An Adaptive Energy-efficient SSL/TLS Method for the Internet of Things using MQTT on Wireless Networks

Abstract— Internet of Things (IoT) devices use MQTT, which is a lightweight messaging protocol, with SSL/TLS for security communication. The original SSL/TLS selects a cipher suite that has the highest preference at the negotiation step of a handshake. This selected cipher suite provides a high security level. However, ensuring secure communication can be intensive for IoT devices when providing much higher security than the expected security level. This limitation causes wasting excessive energy use and overhead in the device. In this paper, we propose an adaptive energy-efficient SSL/TLS for IoT devices using MQTT with SSL/TLS. Our proposed method provides suitable security communication that adapts to the environment of the device. The experimental results demonstrate the validity of our proposed method, which leads to an energy savings of 34.72%.

Index Terms— SSL/TLS, Internet of Things, message queuing telemetry transport, security.
