With the rapid development of IoT(Internet of Things) technology, various convenient services such as smart home and smart city have been realized. However, IoT devices in unmanned environments are exposed to various security threats including eavesdropping and data forgery, information leakage due to unauthorized access. To build a secure IoT environment, it is necessary to use proper cryptographic technologies to IoT devices. But, it is impossible to apply the technologies applied in the existing IT environment, due to the limited resources of the IoT devices. In this paper, we survey the classification of IoT devices according to the performance and analyze the security requirements for IoT devices. Also we survey and analyze the use of cryptographic technologies in the current status of IoT open standard platform such as AllJoyn, oneM2M, IoTivity. Based on the research of cryptographic usage, we examine whether each platform satisfies security requirements. Each IoT open platform provides cryptographic technology for supporting security services such as confidentiality, integrity, authentication an authorization. However, resource constrained IoT devices such as blood pressure monitoring sensors are difficult to apply existing cryptographic techniques. Thus, it is necessary to study cryptographic technologies for power-limited and resource constrained IoT devices in unattended environments.

According to the textbook utilization survey, university students buy 6.4 books and spend 94,000 won per semester. However, nearly half of books are left unused. Therefore many students buy used textbooks instead of buying new books at a fixed price. The existing used textbook trading platforms support basic functions, but don't support textbook recommendation function and reference book recommendation function. In this paper, we developed a used textbook trading platform BookCue that provides textbook recommendation function, reference book recommendation function, and consignment trading function reflecting the regional characteristics. It is expected that will contribute to reduce university students' burden that buying textbook by forming textbooks trading environment and preserve environment. In the near future our platform will need to expand to a platform that deals with a variety of goods, as well as used textbooks in the region.
