sending messages even when the physical infrastructure is not available. The technology utilizes common smartphone WiFi functionality to send message in a multi-hop fashion. Thus it is possible to send message to people further away. Our technology has been designed to be based on Delay-Tolerant Networks (DTN), but the technical key idea is the combination of DTN and Mobile Adhoc Network (MANET), which can improve the message delivery in an area with high population density or where mobility are fixed such as evacuation center.

This technology can be used to distribute information during emergency situation such as after disaster. In addition, it is possible to provide additional services such as advertisement within shopping areas, distribution of coupons, exchange of information within small group during public events or uses as transceiver during group hiking. There is also possibility of using this technology to provide communications service in developing nations.

• According to recent studies, each video that is streamed online has its own unique characteristic. The pattern of data that are sent through the network can vary from one encoding method to another and the change from scene to scene, which is a unique characteristic of each video. This research aims to identify video content in the network without looking at the data itself.

This research would be especially useful in preventing illegal distribution of television program such as illegal channel without violating user privacy. Another application would be to prevent confidential online meeting from leaking outside local enterprise network. In addition, it is also possible to investigate the circulation of a video content using method introduced by this work.

• Toward the realization of a ubiquitous and broad-band wireless network, we are actively engaged in the research work on dependable and low power consumption advanced wireless IT. We cover the whole technical fields from the lower to higher layers, i.e., signal processing, RF/Mixed signal device, antenna, MODEM and network technologies.As the studies on signal processing, RF/Mixed signal device and antenna technologies, we are developing RF/Millimeter-wave RF CMOS IC's, antenna integrated 3-dimensional system in package (SiP) transceiver modules, digital/RF mixed signal IC's.
