Abstract: The amphibious unmanned patrol vehicle includes a buoy, a waterproof cable and a submersible amphibious vehicle. An end of the waterproof cable is connected to a first controller of the buoy; and another end thereof is connected to a second controller of the submersible amphibious vehicle. A bottom end of the buoy is connected to a top end of the submersible amphibious vehicle which is configured to realize movement and operation of a whole system. The waterproof cable is configured to connect the submersible amphibious vehicle, and the buoy configured to ensure real-time communication between the submersible amphibious vehicle and an external environment during operation of the submersible amphibious vehicle. A height difference between an upper surface and a lower surface of the automatic reeling and unreeling cable device is equal to a thickness of the waterproof cable. The length of the waterproof cable is adjusted automatically in real time.

Abstract: Embodiments of the present application relate to a method and device for authentication processing. The method includes obtaining an equipment code that uniquely identifies a terminal, generating a dynamic password based at least in part on the equipment code and an output value of a counter, wherein the dynamic password is a basis for authentication of the terminal by a server, and sending the dynamic password to the server, wherein the server authenticates the dynamic password.
