A new method of grid encryption is proposed. The specific definitions of the relevant parameters of the grid density control are given, and these parameters are generally attached to the topological elements in the target B-reps representation. The methods used to deal with the boundary curve discretization, the distribution in the area and the point insertion are described in the process of grid encryption. The examples given are given to illustrate the performance of the proposed grid encryption method.
