RSA ALGORITHM IN FRACTIONAL-RATIONAL N-ARY FORMS WHILE ENCRYPTION-DECRYPTION OF MONOCHROME IMAGES

The basis for image protection is the assumption that the image is a stochastic signal. But the image is a specific signal that possesses, in addition to typical informativeness (informativeness of data), also visual informativeness, which brings new challenges to the issue of protection. Therefore, the urgent task is to implement such application of the RSA algorithm that when encrypting an image: – the cryptographic stability of the RSA algorithm did not deteriorate; – achieves full image noise to prevent the use of visual image processing methods.
