DAoT: Dynamic and energy-aware authentication for smart home appliances in Internet of Things
Youngpil Kim, Seehwan Yoo, Chuck Yoo · 2015
The Internet of Things (IoT) is beneficial to individuals, business, and society because it creates a wide range of value-added services by interconnecting diverse devices and information objects. However, as IoT devices have resource constraints to employ powerful security mechanisms, they are vulnerable to sophisticated security attacks such as the main-in-the-middle (MITM) attack. Therefore, an intelligent authentication mechanism that considers both resource constraints and security is required. In this paper, we suggest a dynamic and energy-aware authentication scheme for the Internet of Things (DAoT). DAoT uses a feedback control scheme to dynamically select an energy-efficient authentication policy. With DAoT, IoT devices with limited resources can be safely interconnected because DAoT finds and adopts the best cost-effective authentication mechanism.
