New Features of Authentication Scheme for the IoT: A Survey

With the development of cloud computing and artificial intelligence, the Internet of Things (IoT) products are gradually entering every corner of our lives and changing the way we live. Yet traditional computer authentication protocol cannot be used directly in the Internet of things devices, because of its limitations (e.g., simple CPU structure, low storage capacity, weak computing power, etc.). Therefore, the authentication protocol for the Internet of Things is an essential ingredient for securing the internet of things. In this paper, we introduce the background of authentication protocol for the Internet of Things, analyze the differences of authentication protocol between computer and Internet of Things, and then illustrates the developing trend of IoT authentication protocol. Based on the thorough survey, we discuss the new features of the authentication protocol for the Internet of Things from three aspects: description, solution. opportunities. At last, we specify some difficulties for the research of authentication protocol in the IoT.
