Research Activities

The emerging information and communication infrastructure such as Internet of Things is expected to generate a new value and bring us a more fruitful society. On the other hand, it brings a new type of security risks that we have never met and solved before. The new risks include the nullification of applications by data forgery and the falsification of critical control information in factories. These risks are not always addressed by conventional technologies and their naïve extensions. We are studying future information systems from theories to implementation technologies for constructing advanced information and communication infrastructures in a safe and secure manner.

Environmentally Conscious Secure Information System(Prof. Homma)

We are studying theories and technologies for developing secure information and communication systems to ensure security and reliability from the level of vast and diverse information sources (i.e., embedded devices such as sensor terminals), not only to ensure the network and software security. We are also studying the security analysis and evaluation technologies for embedded systems that heavily depend on the information and electromagnetic environment where the system is placed. In addition, along with the challenge to the social implementation of the above research results, we are promoting the standardization works through the activities in various standardization committees.

Research topics

  • Hardware algorithms for high-functionality/lightweight cryptography
  • Design and evaluation of embedded system security
  • Electromagnetic information security
  • Environmentally conscious information processing technology
