Outline of Final Research Achievements

The purpose of this study is to establish a threat analysis method, to construct a computer system to support it, and to prototype a security countermeasure method in order to achieve both safety and security of the highly reliable embedded system. As a system that supports the analysis of security threats, a keyword derived from a list of threats found in the past is compiled into a database, and the keywords can be semi-automatically applied to the design of the system to be analyzed. In order to incorporate countermeasures at the system design stage, existing countermeasure technology including fuzzing testing was included into the database.
