The authors in the article propose two modifications of the method of image encryption based on the use of the ideas underlying the algorithm RSA, in particular the combination of the properties of the RSA algorithm and bitwise additively-difference operations. The advantage of these methods is to maintain resistance to decrypt, which is provided by the RSA algorithm and eliminating the use of visual methods of image processing for decryption. The methods shows best results in the case that makes it easy to highlight contours of images .
