Abstract

DEM is the key protective resource for data-using departments because of its important military and economic value. This paper gives a specific method for the RSA used in DEM information disguising according to the principle of the RSA algorithm and the characteristics of DEM, and solves the various problems that may occur in the disguising process. Then, this paper analyses the relationship between the elements and impact effect, and makes the security analysis through experiments. This method has a good safety performance, and could provide strong technical support for storage and transmission of DEM data.
