Authentications for Internet of Things Security: Threats, Challenges and Studies

The Internet of Things (IoT) is attracting attention as the core technology with the development of the wireless network and the universal use of portable terminals. IoT provides high quality service to the user through various technology convergences that are based on smart devices to high performance. However, due to the vulnerabilities connected with complex technologies and problems with implementation methods, there are various security threats. Therefore, to provide the best service, it is necessary to construct a secure environment for security threats in the IoT. It also must be protected and managed the device via authentication or secure policies. In this paper, we describe the security threats, issue and consideration in IoT, and we examine authentication structure, lightweight technology, and key management. We also propose an authentication service scenario based on existing authentication technology and research. Finally, we present the development and research direction of Internet security technology to provide secure service.
