Recently, many laundry home appliances have been released with Internet of Things (IoT) functions, but there are few quality evaluation tests for IoT functions. In particular, since IoT test items are not prepared for laundry home appliances applied with IoT functions, it is difficult to find the cause even if defects occur, and test institutions are limited in selecting test items related to IoT and conducting proper performance tests. In this paper, we design a test item framework that separates IoT test items into commonality and variability to identify product defects and causes for laundry home appliances with IoT features among products in the field of home appliances. Through the proposed research, manufacturers and test institutions can test the proper performance of laundry products with IoT functions, which can improve the completeness of the products and ensure reliability.

Recently, frozen and refrigerated appliances on the market are being released with additional IoT functions, but there are few tests on IoT functions. In particular, the existing test system does not have IoT test items for IoT-based frozen and refrigerated appliances, making it difficult for companies to find the cause even if defects occur, and test institutions are also restricted from selecting IoT-related test items and conducting correct performance tests. In this paper, we design a test item framework that can identify product defects and identify causes in the performance test process of frozen and refrigerated products with IoT functions among products in the home appliance field, and propose test methods and management measures using them. Through the proposed research, manufacturers and testing institutions can test the correct performance of IoT-based frozen and refrigerated products, thereby enhancing the completeness and securing reliability of the products.

In modern times, many IoT products are being used as all things and devices are connected to the Internet and IoT products become easily accessible through the network. For the convenience of users, IoT products can be remotely operated automatically without manual operation. Various research and development are underway to improve the convenience of users by using IoT products. However, since only the convenience of the users is pursued, in terms of security, there is a serious problem that exposes the user's personal information. This paper has proposed a method to apply $moir{\acute{e}}$ technology to IoT products in order to improve the performance of security, and a method to increase the safety of IoT products using user face authentication based on shadow $moir{\acute{e}}$ as a $moir{\acute{e}}$ phenomenon method, and the projection $moir{\acute{e}}$. When comparing the existing IoT products and IoT products applied with $moir{\acute{e}}$ technology, IoT products applied with $moir{\acute{e}}$ technology are safer in terms of security.

Recently, IoT products with various functions are being developed. Through the combination of objects and information technology, convenient services that have not been imagined before are emerging. For a secure IoT environment, product security must be considered. However, the existing IoT products have various problems such as security vulnerability. In order to secure the security of IoT products, technical countermeasures as well as policy responses are needed. However, the legislation related to current IoT products has a limit to guarantee safety in IoT environment. In this paper, we analyze the limitations of the current legal system of IoT, and suggests ways to improve it.

Because security of Internet of Things(IoT) products and others is poor, there are many hacking incidents To prevent security threats, it is important for companies to first make products with high security levels and choose products that are safe for users. In response, the Korea Internet & Security Agency is testing the security of IoT products and linked mobile apps to impose ratings. Security certification service is a service that tests IoT products and linked mobile apps to ensure certain levels of security and issues certificates when they meet the criteria. It can induce autonomous security enhancement of IoT products, contribute to strengthening security capabilities of IoT companies in Korea and vitalizing their overseas advancement, and have the expected effect of resolving public anxiety over IoT products. In this study, the criteria for IoT security certification are presented, but the importance priority is sought to be derived for assessment items that need to be strengthened. This will help to provide guidelines that can contribute to strengthening the security capabilities of domestic Internet companies and boosting their overseas advancement.

As IoT technology develops along with the 4th industrial revolution, gas safety products to which IoT technology is applied are being developed. However, since the gas safety system was not allowed, system improvement and operation reliability test for IoT gas safety products are required. This thesis researches IoT fuse cock and smart multi-function meter among IoT gas safety products, and analyzes the empirical data of IoT fuse cock to secure operational reliability data, thereby becoming a leader in IoT gas safety products. It aims to develop gas barrier technology one step further through various test evaluations and methods in the future.

Today many companies are offering IoT-enabled products and place emphasis on security from the planning stage to protect their products and user information from external threats. The present security levels, however, remain low because the time and resources invested in developing security requirements for each device are far from enough to meet the needs of a wide range of IoT products. Nevertheless, vulnerabilities of IoT devices have been reported continuously, which calls for more detailed security requirements for home IoT devices. In this context, this research identified threats of home IoT systems by using Microsoft Threat Modeling Tool. It then suggested measures to enhance the security of home IoT devices by developing security assessment items through comparative analysis of the identified threats, domestic and global vulnerability assessment standards and related research. It also verified the effectiveness of the developed security requirements by testing them against the existing ones, and the results revealed the security requirements developed in this research proved to be more effective in identifying vulnerabilities.

사물인터넷 (IoT) 기술의 발전으로 최근 많은 가전제품 및 전자 제품들이 IoT 기술과 결합되어 출시되고 있으며, 전원을 연결하는데 사용되는 멀티탭 또한 IoT 기술이 접목된 제품이 나오고 있다. IoT 멀티탭은 전원 on/off 를 원격으로 제어 할 수 있어서 사용자 편의성을 더욱 높여주었다. 그러나, 현재 출시된 IoT 멀티탭 제품들은 각 구별 제어가 불가능하고 대기전력 차단 기능이 미흡하여 절전 기능이 빈약하다. 따라서 본 논문에서는 멀티탭의 각 구를 개별 조작할 수 있고, 대기전력을 측정 및 차단 기능을 제공함으로써 전력 낭비를 줄일 수 있는 IoT 멀티탭을 제안한다.
