Abstract
The present invention discloses a method for logically binding and verifying a subassembly in equipments. The method sets the subassembly in the equipment as a sub-module, and setting a main module in the equipment. the sub-module stores individual information of its own and the main module stores the individual information of the sub-module. The main module sends verification information corresponding to the individual information of the sub-module stored in the main module to the sub-module when the sub-module needs to be verified. The sub-module judges whether the received verification information matches the individual information stored by the sub-module itself after receiving the verification information, if they matches, it is determined that the sub-module is in the legal status, otherwise, it indicates that the sub-module is in the illegal status. The burglarproof technique for the equipment in the present invention can be extended from the level of equipment to the subassemblies, and the present invention has broad applications.
