다양한 IoT 시스템을 위한 안전이 보장된 통신 프레임워크 연구

Abstract

The 4th Industrial Revolution is characterized by super-intelligence and hyper-connectivity. It combines intelligence information technologies (Artificial Intelligence, Internet of Things, Big Data, etc.) with existing industries or new technologies (3D printing, Robotics, biotechnology, etc.) and it is a new concept of industrial paradigm that connects all products to the network and intelligently uses them. IoT (Internet of Things) connects things, such as physical devices, home appliances, items embedded with software, sensors, actuators, etc, to the Internet to collect data from each unit and exchange useful information between them. There exist a variety of application areas for IoT systems including smart home/cities, intelligent transportation systems, industrial control systems, wearables, healthcare, etc. In this these, we focus on M2M-based IoT, industry-based IoT and clustered drones-based IoT systems. In this thesis, we studied security mechanism implementations on M2M-based IoT, industry-based IoT and clustered drones-based IoT systems. First, we proposed network architectures for these three IoT systems. Then, in order to guarantee the stability of the data transmission, the efficient protocols are suggested as well as security mechanisms using Diffie-Hellman key exchange method and Lightweight Encryption Algorithm (LEA) for these systems.
