As IT technology develops, IoT technology is being applied in various fields such as home appliances, agriculture, automobiles, and smart homes. In addition, it is developing into an evolved form that intelligently connects people, processes, data, and things. However, with the development of Internet of Things (IoT) technology, although security guidelines, standard technologies, and countermeasures are being presented, the reality is that security incidents against new security threats and vulnerabilities are increasing. The recently developed IoT-based ultra-light devices are limited in the application of high-performance security technology, and vulnerabilities such as unauthorized access, data forgery, personal information exposure and theft, and mis-operation of heterogeneous devices are being announced. In this paper, to prevent unauthorized access, illegal use, and misuse between people and devices or devices, mutual authentication and operation techniques are proposed to strengthen the security of system operation between administrators and users, and the security and integrity of ultra-light IoT devices are proposed. For strengthening, we intend to propose a smart home IoT device operation method using block chain technology by allowing only authenticated users to operate smart home IoT devices with the proposed IC card-based mutual authentication method.
