“…But these works focus on the gait pattern for key generation between multiple devices of the same user, instead of the devices of different users. The most closely related works are [30,31]. In [30], Bichler et al present a novel approach to establish a secure connection between two devices by shaking them together.…”

“…Instead of distributing or exchanging a key, the devices independently generate a key from the measured acceleration data by appropriate signal processing methods. In [31], Bichler et al further propose an algorithm to independently synchronize the shaken devices so that reliable key generation becomes possible. However, their method requires an additional training phase to extract the detailed profile and pattern of user behaviors on the specified devices, which severely limits its application for different devices and different users.…”

In traditional device-to-device (D2D) communication based on wireless channel, identity authentication and spontaneous secure connections between smart devices are essential requirements. In this paper, we propose an imitation-resistant secure pairing framework including authentication and key generation for smart devices, by shaking these devices together. Based on the data collected by multiple sensors of smart devices, these devices can authenticate each other and generate a unique and consistent symmetric key only when they are shaken together. We have conducted comprehensive experimental study on shaking various devices. Based on this study, we have listed several novel observations and extracted important clues for key generation. We propose a series of innovative technologies to generate highly unique and completely randomized symmetric keys among these devices, and the generation process is robust to noise and protects privacy. Our experimental results show that our system can accurately and efficiently generate keys and authenticate each other.
