Outline of Final Research Achievements

We began with a research topic that focuses on the most motivating application of the proposed scheme. After several trials, it turned out that the requirements of the applications are fairly complex. Therefore, we decided to focus our attention on the methodologies to establish that application, rather than trying to generalize the application. The application was to infer the hostnames of encrypted traffic. To this end, we developed a new scheme called DNG (domain name graph), which captures complex dynamics of DNS name resolutions. Our main research outcomes are as follows: We first published a research paper at IFIP TMA 2015 (acceptance rate = 29.6%). We then published the extended version of the previous paper (we extended the methodology to drastically improve scalability) at Elsevier Computer Communications. We also filed two patents for domestic, and another two patents as PCT. We also presented an invited talk at a domestic conference.
