Abstract： It proposes a secure interaction technology for IoT devices based on palm vibration signals.By analyzing theimpactofdiferences inthebiologicalstructureofusers'palmsonvibrationpropagation，itcolects tapping vibration data and uses time-frequency domain analysis，designs sliding window segmentation signals，constructs deep metric learming models to extract features，andachieve identity authentication.At the same time，using Pulse Width Modulation （PWM） to generate vibration signal encoding control instructions to achieve safe communication.The experiment shows thatthe accuracy of single keystroke authentication is 84.5% ，and continuous keystrokes can improve to 92.4% ，which can effectively defend against side channel attacks and imitation attacks.In terms of communication performance， the system has a maximum transmission rate of 60bit/s ，anaverage bit error rate of 3.29% and an implicit authentication processthat takes lessthan 5O ms，combining securityand real-time performance.
