| Outline of Final Research Achievements |
As a major research result, we have developed a general formulation of a theoretical model of hardware attacks. We also succeeded in giving necessary and sufficient conditions for secure communication for the problem formulated.
In the formulation, the problem was how to give a measure of safety. In this study, we solved this problem by introducing a practically meaningful scale. In addition, by clarifying the properties of the introduced security measures, we succeeded in deriving the necessary conditions for secure communication. We further obtained a concrete method of code construction keeping secure communication under hardware attacks.
