| Outline of Final Research Achievements |
Previous work on side-channel information, physical information such as power leakage and electromagnetic waves leaked from a cryptographic system, focused on a case study of attacks that analyzed a part of side channel information and acquired a secret key. On the other hand, in this research project, we changed the way of thinking about side-channel information and set up a research framework that effectively utilizes all of the side-channel information. As an application, we proposed and constructed a new cryptosystem such as an authentication system, a ranging device, and an intrusion detection device using side-channel information, and demonstrated the enhancement of security. A series of efforts and understandings on this research topic has contributed to the development of side-channel analysis research.
