Just Shake Them Together: Imitation-Resistant Secure Pairing of Smart Devices via Shaking
Require: 1) The raw sensor data sequence: . 2) The threshold for accelerometer and gyroscope: and . | Ensure: The start point of the sensor data sequence: . | 1: Initialize a sliding window for each dimension , set the window size to . Initialize the threshold for each dimension according to the sensor type. | 2: for each dimension do | 3: Forward the sliding window along the raw sensor data sequence , calculate the average value inside the window as . | 4: ifthen | 5: Set the start point of the window as . Stop forwarding the window . | 6: Find the first points among the point set for all dimensions. Set the average value of the points as . |
