This paper treats one of the activities of a research project about IoT (Internet of Things) security education. In this project, the authors plan to provide SPOC (Small Private Online Course), MOOC (Massive Open Online Course) and education games (serious games) about IoT security. One of the key challenges is the development of educational materials that attract students to IoT security. As a first step, a database will be built that contains the IoT security information for educational materials. So, the authors have already been building a comprehensive database regarding the various kinds of IoT threats based on Linked Data. The other research agenda is to provide e-learning materials themselves using the database that attract students to IoT security. The use of VR (Virtual Reality) and AR (Augmented Reality) technologies enables e-learning materials to attract the students. In this paper, the authors propose e-learning material development framework supporting VA/AR based on Linked Data.
