A method for logically binding and verifying devices in an apparatus

The invention claims a logic in the binding verifying and method for device. The method, and a component in device and submodule, is a main module in the device, and sub-module preserves a personalized information respectively, and preserves the submodule personalized information the main module. When the lower antithetical couplet module end of the data; the main module is a submodule transmission and submodule personalized information data information according oneself balanced. The submodule receiving data information, a personalized information of the data information for determining receiving and balanced matched; each, determining a legitimate for running state, otherwise by the illegal for running state. The invention can aiming at the safety technique for and extends from the device is a component layer, a one application prospect.
