Technology trends of access control in IoT and requirements analysis

Since IoT devices can cause problems, such as invasion of privacy and threat to our safety, security in IoT is the most important element. IoT is an environment in which various devices to communicate an environment in which various devices communicate with one another without user intervention or with minimal user intervention. Therefore, authentication and access control technology between IoT devices are important element in the IoT security. In this paper, we describe our survey of access control technique in IoT environment and requirements of it.
