The invention relates to a protector visualization development method based on function components, and belongs to the technical field of development of computer software. The protector visualizationdevelopment method based on the function components comprises the following steps: designing every protection function as an independent function component; determining unique identification codes ofthe function components by sub-module identification codes in the components; and when the function components are reused, verification is implemented by the identification codes of the function components to ensure correctness during reusing and transplanting, the workload of design development is greatly reduced, zero test and zero maintenance of the protection functions are realized, the debugging efficiency is improved, and therefore, the product development period is shortened.
