Outline of Final Research Achievements

We have realized a combination selection method for cryptographic techniques simply by classifying and modeling typical advanced cryptographic protocols by function and entity and providing a list of combinations that satisfy the requirements using the proposed model. In addition, we conducted a large-scale analysis of Android applications to identify elements to be applied. As a result, we confirmed the existence of official Android APIs and third-party APIs. We improved the analysis method to enable an analysis of these third-party APIs, resulting in a highly accurate and wide-ranging analysis method. The method has been improved to enable an analysis of official Android APIs and third-party APIs. As for cryptographic application support technology, we have successfully implemented support technology for basic cryptographic techniques as an extension to the actual development environment and confirmed and evaluated the practicality of the technology.
