A multi-host switching docking station and a secure interaction method thereof

Abstract

The application relates to the technical field of docking stations, and discloses a multi-host switching docking station and a safe interaction method thereof.The method comprises the following steps: performing local USB enumeration on a downlink peripheral interface, extracting a device category code, and establishing a device type state table; in response to a switching key triggering event, reading a device category code set from the device type state table, performing safe identification on the device category code set based on a blacklist or a whitelist, and obtaining a device identification result; when the device identification result is safe, outputting a switching control signal to a multiplexer signal switching unit; when the device identification result is risky, activating a multi-modal alarm, entering a secondary confirmation waiting state, and outputting the switching control signal to the multiplexer signal switching unit after detecting a secondary confirmation gesture.The application effectively distinguishes between a user's active forced switching intention and a habitual single-time accidental touch, ensures data safety, and retains the user's final operation autonomy.
