Abstract
Most Internet of Things (IoT) devices have limited computing power and resources. Therefore, lightweight encryption protocols are essential to secure communications between IoT devices. As a promising technique, physical layer key generation has been widely used in IoT applications to secure communication between devices. In this paper, we propose an Efficient and Appropriate Key Generation Scheme (EAKGS) for various IoT scenarios. According to the characteristics of the channel data, we design the pre-judgment stage to classify the values. Considering the key generation requirements and measured values characteristics in different scenarios, we propose efficient key generation schemes for static and dynamic scenarios. Furthermore, we conduct real-world experimental analysis and validation of our scheme. We analyze the feasibility of EAKGS from key generation rate, key error rate and randomness. Our experimental results demonstrate that EAKGS meets the requirements for adaptability and key performance.
