Abstract

It is my honor and privilege to be able to take the first great step in 2019 for Journal of Internet Services and Information Security (JISIS) by publishing the issue 1 of the volume 9. Looking back on 2018, JISIS presented the four issues, which are composed of the sixteen high-qualified papers authored by researchers from ten countries, thereby successfully completing its noble mission. It is natural to thank not only the authors who wrote these valuable articles, but also the editors and reviewers who have devoted themselves to the review process. In 2019, we would like to continue such a success by introducing high-qualified papers, which provide latest and advanced research results in all areas of Internet services and information security. In particular, we will invite outstanding researchers to publish insightful tutorial or survey in their own domain to inspire readers as well as trigger the successive innovations. Additionally, we will invite authors of best papers presented at the sister conferences of JISIS to submit their extended version. Last but not the least, I would like to extend my sincere thanks to the authors of the four papers included in this issue, which opens the volume 9.
